输出如下

如何检索语句的所有XPath，NameLookups？

以下是产生预期输出的XSLT 2.0样式表。您可以在线试用here。

<强>样式表

模板不包含NameTextItems的ID，因为您只在问题文本中提及它们，但它们不会出现在预期的输出中。

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
    <xsl:output method="text" encoding="UTF-8" />

    <xsl:template match="/">
        <xsl:text>Product ID: </xsl:text>
        <xsl:value-of select="//Code[@Scheme = 'GTIN']"/>
        <xsl:text>&#x0a;</xsl:text>
        <xsl:apply-templates/>
    </xsl:template>

    <xsl:template match="Statements | Statement | Name | NameLookups">
        <xsl:value-of select="local-name()"/>
        <xsl:text> ID: </xsl:text>
        <xsl:value-of select="@Id"/>
        <xsl:text>&#x0a;</xsl:text>
        <xsl:apply-templates/>
    </xsl:template>

    <xsl:template match="text()"/>

</xsl:transform>

<强>输出
