How can I do that
So far, I've provided 5 different solutions - all with their own advantages and problems - you'll have to test on your own data and hardware to ensure that it's working for you!
I did the following (all the relevant code is available on the fiddle here):
CREATE TABLE t (x TEXT);
and populated it with some text similar to yours, but shorter to making testing easier:
INSERT INTO t VALUES
($SOMETAG$with t(x) as (values( XMLPARSE(DOCUMENT ('<root><NotificationServiceDetails NotificationNo="0" AlarmCode="mail" AlarmStartTime="10:00:00" AlarmTime="0" Id ="2" ><NotificationServiceDetail Id="2"><Title><![CDATA[aaaaaaaaaaaaa]]></Title><ContentJson><![CDATA[
<html lang="en">
<head>
<meta charset="utf-8"/>
more stuff
more stuff
</table>
</body>
</html>
]]></ContentJson></NotificationServiceDetail></NotificationServiceDetails></root>'))))
select
unnest((xpath('//NotificationServiceDetails/NotificationServiceDetail/#Id',t.x)))::text::integer as Id,
unnest((xpath('//NotificationServiceDetails/NotificationServiceDetail/Title/text()',t.x))):: text::character varying as Title,
unnest(xpath('//NotificationServiceDetails/NotificationServiceDetail/ContentJson/text()',t.x))::xml as ContentJson,
t.x
from t;$SOMETAG$);
I picked up the $SOMETAG$...$SOMETAG$ technique here - very helpful for insterting characters like single quote (') and backslash (\).
There is a "one-pass" solution possible - it justs takes time patience to work it out. Oh, and BTW, there were slight errors in my orininal solution - since corrected.
Part 1:
First I remove all characters up to but not including <html lang="en"> as follows:
SELECT SUBSTRING(x, STRPOS (x,'<html lang="en"'));
SUBSTRING and STRPOS were taken from this snippet.
Part 2:
Then, I reverse that string using the REVERSE() function
Part 3:
Finally, I use the SUBSTRING/STRPOS "trick" to chop of the other end of the string to the point of <ydob>
Part 4 is the pièce de résistance
I reREVERSE() the string to bring it back to its original state - minus the undesirable bits to give the required result.
1st Solution (pretty horrible):
SELECT REVERSE(SUBSTR( REVERSE(SUBSTR(x, strpos(x, '<html lang="en">'))), strpos( REVERSE(SUBSTR(x, strpos(x, '<html lang="en">'))), '>lmth/<'))) FROM t;
It looks a bit better (or is more legible at lease):
SELECT
REVERSE(
SUBSTR(
REVERSE(
SUBSTR(x, strpos(x, '<html lang="en">'))),
strpos(
REVERSE(
SUBSTR(x, strpos(x, '<html lang="en">'))), '>lmth/<'))) FROM t;
Instead of these horrible constructions, I used CTE's (Common Table Expressions - AKA the WITH CLAUSE to do this as follows:
Code spends most of its life in maintenance, so easier to read code is easier to repair.
WITH cte1 AS
(
SELECT REVERSE(SUBSTR(x, strpos(x, '<html lang="en">'))) AS s1 FROM t
), cte2 AS
(
SELECT REVERSE(SUBSTR(s1, strpos(s1, 'ydob'))) AS s2 FROM cte1
)
SELECT * from cte2;
Result:
reverse
<html lang="en">
<head>
<meta charset="utf-8"/>
more stuff
more stuff
</table>
</body>
</html>
The answer is the same for all of them!
2nd Solution (a bit more elegant - fiddle available here):
SELECT SPLIT_PART(x, '</html>', 1) from t;
Result:
split_part
with t(x) as (values( XMLPARSE(DOCUMENT ('<root><NotificationServiceDetails NotificationNo="0" AlarmCode="mail" AlarmStartTime="10:00:00" AlarmTime="0" Id ="2" ><NotificationServiceDetail Id="2"><Title><![CDATA[aaaaaaaaaaaaa]]></Title><ContentJson><![CDATA[
<html lang="en">
<head>
<meta charset="utf-8"/>
more stuff
more stuff
</table>
</body>
<<=== Note there are 7 spaces here
So, SPLIT_PART() cuts the string up to, but not including the delimiter - </html> in this case. So, using this as follows:
So, we combine two SPLIT_PARTs in a CTE as follows:
WITH cte AS
(
SELECT LENGTH(split_part(x, '', 1)) AS beg,
LENGTH(split_part(x, '', 1)) AS fin
FROM t
)
Result:
substring
<html lang="en">
<head>
<meta charset="utf-8"/>
more stuff
more stuff
</table>
</body>
</html>
-- I cannot understand why I have to add 8 characters to the 408 of the length?
--
-- 7 (the length of </html>) I could possibly get, but why 8?
Which is the desired result.
3nd Solution (also reasonably elegant - fiddle available here):
I didn't go through all of the steps this time - I combined them all in one query. The interested reader is invited to go through it line by line.
SELECT
strpos(x, '<html lang="en">'),
strpos(x, '</html>'),
strpos(x, '</html>') - strpos(x, '<html lang="en">'),
substring(x FROM strpos(x, '<html lang="en">')
for ((strpos(x, '</html>') + 8) - strpos(x, '<html lang="en">')) )
FROM t;
--
-- Again, I'm puzzled by the necessity to use 8 characters.
--
--
Result:
strpos strpos ?column? substring
265 409 144 <html lang="en">
<head>
<meta charset="utf-8"/>
more stuff
more stuff
</table>
</body>
</html>
Et voilà - the desired result!
4th Solution (a bit convoluted, but may be instructive - fiddle available here):
1st Step:
I split the lines into records in a table as follows:
SELECT
x.idx,
LENGTH(x.string),
x.string
FROM t,
REGEXP_SPLIT_TO_TABLE(t.x, '\n') WITH ORDINALITY AS x(string, idx);
2nd step:
I pull out the records I want which correspond to the desired result as follows:
WITH cte1 AS
(
SELECT
x.idx,
LENGTH(x.string) AS ls,
x.string
FROM t,
REGEXP_SPLIT_TO_TABLE(t.x, '\n') WITH ORDINALITY AS x(string, idx)
), cte2 AS
(
SELECT idx, ls, string
FROM cte1
WHERE string ~ '<html lang="en">' OR string ~ '</html>'
ORDER BY idx
)
SELECT idx, ls, string
FROM cte1
WHERE idx BETWEEN
(SELECT MIN(idx) FROM cte2) AND (SELECT MAX(idx) FROM cte2);
Result:
idx ls string
2 22 <html lang="en">
3 12 <head>
4 33 <meta charset="utf-8"/>
5 20 more stuff
6 20 more stuff
7 16 </table>
8 13 </body>
9 14 </html>
As you can see, the string field contains the data we want!
Solution 5 - using a relatively simple regular expression - fiddle here
1st pass:
We check the output of the very handy PG_TYPEOF() function, which from the docco here does:
pg_typeof returns the OID of the data type of the value that is passed
to it. This can be helpful for troubleshooting or dynamically
constructing SQL queries. The function is declared as returning
regtype, which is an OID alias type (see Section 8.18); this means
that it is the same as an OID for comparison purposes but displays as
a type name.
So, our first query is:
SELECT
REGEXP_MATCH(x, '^.*(<head>.*</html>).*'),
PG_TYPEOF(REGEXP_MATCH(x, '^.*(<head>.*</html>).*'))
FROM t;
Result:
regexp_match pg_typeof
{"<head>
<meta charset=\"utf-8\"/>
more stuff
more stuff
</table>
</body>
</html>"} text[]
So, we have our data, but it's surrounded by braces (curly brackets) - but we know from our PG_TYPEOF() function is a text array, so we know that it's the first (only) element of that array, so therefore we can use the array element notation as follows:
SELECT
(REGEXP_MATCHES(x, '^.*(<head>.*</html>).*'))[1] -- <<-- Note [1]
FROM t;
Result:
regexp_matches
<head>
<meta charset="utf-8"/>
more stuff
more stuff
</table>
</body>
</html>
Same as the others!
Which is the same as for the others!
Crude performance analysis
After 5 runs, the order of merit appears to be the following (a fiddle of the tests run may be found here. Times will vary according to other uses to which the server may be being put, but as I said, I found them to be fairly consistent in terms of time and always in the same order on the 5 runs that I examined.
In descending order of run time:
1st) Method 3: STRPOS() Time ~ 0.045ms: - let that be a base of 1 times fastest execution
2nd) Method 1 SUBSTRING() & REVERSE() 0.079ms: x times 1.75
3rd) Method 2: SPLIT_PART() x times 2.25
4th) Method 4: REGEXP_SPLIT_TO_TABLE() WITH CTE x times 13.2
5th Method 5: REGEXP_MATCH() x times 49.4
So, we can see that the most expensive algorithm is ~ 50 times more expensive than the most efficient one. The usual caveats about benchmarking with only one record and on an unknown system apply - although the results where fairly consistent over at least 5 runs. Always benchmark on your own system with your own data!
I need to match the color of each line in a chart to the color given by the object providing the data. The meter.color variable holds the color I need to use.
<StackLayout class="container" orientation="vertical">
<Label class="title" [text]="widget.settings.title" horizontalAlignment="center"></Label>
<RadCartesianChart class="chart" tkExampleTitle tkToggleNavButton>
<ng-container *ngFor="let meter of readings$ | async">
<ng-container [ngSwitch]="meter.type">
<LineSeries tkCartesianSeries seriesName="Line" *ngSwitchCase="'line'" [legendTitle]="meter.name + ' - ' + meter.unit"
[items]="meter.data" stackMode="Stack" categoryProperty="timestamp" valueProperty="value">
<Palette tkCartesianPalette seriesName="Line">
<PaletteEntry tkCartesianPaletteEntry [strokeColor]="meter.color"></PaletteEntry>
</Palette>
</LineSeries>
<SplineSeries tkCartesianSeries seriesName="Spline" *ngSwitchCase="'spline'" [legendTitle]="meter.name"
[items]="meter.data" stackMode="Stack" categoryProperty="timestamp" valueProperty="value">
<Palette tkCartesianPalette seriesName="Spline">
<PaletteEntry tkCartesianPaletteEntry [strokeColor]="meter.color"></PaletteEntry>
</Palette>
</SplineSeries>
</ng-container>
<RadLegendView tkCartesianLegend position="Top" title="Series" enableSelection="true"></RadLegendView>
<RadCartesianChartGrid tkCartesianGrid horizontalLinesVisible="true" verticalStrokeColor="#804d0026"></RadCartesianChartGrid>
<LinearAxis tkCartesianVerticalAxis horizontalLocation="Left" android:labelFormat="%.0f"></LinearAxis>
<DateTimeContinuousAxis tkCartesianHorizontalAxis dateFormat="hh:mm" [minimum]="backwardHour" [maximum]="forwardHour"
majorStep="Hour" labelFitMode="Rotate"></DateTimeContinuousAxis>
</ng-container>
</RadCartesianChart>
</StackLayout>
At the moment the line gets one color and the spline get another. But if i have more than two lines or splines all lines get the same color and all splines also get the same color. It seems that the last line added sets the color of both lines, the same goes for the spline.
I found a solution to my problem, i added property binding to seriesName on both the LineSeries and to the PaletteEntry witch matches each line dynamically to a ID.
Changes in my code:
<LineSeries tkCartesianSeries [seriesName]="meter.id" *ngSwitchCase="'line'" [legendTitle]="meter.name + ' - ' + register.unit" [items]="register.data" stackMode="Stack" categoryProperty="timestamp" valueProperty="value">
<Palette tkCartesianPalette [seriesName]="meter.id">
<PaletteEntry tkCartesianPaletteEntry [strokeColor]="meter.color"></PaletteEntry>
</Palette>
</LineSeries>
For Ex. I have an arraylike this cids:Array=[{Id:1},{Id:2},{Id:3},{Id:4},{Id:5},{Id:6},{Id:7}---------etc..]
I want output as :
1 2 3 4
5 6 7 8
9
Using *ngFor in angular 4
One way is to convert your arrray[] in array[][4]. And then you will be able to use an imbricated ngFor (ngFor in another ngFor)
Pseudo code :
ngFor* {
ngFor* {
print value;
insert a space;
}
Insert a return line;
}
<span *ngFor="let cid of cids">
{{cid.Id}}
<br *ngIf="(cid.Id)%4==0" />
</span>
I have a grid in which I want to set the width for auxheader in .zul but it's not working. I am using zk framework.
<grid id="chartGrid" model="#bind(vm.chartGridModel)" mold="paging"
style="overflow:auto" width="100%" >
<auxhead hflex="2" >
<auxheader hflex="2" align="center" width="200px" label="Date" rowspan="3"/>
</auxhead>
<auxhead hflex="1" children="#bind(vm.legendsFB)" visible="#bind(vm.vFb)" >
<auxheader align="center" width="200px" colspan="1"></auxheader>
<template name="children">
<auxheader align="center" label="#bind(each)" colspan="#bind(
vm.viewType eq '0' ? 3 :2)" hflex="2"/>
</template>
</auxhead>
<columns visible="false"><!-- make it invisible -->
<column width="200px"/><!-- specify width here -->
<column width="150px"/>
<column width="50px"/>
<column width="50px"/>
</columns>
<template name="model">
<row>
<cell align="center" ><label value="#load(each.report_date)"></label>
</cell>
<cell align="center"><label value="#load(each.total_action)"></label>
</cell>
<cell align="center"><label value="#load(each.from_user_male)"></label>
</cell>
<cell align="center"><label value="#load(each.from_user_female)"></label>
</cell>
</row>
</template>
</grid>
You set width and colspan.
colspan="x" means you will take the witdh of x columns of your template.
Now you can remove the colspan and it should work, but remember when you set width in px,
Be sure that the total px are the same as the px of all your rows.
You can also do width = "20%", this would mean that you take 20% of your total size of px of the columns.
Its easier to calculate to 100% then your total px.
Greetz chill.
Cant get the CUR status working. the menue always have the classes marked with 0 instead of those marked with 2. what i am doing wrong? My typoscript code:
10.marks {
MENU_OBEN = HMENU
MENU_OBEN {
special = directory
special.value = 10
1 = TMENU
1 {
wrap = <ul>|</ul>
noBlur = 1
NO = 1
NO {
allWrap = <li class="first0"> | </li> |*| <li class="normal0"> | </li> |*| <li class="last0"> | </li>
stdWrap.wrap = <strong> | </strong> |*| | |*| <b> | </b>
}
CUR = 1
CUR {
allWrap = <li class="first2"> | </li> |*| <li class="normal2"> | </li> |*| <li class="last2"> | </li>
stdWrap.wrap = <strong> | </strong> |*| | |*| <b> | </b>
}
}
}
Don't see anything obvious, but have you tried removing the NO = 1 line? IIRC the normal ("NO") state doesn't need to be explicitly set, as long as you set some properties for it... maybe by setting it explicitly you're overriding the state?
In my general ts template I have no NO=1. Instead I copy the NO status into CUR. I really dont know why, but it works for me this way.
e.g.
NO.wrapItemAndSub = <li> | </li>
NO.stdWrap.htmlSpecialChars = 1
CUR < .NO
CUR = 1
CUR.ATagParams = class="cur"
ACT < .NO
ACT = 1
ACT.ATagParams = class="act"
Keep in mind that for page shortcuts this cannot work, since if you klick on a shortcut you never are on the page which is supposed to become active/current.
Just change the page property to standard page and set "Display Content of Page" in "Apperance" Tab.
