如何使用XSLT找到具有某些属性值的所有嵌套XML节点

Question

我的多级深XML（长期为示例非常抱歉），在各个级别上包含错误消息的节点。这些节点都具有@ID的属性，以" _ERROR_MESSAGE"结尾。我正在尝试使用XSLT SELECT将所有这些错误收获到一个平面列表中，但是由于某种原因，Select只能找到两个这样的节点，而根本无法获取其文本。我在做什么错？

结果：

<root>
   <myErrorTest/>
   <myErrorTest/>    
</root>

xslt

<xsl:template match="global-instance">
    <xsl:for-each select="@* | node()[contains('_error_message',@id)]">
         <xsl:element name="myErrorTest"><xsl:value-of select="text()"/></xsl:element>
    </xsl:for-each>
</xsl:template>
<xsl:template match="@* | node()">
    <xsl:copy>
        <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
</xsl:template>

xml

    <entity id='form'>
        <outcome id="form_error_message">xxx</outcome>
        <outcome id="payment-due"/>

您有contains的论点错误的方式，而您的select仅在查看global-instance的直接子女，而不是更深入的后代。

<xsl:template match="global-instance">
    <xsl:for-each select=".//*[contains(@id,'_error_message')]">
         <myErrorTest><xsl:value-of select="."/></myErrorTest>
    </xsl:for-each>
</xsl:template>
