Этот тип обработки прост в XSLT 2.0, но довольно сложен в XSLT 1.0 :
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ext="http://exslt.org/common" exclude-result-prefixes="ext">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:param name="pTarget" select="'OLDSTRING'"/>
<xsl:param name="pRepl" select="'NEWSTRING'"/>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match=
"*[starts-with(namespace-uri(), 'urn:schemas')
or
namespace::*[starts-with(., 'urn:schemas')]
]">
<xsl:variable name="vNS" select="namespace-uri()"/>
<xsl:variable name="vNewNS">
<xsl:choose>
<xsl:when test="not(contains($vNS, $pTarget))">
<xsl:value-of select="$vNS"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="substring-before($vNS, $pTarget)"/>
<xsl:value-of select="$pRepl"/>
<xsl:value-of select="substring-after($vNS, $pTarget)"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:element name="{name()}" namespace="{$vNewNS}">
<xsl:copy-of select=
"namespace::*
[not(. = $vNS
or
starts-with(., 'urn:schemas')
and
contains(., $pTarget)
)
]"/>
<xsl:for-each select=
"namespace::*
[starts-with(., 'urn:schemas')
and
contains(., $pTarget)
]">
<xsl:variable name="vNewNSUri" select=
"concat(substring-before(., $pTarget),
$pRepl,
substring-after(., $pTarget)
)
"/>
<xsl:variable name="vPrefix" select="name()"/>
<xsl:variable name="vPref">
<xsl:if test="$vPrefix">
<xsl:value-of select="concat($vPrefix, ':')"/>
</xsl:if>
</xsl:variable>
<xsl:variable name="vrtfDoc">
<xsl:element name="{$vPref}dummy"
namespace="{$vNewNSUri}"/>
</xsl:variable>
<xsl:copy-of select=
"ext:node-set($vrtfDoc)/*/namespace::*[. = $vNewNSUri]"/>
</xsl:for-each>
<xsl:apply-templates select="node()|@*"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
когда это преобразование применяется к предоставленному документу XML :
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:urn="urn:schemas-OLDSTRING-com:VARIABLESTRING">
<soapenv:Header/>
<soapenv:Body>
<requestMessage xmlns="urn:schemas-OLDSTRING-com:VARIABLESTRING">
<merchantID>TESTID</merchantID>
</requestMessage>
</soapenv:Body>
</soapenv:Envelope>
желаемый, правильный результат получается :
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:urn="urn:schemas-NEWSTRING-com:VARIABLESTRING">
<soapenv:Header />
<soapenv:Body>
<requestMessage xmlns="urn:schemas-NEWSTRING-com:VARIABLESTRING">
<merchantID>TESTID</merchantID>
</requestMessage>
</soapenv:Body>
</soapenv:Envelope>
