Hi All,

I could not find a dedicated libxml2/libxlst group so I thought I
would see if anyone here could help.

I have a system which captures the stdout from various sources and
writes it into a generic xml file. This file then needs to be
transformed to get the correct html format for rendering in a
webserver.

I am using the following code to perform the translation:

styledoc = libxml2.parseFile('stdout.xsl')
style = libxslt.parseStylesheetDoc(styledoc)

doc = libxml2.parseFile('stdout.xml')
result = style.applyStylesheet(doc, None)

style.saveResultToFilename('stdout.html'), result, 0)

style.freeStylesheet()
doc.freeDoc()
result.freeDoc()

Given the following stdout.xml sample:

<report>
<stdout>some app spew...</stdout>
<stdout>laa laaa laa...</stdout>
<stdout>something interesting &lt;badthinghappening&gt;</stdout>
</report>

It seems that the resultant 'stdout.html' file shows the final stdout
message translated too:

<stdout>something interesting <badthinghappening></stdout>

which of course results in a badly formed file with a missing tag :(

How do I get libxml2/libxlst to not touch the '&lt;' and '&gt;'

Cheers
-Shaun

My mistake! *doh*

I had an 'disable-output-escape="YES"' when it should have been "NO".

Eeeeven though you figured out your problem: have you checked out lxml?
Its extremely capable and ISTM much easier to use then whatever direct
wrapper you seem to be using.

Check out: http://codespeak.net/lxml/xpathxslt.html#xslt
