Re: [xsl] XSLT processor and substring-after

[JBryant@xxxxxxxxx]

Sorry, but I've not used Perl's XML/XSL facilities. Perhaps one of the 
list's other members has, though.

Re: [xsl] XSLT processor and substring-after






Hi Jay,

Thank you very much! I think the path is correct, but my processor does 
not 
support XPath well. I'm usingXML::XSLT with a depedency on XML::Parser not 

on XPath. Do you know Perl XSLT module supporting XPath 1.0 or higher? I 
know Saxon but I prefer CGI script.

The full source data:

<?xml version="1.0" encoding="ISO-8859-1" ?>
     <wfs:FeatureCollection xmlns:wfs="http://www.opengis.net/wfs"; 
xmlns:gml="http://www.opengis.net/gml";>
        <gml:boundedBy>
           <gml:Box srsName="epsg:4326">
              <gml:coordinates>-89,43 -95,43</gml:coordinates>
           </gml:Box>
       </gml:boundedBy>
</wfs:FeatureCollection>

My XSL is:

<?xml version='1.0' ?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
xmlns:wfs="http://www.opengis.net/wfs"; 
xmlns:gml="http://www.opengis.net/gml"; 
xmlns:b="http://www.opengis.net/examples"; 
xmlns="http://www.fgdc.gov/fgdc/gc"; xmlns:saxon="http://icl.com/saxon";>
<xsl:output method="xml" standalone="yes" omit-xml-declaration="no" 
encoding="ISO-8859-1"/>

<xsl:template match="/">
<Points>
   <gml:boundedBy>
     <gml:Envelope>
        <xsl:variable name="coords1" 
select="wfs:FeatureCollection/gml:boundedBy/gml:Box/gml:coordinates"/>
            <gml:lowerCorner>
                 <xsl:value-of select="substring-before($coords1,' ')"/>
            </gml:lowerCorner>
            <gml:upperCorner>
                 <xsl:value-of select="substring-after($coords1,' ')"/>
            </gml:upperCorner>
      </gml:Envelope>
    </gml:boundedBy>
</Points>
</xsl:template>
</xsl:stylesheet>

Thanks again.

N Zhou
