Xml 使用XSLT生成特定元素的XPath

我需要帮助创建一个XSL，该XSL将从XML为其生成XPATH

输入到XSL的XML如下所示。Element标记将包含必须获取Xpath的元素的名称。SampleXML将包含必须从中获取XPath的XML：

<XMLInput>
<Element>FirstName</Element>
<SampleXML>
    <Member>
        <MemberInfo>
            <FirstName>John</FirstName>
            <MiddleName>M</MiddleName>
            <LastName>Doe</LastName>
        </MemberInfo>
        <MemberAddress>
            <State>NY</State>
            <Country>USA</Country>
        </MemberAddress>
    </Member>
</SampleXML>

这里有一种方式可以让你看到它：

XSLT1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="utf-8"/>

<xsl:template match="/XMLInput">
    <xsl:for-each select="//*[name()=current()/Element]">
        <!-- generate a path up to - but not including - ancestor SampleXML -->
        <xsl:for-each select="ancestor-or-self::*[not(descendant-or-self::SampleXML)]">
            <xsl:text>/</xsl:text>
            <xsl:value-of select="name()"/>
        </xsl:for-each>  
    </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

您可能需要添加一个分隔符，以防有多个同名元素

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="utf-8"/>

<xsl:template match="/XMLInput">
    <xsl:for-each select="//*[name()=current()/Element]">
        <!-- generate a path up to - but not including - ancestor SampleXML -->
        <xsl:for-each select="ancestor-or-self::*[not(descendant-or-self::SampleXML)]">
            <xsl:text>/</xsl:text>
            <xsl:value-of select="name()"/>
        </xsl:for-each>  
    </xsl:for-each>
</xsl:template>

</xsl:stylesheet>
