在 SOAP 消息中使用 XSLT 替换命名空间 uri [英] replace namespace uri using XSLT in SOAP message
问题描述
我有一个输入soap消息,试图用不同的字符串替换部分命名空间uri.我可以用不同的 URI 替换整个 URI,但不能修改现有的 URI.我需要寻找OLDSTRING"并替换为NEWSTRING".字符串 VARIABLESTRING 在每个输入 xml 中都不同,所以我应该在输出 xml 中保持原样
i have an input soap message, trying to replace part of namespace uri with a different string. I am able to replace entire URI with a different URI, but not able to modify the existing URI. I need to look for 'OLDSTRING' and replace with 'NEWSTRING'. The string VARIABLESTRING varies in in every input xml, so I should keep as it is in the output xml
输入 XML:
Input 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>
输出 XML:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:schemas-NEWSTRING-com:transaction-data-1.69">
<soapenv:Header/>
<soapenv:Body>
<requestMessage xmlns="urn:schemas-NEWSTRING-com:VARIABLESTRING">
<merchantID>TESTID</merchantID>
</requestMessage>
</soapenv:Body>
</soapenv:Envelope>
我已经尝试了以下 XSL,并且能够更改命名空间 URI,但我只想将 'OLDSTRING' 替换为 'NEWSTRING' 并保持剩余字符串不变.
I have tried the following XSL, and able to change the namespace URI, but i want to replace only 'OLDSTRING' with 'NEWSTRING' and keep remaining string as it is.
XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="@*|*|text()" />
</xsl:copy>
</xsl:template>
<xsl:template match="//*[namespace-uri()='urn:schemas-OLDSTRING-com:VARIABLESTRING']">
<xsl:element name="{local-name()}" namespace="urn:schemas-NEWSTRING-com:VARIABLESTRING" >
<xsl:apply-templates select="@*|*|text()" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
推荐答案
这种处理在 XSLT 2.0 中很容易,但在 XSLT 1.0 中很棘手:
<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>
当此转换应用于提供的 XML 文档时:
<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>
产生想要的、正确的结果:
<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>
