Subject: [xsl] Converting an element tree to a string representation From: Nicholas Piper <nick-xsllist@xxxxxxxxxxxxxxx> Date: Wed, 3 Sep 2003 16:22:39 +0100 |
I've had a good look at http://www.dpawson.co.uk/xsl/index.html, and google. Google is hard, because I can't think of good keywords; I may have missed something in the list archive for that reason too. I'm trying to write a series of XSLT files to transform an XHTML+MathML document into new documents that can be shown on 'big browsers', PDA browsers, WML phones, etc. I'm planning to manage the MathML thin browsers by converting a block like this: <math xmlns="http://www.w3.org/1998/Math/MathML"> <mi>S</mi> </math> in my source document, to this in my output document: <img src="http://i.haus/i/el/mathml_to_png.py?math=%3Cmath++++ xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F1998%2FMath%2FM athML%22%3E%3Cmi%3ES%3C%2Fmi%3E%3C%2Fmath%3E"> (obviously without the line breaks). Then my python script converts that XML fragment into a PNG, or WBMP, etc. I've got the server-side part sorted, but am having very great difficulty trying to convince my xslt engine (xmlspy, xsltproc) to output what I'd like. My current attempt looks like: <xsl:template match="math:math"> <img> <xsl:attribute name="src"> http://i.haus/cgi-bin/mathmltopng?m=<xsl:value-of select="."/> </xsl:attribute> </img> </xsl:template> But of course this doesn't work, I just get [...] src="http://i.haus/cgi-bin/mathmltopng?m=Cost=_n=1_(-1)nn" [...] as it concatenates together the text nodes, rather than reproducing the node as a string. Is what I want to do possible? Should I pre or post-process the file with a parser of my own, instead of trying to do this with an XSLT engine? That doesn't seem quite as nice.
