I have an XSLT template that transforms this:
<WGS__LAT>N20340000</WGS__LAT>
to this:
<latitude>
<deg>20</deg>
<min>34</min>
<sec>00</sec>
<hSec>00</hSec>
<northSouth>North</northSouth>
</latitude>
I wrote an XSpec scenario to test the XSLT template:
<x:scenario label="location/latitude: Check that the XSLT assigns latitude the split-up value of WGS__LAT">
<x:context>
<WGS__LAT>N20340000</WGS__LAT>
</x:context>
<x:expect label="Expect: deg=20, min=34, sec=00, hSec=00, northSouth=North">
<latitude>
<deg>20</deg>
<min>34</min>
<sec>00</sec>
<hSec>00</hSec>
<northSouth>North</northSouth>
</latitude>
</x:expect>
</x:scenario>
I am certain that my XSLT template works correctly, so why does the XSpec tool report FAILED? I thought it might have something to do with whitespace in <x:expect> so I removed all whitespace:
<x:expect label="Expect: deg=20, min=34, sec=00, hSec=00, northSouth=North">
<latitude><deg>20</deg><min>34</min><sec>00</sec><hSec>00</hSec><northSouth>North</northSouth></latitude>
</x:expect>
Unfortunately, I still get FAILED. What am I doing wrong?
Without having the full report, and especially what you actually get, it's difficult to answer. But :
in that case, a going starting point is to wrap your context in another tag, and to set in the xspec which part of the result should match. Something like :
<x:context>
<foo>
<WGS__LAT>N20340000</WGS__LAT>
</foo>
</x:context>
<x:expect label="..." test="/foo/*" as="element(latitude)">
<latitude>
<deg>20</deg>
<min>34</min>
<sec>00</sec>
<hSec>00</hSec>
<northSouth>North</northSouth>
</latitude>
</x:expect>
You may have a look at wiki for more precise use of expectations.
Then, actual result and expected result are compared with fn:deep-equals(...) method. And so, there is no output processing on result or on expect. Il you use an #href on x:context or on x:expect, then there is a space-normalization, but I'm not perfectly sure of that.
You may have a look at this issue on indentation problems ; it's a quite long and still open thread.

I am trying to get specific data from an XML file, namely X, Y coordinates that are appear, to my beginners eyes, attributes of an element called "Point" in my file. I cannot get to that data with anything other than a sledgehammer approach and would gratefully accept some help.
I have used the following successfully:
for Shooter in root.iter('Shooter'):
print(Shooter.attrib)
But if I try the same with "Point" (or "Points") there is no output. I cannot even see "Point" when I use the following:
for child in root:
print(child.tag, child.attrib)
So: the sledgehammer
print([elem.attrib for elem in root.iter()])
Which gives me the attributes for every element. This file is a single collection of data and could contain hundreds of data points and so I would rather try to be a little more subtle and home in on exactly what I need.
My XML file

UPDATE: Thanks for the answers so far. I tried the solution posted and ended up with 7000 lines of which wasn't quite what I was after. I should have explained in more detail. I also tried (as suggested)
def find_rec(node, element, result):
for item in node.findall(element):
result.append(item)
find_rec(item, element, result)
return result
print(find_rec(ET.parse(filepath_1), 'Shooter', [])) #Returns <Element 'Shooter' at 0x125b0f958>
print(find_rec(ET.parse(filepath_1), 'Point', [])) #Returns None
I admit I have never worked with XML files before, and I am new to Python (but enjoying it). I wanted to get the solution myself but I have spent days getting nowhere.
I perhaps should have just asked from the beginning how to extract the XY data for each ShotNbr (in this file there is just one) but I didn't want code written for me.
I've managed to get the XY from this file but my code will never work if there is more than one shot, or if I want to specifically look at, say, shot number 20.
How can I find shot number 2 (ShotNbr="2") and extract only its XY data points?
Assuming that you are using:
xml.etree.ElementTree,
You are only looking at the direct children of root.
You need to recurse into the tree to access elements lower in the hierarchical tree.
This seems to be the same problem as ElementTree - findall to recursively select all child elements
which has an excellent answer that I am not going to plagiarize.
Just apply it.
Alternatively,
import xml.etree.ElementTree as ET
root = ET.parse("file.xml")
print root.findall('.//Point')
Should work.
See: https://docs.python.org/2/library/xml.etree.elementtree.html#supported-xpath-syntax
Programming Gatling performance test I need to check, if the HTML returned from server contains a predefined string. It it does, break the test with an error.
I did not find out how to do it. It must be something like this:
val scn = scenario("CheckAccess")
.exec(http("request_0")
.get("/")
.headers(headers_0)
.check(css("h1").contains("Access denied")).breakOnFailure()
)
I called the wished features "contains" and "breakOnFailure". Does Gatling something similar?
Better solutions:
with one single CSS selector:
.check(css("h1:contains('Access denied')").notExists)
with substring:
.check(substring("Access denied").notExists)
Note: if what you're looking for only occurs at one place in your response payload, substring is sure more efficient, as it doesn't have to parse it into a DOM.
Here ist the solution
.check(css("h1").transform((s: String) => s.indexOf("Access denied"))
.greaterThan(-1)).exitHereIfFailed
You can write it very simple like:
.check(css("h1", "Access denied").notExists)
If you are not sure about H1 you can use:
.check(substring("Access denied").notExists)
IMO server should respond with proper status, thus:
.check(status.not(403))
Enjoy and see http://gatling.io/docs/2.1.7/http/http_check.html for details
EDIT:
My usage of CSS selector is wrong see Stephane Landelle solution with CSS.
I'm using substring way most of the time :)
I writing editor with netbeans7 and ANTLR4
I have line in my.g4 file
Label : {(getCharPositionInLine()==0)}? ID;
That works well for static files, but while editing getCharPositionInLine() returns 0 often in other places.
How get a real position in lexer?
updated
I created example with this problem
https://github.com/daimor/SimpleANTLR
Your error is likely in the way you are constructing your lexer and/or input stream (i.e. code that you have not shown here). The predicate you describe above will work as expected for an ANTLR 4 lexer.
Also, if getCharPositionInLine()==0, then exactly one of the following conditions is also true:
_input.index()==0
_input.LA(-1)=='\n'
I have the following Problem, given this XML Datastructure:
<level1>
<level2ElementTypeA></level2ElementTypeA>
<level2ElementTypeB>
<level3ElementTypeA>String1Ineed<level3ElementTypeB>
</level2ElementTypeB>
...
<level2ElementTypeC>
<level3ElementTypeB attribute1>
<level4ElementTypeA>String2Ineed<level4ElementTypeA>
<level3ElementTypeB>
<level2ElementTypeC>
...
<level2ElementTypeD></level2ElementTypeD>
</level1>
<level1>...</level1>
I need to create an Entity which contain: String1Ineed and String2Ineed.
So every time I came across a level3ElementTypeB with a certain value in attribute1, I have my String2Ineed. The ugly part is how to obtain String1Ineed, which is located in the first element of type level2ElementTypeB above the current level2ElementTypeC.
My 'imperative' solution looks like that that I always keep an variable with the last value of String1Ineed and if I hit criteria for String2Ineed, I simply use that. If we look at this from a plain collection processing point of view. How would you model the backtracking logic between String1Ineed and String2Ineed? Using the State Monad?
Isn't this what XPATH is for? You can find String2Ineed and then change the axis to search back for String1Ineed.
I have some XML which looks like this:
<?xml version='1.0'?>
<methodResponse>
<params>
<param>
<value><array><data>
<value><array><data>
<value><dateTime.iso8601>20100508T14:49:56</dateTime.iso8601></value>
<value><string></string></value>
<value><string>comment</string></value>
<value><string></string></value>
<value><string>Milestone milestone1 deleted</string></value>
<value><int>1</int></value>
</data></array></value>
</data></array></value>
</param>
</params>
</methodRepsonse>
NSXMLParser seems to not be giving any data back for the blank values resulting in an array with 4 items in it instead of 6.
Is there anything I can do to NSXMLParser to make it return an empty string for the blank values so that I can maintain the order of the data when it is returned?
So after whipping up a quick sample with a delegate that just prints out what's happening during parsing I don't see anything at all wrong with what's being parsed.
I suspect however that you're relying on an incorrect expectation that between calls to didStartElement... and didEndElement... you should get a foundCharacters... call with an empty string? My question is based on the way you phrased the title of your question because there's no such thing as a "blank value." Either there is a value, or there isn't.
Imagine instead your XML contained <string/> instead of the exactly equivalent <string></string>. You still get start/end notifications.
You should be creating your NSMutableString (presumably the type that you're using for your <string> elements) in didStartElement... when <string> is found, appending to that string IF foundCharacters... is called (it can get called more than once with the value in chunks), and tossing it into your array when it's done on didEndElement....
If you really want to be more robust, you'll also be wanting detect an error condition if you find the start of a new element before your string ends, assuming that it is in fact an error for you.
Not quite sure I understand your problem here. NSXMLParser would at least report the beginning and end of the elements. Would that not be enough the get them in the right order?
