I have an XML document that contains XPATH references like the

<ROOT>
<DATAID>1</DATAID>
<DATAS>
<DATA>
<ID>1</ID>
<TYPE>Type1</TYPE>
</DATA>
<DATA>
<ID>2</ID>
<TYPE>Type2</TYPE>
</DATA>
</DATAS>
<DATA reference="/ROOT/DATAS/DATA[1]/ID" />
</ROOT>
In my XSLT, I need to be able to acquire the /ROOT/DATA/@reference
string and then using some type of evaluation extension, I need to be
able to obtain the value pointed to by the XPATH of this attribute.
Therefore, the select result would yield '1'.
I've read I could use XALAN-J or EXSLT; however I am unclear how to:
1. Install these extensions in my web application
2. Reference them for use in my XSLT.
Can someone give me a quick and dirty step-by-step of how to do this?
Saxon is an XSLT 2.0 processor implemented in Java so you can use that
instead of Xalan-J.
In its commercial versions (or in the 9.1 release) it has an extension
function
http://www.saxonica.com/documentation/extensions/functions/evaluate-node.xml
you can use e.g.
<xsl:template match="/ROOT/DATA">
<xsl:variable name="ref" select="saxon:evaluate-node(@reference)"
xmlns:saxon="http://saxon.sf.net/"/>
</xsl:template>
