[lxml-dev] Problem with lxml library running on Windows

[Roberto Carrasco]

Hi:

We have an issue with libxml library running on Windows.
We are trying to read an xml document from a string over and over but the
program crashes in the while loop. We suspect the problem is that we cannot
run the function etree.parse too much times when we are reading a xml
document from a string. The code crashes when the program read a xml
document repeatedly.
The issue is on Windows becuase on an Linux environment there is no problem
excecuting it.

We are trying to execute the piece of code shown below in this environment:

   - Windows XP Service Pack 2
   - Python 2.5
   - lxml 1.3.4 and 2.0 alpha 3

The question is: what we are doing wrong? or is this a problem with the
library running on Windows?

# -*- coding: UTF-8 -*-
from lxml import etree
from StringIO import StringIO

if __name__ == "__main__":

    document="""    <doc type="Ficha Visado" id="2">
        <attribute name="Rut Afiliado" type="string">1-3</attribute>
        <attribute name="Fecha Escaneo" type="date">2006-03-13

        <attribute name="Suc Promotor" type="string">SANTIAGO</attribute>

            <link href="1-0.img" rel="media"/>
            <link href="1-1.img" rel="media"/>
        </doc>
    </doc>"""

    j=0
    while 1:
        print j
        j+=1

        #tree = etree.parse(StringIO(docRauco0))
        tree = etree.fromstring(document)
        images_url = tree.xpath('//link[@rel="media"][@href]')
        image_url_name=images_url[0].attrib['href']
