Question

I have a input and desired output xml file , but not able to write generic xsl transformer for that. Can anybody here help me out ? address/billing may have more elements at runtime, which should be directly copied to main person block.

<searchPersonResponse>
 <persons>
  <person>
   <name>name2</name>
   <address>
   <billing>
     <city>xx</city>
     <state>yyyy</state>
     <zip>zzzzz</zip>
   </billing>
   </address>
  </person>
  <person>
    <name>name1</name>
    <address>
      <billing>
       <city>xx</city>
       <state>yyyy</state>
       <zip>zzzzz</zip>
      </billing>
    </address>
   </person>
  </persons>
 </searchPersonResponse>

desired output xml

<searchPersonResponse>
 <persons>
  <person>
     <name>name2</name>
     <city>xx</city>
     <state>yyyy</state>
     <zip>zzzzz</zip>
  </person>
  <person>
       <name>name1</name>
       <city>xx</city>
       <state>yyyy</state>
       <zip>zzzzz</zip>
   </person>
  </persons>
 </searchPersonResponse>

Answer 1

EDITED: OP is only looking to “unwrap” address and billing elements when address is present with a billing child. XSLT now does that. Also, OP mentions needs a XSLT 1.0 solution; no XSLT 2.0 features were being used, so I simply changed the version to “1.0”.

This XSLT:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">
    <xsl:template match="@*|node()">
        <xsl:copy>
                <xsl:apply-templates/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="address[child::billing]|billing[parent::address]">
        <xsl:apply-templates/>
    </xsl:template>
</xsl:stylesheet>

When applied to this XML:

<searchPersonResponse>
    <persons>
        <person>
            <name>name2</name>
            <address>
                <billing>
                <city>xx</city>
                <state>yyyy</state>
                <zip>zzzzz</zip>
                </billing>
            </address>
        </person>
        <person>
            <name>name1</name>
            <address>
                <billing>
                <city>xx</city>
                <state>yyyy</state>
                <zip>zzzzz</zip>
                </billing>
            </address>
        </person>
    </persons>
</searchPersonResponse>

Produces the desired result:

<searchPersonResponse>
    <persons>
        <person>
            <name>name2</name>
            <city>xx</city>
            <state>yyyy</state>
            <zip>zzzzz</zip>
        </person>
        <person>
            <name>name1</name>
            <city>xx</city>
            <state>yyyy</state>
            <zip>zzzzz</zip>
        </person>
    </persons>
</searchPersonResponse>

The identity template will copy all nodes and attributes. The address and billing matching template (which matches either element) will copy their children but not themselves.
