在SOAP消息中使用XSLT替换命名空间uri

我有一条输入soap消息，试图用不同的字符串替换命名空间uri的一部分。我可以用不同的URI替换整个URI，但不能修改现有的URI。我需要查找“OLDSTRING”并替换为“NEWSTRING”。字符串VARIABLESTRING在每个输入xml中都不同，因此我应该保持输出xml中的原样

输入XML:

睾丸

输出XML:

睾丸

我已经尝试了以下XSL，并且能够更改名称空间URI，但是我只想将“OLDSTRING”替换为“NEWSTRING”，并保持其余字符串不变

XSLT:

这是否符合您的要求

<?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="{replace(namespace-uri(), 'OLDSTRING', 'NEWSTRING')}" >
            <xsl:apply-templates select="@*|*|text()" />
        </xsl:element>
    </xsl:template>

</xsl:stylesheet>

这种处理在XSLT 2.0中很容易，但在XSLT 1.0中相当棘手：

No，XPath 1.0/XSLT 1.0中没有

replace（）

函数。在发布代码之前测试代码是个好主意。
