I have simple HTML file with usernames and links to their sub-pages:
someUserName#domain.com
someUserName
I use
xpath('.//a/text()').extract_first()
to extract user name in plain text.
I have a problem when user specifies username in form of email (see first example) - empty object in returned in such case.
Edit: I have just noticed html has changed recently and I haven't rechecked:
<td><span class="__cf_email__" data-cfemail="3f4d565c544c5e514bwer4rwre58525e5653115c5052">[email protected]</span></td>
I'll extract from #href.
I have used the following code:-
import scrapy
inputString = '''<xmlData>
someUserName#domain.com
someUserName
</xmlData>'''
print scrapy.selector.Selector(text=inputString).xpath('.//a/text()').extract_first()
Output:-
someUserName#domain.com
Can you paste full python code? Because, xpath code seems working fine as:-
scrapy.selector.Selector(text=inputString).xpath('.//a/text()').extract_first()
Getting the text node children of an element (using text()) is generally discouraged, for exactly the reasons demonstrated here. With <a>content</a> you will get "content", with <a><span>content</span><a> you will get nothing, with <a>h<sub>2</sub>o</a> you will get two text nodes, "h" and "o".
Use string() to get the string value instead. The string value contains the concatenated content of all the descendant text nodes at any depth. ("content", "content", and "h2o" in these three examples).
Only reservation is that I don't know the Scrapy API so I don't know how it handles XPath expressions that return strings rather than nodes.

I have been trying to rewrite some logic to use IText7 that I had previously working with ITextSharp (5.x) but ran into a roadblock. GetTranslatedFieldName no longer existed so I did a quick search and found it in SignatureUtilities but the result doesn't match the actual field name. I assumed that maybe I was misusing it so I dug around a bit more and found FindFieldName on the AcroForm but it returns the same incorrect field name.
Is this a bug or am I still misusing these methods? Is there a native way to Retrieve the full field name from a partial name in IText7?
For reference this is what my full field name looks like
someFormX[0].Page1[0].FieldX[0]
And this is what the field name being returned by GetTranslatedFieldName and FindFieldName looks like
someFormX[0].FieldX[0]
I'm calling a REST API with a SharePoint Designer workflow on SharePoint online. I'm setting the column name with a variable, and when i put the variable into my URL to call it it says "Column [name] does not exist".
Annoying part is when I call just /items? I can see the column in the result, but if I try select it or filter by it I get 'does not exist'. I have alot of these columns similarly named, and I get the error for all of them.
I am using the internal name, I have tried adding "OData_" to the front. I've tried typing the url manually in the browser and entering values (incase the variable was causing issues) but I get the same error, column does not exist. but i can see it them I call all items. :(
so I have quite a few columns with naming convention "[Q#] Score [#]" eg "Q4 Score 2". The internal name that's clearly appearing in the full items results is "Q4_x0020_Score_x0020_2".
This works:
https://MYSITE.sharepoint.com/sites/portal/intranet/CorpServices/QSR/_api/web/lists/GetbyTitle('Audit')/Items?
and I get big full normal REST results that includes the line:
0
However if I try:
https://MYSITE.sharepoint.com/sites/portal/intranet/CorpServices/QSR/_api/web/lists/GetbyTitle('Audit')/Items?$Select=Q4_x0020_Score_x0020_2
Then I get:
-2146232832, Microsoft.SharePoint.SPExceptionColumn 'Q4_x0020_Score_x0020_2' does not exist. It may have been deleted by another user.
I expect to be able to select that column (and the dozens like it) but none work. I've searched all similar problems on the forum and they've usually got a spelling mistake or forgot the ODATA_ but i cant seem to get the problem. Please help.
It seemed to be working intermittently.... So it was in fact just a naming error...... Half of the columns were [Q#]_x0020_Score_x0020_[#] and half were [Q#]_x0020_score_x0020_[#]. The word "Score" was capitalized on some and not others. I Didn't realize the HTTP Calls were case sensitive. Now I have added a bunch of if statements to handle the different variations haha. Thanks for reading.
Judging by the naming convention you are on an older version of SharePoint. The x0020 is the value for a space. Ideally when you first create the column you would name it without the spacing. For example UserInformation. Then come in and edit the name after the fact and call it User Information. If you click on the title name and look at the URL, you will see what the actual name of the column is at the end of the URL. It is case sensitive because you can have a column named score and Score which is ultimately why it wasn't working.
Must load all fields like this
var lists = context.Web.Lists;
context.Load(lists);
context.ExecuteQuery();
CamlQuery query = new CamlQuery();
query.ViewXml = #"";
var list = lists.GetById("file.guid");
var listitems = list.GetItems(query);
context.Load(listitems);
context.ExecuteQuery();
var creationInformation = new ListItemCreationInformation();
var newItem=list.AddItem(creationInformation);
var fields = list.Fields;
context.Load(fields);
context.ExecuteQuery();
I am trying to send a search input to a REST service. In some cases the form input is a long string of numbers (example: 1234567890000000000123456789). I am getting 500 error, and it looks like something is trying the convert the string to a number. The data type for the source database is a string.
Is there something that can be done in building the query string that will force the input to be interpreted as a string?
The service is an implementation of ArcGIS server.
More information on this issue per request.
To test, I have been using a client form provided with the service installation (see illustration below).
I have attempted to add single and double quotes, plus wildcard characters in the form entry. The form submission does not error, but no results are found. If I shorten the number("1234"), or add some alpha numeric characters ("1234A"), the form submission does not error.
The problem surfaced after a recent upgrade to 10.1. I have looked for information that would tie this to a known problem, but not found anything yet.
In terms of forcing the input to be interpreted as a string, you enclose the input in single quotes (e.g., '1234567890000000000123456789'). Though if you are querying a field of type string then you need to enclose all search strings in single quotes, and in that case none of your queries should be working. So it's a little hard to tell from the information you've provided what exactly you are doing and what might be going wrong. Can you provide more detail and/or code? Are you formatting a where clause that you are using in a Query object via one of Esri's client side API's (such as the JavaScript API)? In that case, for fields of data type string you definitely need to enclose the search text in single quotes. For example if the field you are querying were called 'FIELD', this is how you'd format the where clause:
FIELD = '1234'
or
FIELD Like '1234%'
for a wildcard search. If you are trying to enter query criteria directly into the Query form of a published ArcGIS Server service/layer, then there too you need to enclose the search in single quotes, as in the above examples.
According to an Esri help technician, this is known bug.
While testing code in the google chrome developer console, i get
[]
and sometimes i get "".
The later shows up,when i think there not such strings available with the current selector combinations.But i still couldn't figure out the meaning of the former [] square brakets.
Please help.
With the information that you've given, all we can do is make assumptions. However, when you're logging things to the console, [] is an empty array, whereas "" is an empty string.
[] are returned whenever you jquery returns empty object. i.e. you selector expression cant locate what you are trying to search.
whereas "" is just simple string
i looked into your given site..
when i tried :
$('.four columns alpha') i get object[] (which means there jquery is returning empty object)
but when you write correct expression like :
$('.four.columns') you will get array of Div's which can be used like object.
Hope i'm able to make you understand. if any doubts do write.
And $('.four columns alpha') this is not the right way to select div's with more than one css class right way is to do something like below:
$('.four.columns.alpha')
I have the following code:
$("#auto").autocomplete({
source: "js/search.php",
minLength: "3" });
This code is assign to an input text box where i type a name and after 3 letters it should return the ones that have similar letters. For my case it is returning all values, even those not related to the 3 letters already typed. My question is:
How to send my search.php file the value inside the input so it should know what to search for. For the moment it searches for everything. I checked the value that was going to php and it was empty. Since the query to mysql uses LIKE '%VARIABLE%' and the variable is empty it searches for '%%' which is all cases.
How can i send the correct informacion from JS to PHP with the simplest form.
Here is the explanation :
