Attribute issue in X-Path expression - xslt

Question

Below is my input XML
<ServiceIncident xmlns="http://b2b.ibm.com/schema/IS_B2B_CDM/R2_2">
<ServiceProvider>
<Person Role="AffectedUser">
<ContactID>ITELLA_BRIDGE_USER</ContactID>
<FullName>Chad Whaley</FullName>
</Person>
</ServiceProvider>
In the output in Person Role i need to get Role in place of AffectedUser in the above code Role is an attribute for person.Below is my XSLT
xmlns:r2="http://b2b.ibm.com/schema/IS_B2B_CDM/R2_2">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="r2:Person#Role">
<xsl:copy>Owner</xsl:copy>
</xsl:template>
</xsl:stylesheet>

Answer 1

Your input is not valid XML. Hopefully you have valid XML. I'm assuming this:
<ServiceIncident xmlns="http://b2b.ibm.com/schema/IS_B2B_CDM/R2_2">
<ServiceProvider>
<Person Role="AffectedUser">
<ContactID>ITELLA_BRIDGE_USER</ContactID>
<FullName>Chad Whaley</FullName>
</Person>
</ServiceProvider>
</ServiceIncident>
Your XSLT is also not XSLT, the beginning is missing. I'm assuming that it starts with <xsl:stylesheet somewhere.
Under all the assumtions, the XSLT transformer gives me quite a clear error message:
'r2:Person#Role' is an invalid XPath expression.
This can be fixed to r2:Person/#Role.
Next, <xsl:copy> does not work for you. Maybe you want
<xsl:attribute name="Role">Owner</xsl:attribute>
So finally we have
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xml:space="default" exclude-result-prefixes="" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:r2="http://b2b.ibm.com/schema/IS_B2B_CDM/R2_2">
<xsl:output method="xml" indent="yes" />
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*" />
</xsl:copy>
</xsl:template>
<xsl:template match="r2:Person/#Role">
<xsl:attribute name="Role">Owner</xsl:attribute>
</xsl:template>
</xsl:stylesheet>
