in reply to Storing Substitution Output String

Perhaps it's because now that I have a hammer, everything looks like a nail, but that sounds like an ideal use for XSLT. I've had a great deal of luck using XML::LibXML and XML::LibXSLT in conjunction to do things very like what you're describing.

Your script would be something along the lines of:

#!/usr/bin/perl -wT use strict; use XML::LibXSLT; use XML::LibXML; my $page2 = "<root> <title>First title</title> <othertag>Other stuff</othertag> <title>Second title</title> <othertag>More other stuff</othertag> </root>"; my $parser = XML::LibXML->new(); my $xslt = XML::LibXSLT->new(); # assumes you've got the XML doc as a string in $page2 my $source = $parser->parse_string($page2); # assumes your XSL file is convert.xsl my $style_doc = $parser->parse_file('convert.xsl'); my $stylesheet = $xslt->parse_stylesheet($style_doc); my $results = $stylesheet->transform($source); print $stylesheet->output_string($results);

* Code above adapted from the XML::LibXSLT docs

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" versi +on="1.0"> <xsl:template match="/"> <root> <xsl:apply-templates select="//root/title"/> </root> </xsl:template> <xsl:template match="title"> <li> <xsl:text>A</xsl:text> <xsl:value-of select="."/> <xsl:text>C</xsl:text> </li> </xsl:template> </xsl:stylesheet>

The above script and XSL file together yield the following output:

<?xml version="1.0"?> <root><li>AFirst titleC</li><li>ASecond titleC</li></root>

This may well be too heavy handed if your project is relatively small, but if there are more chunks you are trying to capture in similar ways, you might consider such an approach.

    Thanks to everyone suggesting xslt--you've guessed part of what's happening here, but I'm trying to go at it slightly differently. You might like one of my sites... Daily Rotation
