xslt - merge multiple XML files using STAX parser

Question

I have multiple XML files.all nodes are similar. Please provide an example how to merge XML files using STAX Parser and apply a stylesheet on it.

Answer 1

If you want to apply XSLT to several XML documents then (with pure XSLT, I don't know about Stax) you can simply use the document function (XSLT 1.0 and 2.0) or the collection function (with XSLT 2.0) e.g.

<xsl:template match="/">
  <root>
    <xsl:apply-templates select="document('file1.xml')/* | document('file2.xml')/* | document('file3.xml')/*"/>
  </root>
</xsl:template>

then add templates matching the element names in the documents you want process.
