Question

Giving this kind of XML file :

<data> 
    <row val="3"/> 
    <row val="7"/> 
    <row val="2"/> 
    <row val="4"/> 
    <row val="3"/> 
</data>

I need to retrieve the string ‘3;7;2;4;3’ using XPath 1.0 so that I can create dynamic links for the Google Chart service in my XForms application.

How can I do that ? Is it possible ?

Answer 1

XPath 2.0 solution:

string-join(/data/row/@val,';')

XSLT 1.0 solution:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="text"/>
    <xsl:template match="row">
        <xsl:value-of select="concat(substring(';',1,position()-1),@val)"/>
    </xsl:template>
</xsl:stylesheet>

EDIT: Short XSLT 1.0 solution.
