<?xml version="1.0"?>
<staff>
<user>
<id>A</id>
<rank>User</rank>
</user>
<user>
<id>B</id>
<rank>User</rank>

</staff>
<?xml version="1.0"?>
<staff>
<user>
<id>A</id>
<rank>User</rank>
</user>
<user>
<id>B</id>
<rank>User</rank>
</user>
<user>
<id>C</id>
<rank>Administrator</rank>
</user>
</staff>

I have to promote to "Administrator" a random user using XPath.
How can I do it?

Re: [PHP] How to change a value with XPath

Here is a stylesheet which will do what you want

XML, XSLT and XPATH Syntax (Toggle Plain Text)
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
 
   <!-- pass in as -param uid "'value'"  -->
   <xsl:param name="uid"/>
 
   <xsl:output method="xml" indent="yes"/>
 
   <xsl:template match="/">
      <xsl:element name="staff">
      <xsl:apply-templates select="//user"/>
      </xsl:element>
   </xsl:template>
 
   <!-- output nodes that match -->
   <xsl:template match="user">
      <xsl:if test="id=$uid">
          <xsl:element name="user">
              <xsl:element name="id"><xsl:value-of select="$uid"/></xsl:element>
              <xsl:element name="rank">Administrator</xsl:element>
          </xsl:element>
      </xsl:if>
      <xsl:if test="id!=$uid">
          <xsl:copy-of select="."/>
      </xsl:if>
   </xsl:template>
 
</xsl:stylesheet>
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

   <!-- pass in as -param uid "'value'"  -->
   <xsl:param name="uid"/>

   <xsl:output method="xml" indent="yes"/>

   <xsl:template match="/">
      <xsl:element name="staff">
      <xsl:apply-templates select="//user"/>
      </xsl:element>
   </xsl:template>

   <!-- output nodes that match -->
   <xsl:template match="user">
      <xsl:if test="id=$uid">
          <xsl:element name="user">
              <xsl:element name="id"><xsl:value-of select="$uid"/></xsl:element>
              <xsl:element name="rank">Administrator</xsl:element>
          </xsl:element>
