Hello guys,

I have following XML:

<example>
    <someNode>
            <value>asas</value>
            <name>asas</name>
            <space>12</space>
    </someNode>
    <interestingNode>
            <con>someString</con>
            <follow>
                    <node1>1</node1>
                    <node2>2</node2>
                    <node3>3</node3>
                    <node4>4</node4>
            </follow>
            <space>5</space>
    </interestingNode>
</example>


Now i want to transform it to:

<example>
    <someNode>
            <value>asas</value>
            <name>asas</name>
            <space>12</space>
    </someNode>
    <interestingNode>
            <con>someString</con>
            <follow>
                    <return>0</return>
            </follow>
            <space>5</space>
    </interestingNode>

    <node1 space="5">1</node1>
    <node2 space="5">2</node2>
    <node3 space="5">3</node3>
    <node4 space="5">4</node4>
</example>


The changes are:
- when interestingNode is found, we check the con value
- if con value conforms someString, then we make transformation of this part 
by:
    - evrything in follow node is moved outside interestingNode
    - follow node gets one child return
    - all nodes moved outside get an attribute space with value
specified in original node


<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:template match="example">
  <xsl:apply-templates/>
</xsl:template>

<xsl:template match="interestingNode[con='someString']">
  <interestingNode>
    <xsl:copy-of select="con" />
    <follow>
      <return>0</return>
    </follow>
    <xsl:copy-of select="space" />
  </interestingNode>
  <xsl:variable name="space" select="space" />
  <xsl:for-each select="follow/*">
    <xsl:copy>
      <xsl:attribute name="space" select="$space" />
      <xsl:copy-of select="node()" />
    </xsl:copy>
  </xsl:for-each>
</xsl:template>

<xsl:template match="*">
  <xsl:copy-of select="." />
</xsl:template>

</xsl:stylesheet>

This template matches the interestingNode, then generates two blocks of
output - first the slightly altered interestingNode, then the list of
<node> tags.

Hope that helps,

        Ronan
