Extracting portion of xml

[elmpp]

Hey,

I'm working with an xml feed which contains portions of rss, latex and mathML. I'm trying to create a gif image using the mathML portions, by passing to a binary using system() (php). Problem is, i see no way of extracting the xml using xslt and preserving the tags, ie doing a <xsl:value-of select="blah"> results in the text nodes of the children returned. Thought there must be a way of selecting a nodeset and then calling a function to kind of serialize it back into xml as text.

Probably more of a xsl problem, but any help would be great. Don't wanna be parsing the document myself to be honest

Hello,

If you want the element blah with all the child elements and their tags you should use <xsl:copy-of select="blah"/> instead of <xsl:value-of select="blah"/> in the XSLT stylesheet. I think you can write a stylesheet which only extracts the MathML part, apply it by calling an XSLT processor from PHP or other language and convert the result of the transformation which is a MathML document to an image.

Thanks so much - was actually resorting to passing the element id to a php function inside xslt and recursively parsing the xml for the portion i wanted. Had a nice little ini_set for execution time set to 900 seconds. I expect this may drop now...

Thanks again.
