Question

Here is my XML :

<root>
<parameters>
<parameter>
    <key>sEmail</key>
    <value>[e-mail]</value>
    <type>string</type>
    <length>255</length>
</parameter>
<parameter>
    <key>sFirstName</key>
    <value>Bill</value>
    <type>string</type>
    <length>40</length>
</parameter>
</parameters>
<root>

I want to retrieve the value of the key sEmail and add it as an attribute to the root element using XML to XML xslt.

Here is the result expected :

<root email="[e-mail]">
<parameters>
    <parameter>
        <key>sEmail</key>
        <value>[e-mail]</value>
        <type>string</type>
        <length>255</length>
    </parameter>
    <parameter>
        <key>sFirstName</key>
        <value>Bill</value>
        <type>string</type>
        <length>40</length>
    </parameter>
</parameters>
<root>

Something similar to this link but with value of element instead of attributes.

Can someone help me ? Thanks

You can test if a subelement’s value is ‘sEmail’:

<xsl:stylesheet version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="parameters">
    <parameters>
      <xsl:attribute name="email">
        <xsl:value-of select="parameter[key='sEmail']/value"/>
      </xsl:attribute>
      <xsl:copy-of select="*"/>
    </parameters>
  </xsl:template>

  <xsl:template match="node() | @*">
    <xsl:copy>
      <xsl:apply-templates select="node() | @*"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>
