Counting Elements in an xml file

[Ouray Viney]

Hi All:

I am looking at writing a python script that will let me parse a
TestSuite xml file that contains n number of TestCases.

My goal is to be able to count the <TestCaseelemen ts base on a key
value pair in the xml node.

Example

<Testcase execute="true" name="foobar">

I would like to be able to count the number of TestCases that contain
the "execute=tr ue" but not the ones that contain "execute=false" .

I have review the python docs and various python ebooks.

Does anyone have any experience with this sort of thing? If so, could
you suggest a good library and possibly some samples?

Thanks

Isn't the SAX part of this howto

http://pyxml.sourceforge.net/topics/howto/xml-howto.html

enough for you to create your parser?

import xml.etree.Eleme ntTree as ET

tree = ET.parse("filen ame.xml")

count = 0

for elem in tree.findall(".//Testcase"):
if elem.get("execu te") == "true":
count += 1

print "found", count, "test cases"

# tweak as necessary

With XPath-capable libraries, it should be enough to execute an XPath
query on the document. For example:

import libxml2dom
d = libxml2dom.pars e(filename)
number_of_cases = d.xpath("count(//Testcase[@execute='true'])")

This applies the XPath count function to all Testcase elements in the
document having an execute attribute with a value of 'true', thus
returning the number of matching elements.

Hi All:

Thank you very much for all your valuable input. All the examples
provided are exactly what I need to get started.

Enjoy the long weekend (for those in North America).

Cheers

You might try the `count` function in the module here:

http://gflanagan.net/python/projects/python-rattlebag/elementfilter.html

The pseudo xpath would be something like:

/Testcase[@execute=="true "]
