Question

我有多级深度XML（非常抱歉长篇例），各级别的节点包含错误消息。这些节点都具有以“_error_message”结尾的属性@id。我试图通过XSLT select将所有这些错误收集到一个平面列表中，但由于某种原因，select只找到两个这样的节点，根本无法得到它们的文本。我做错了什么？

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>

contains的论点是错误的，而select只关注global-instance的直接孩子，而不是更深层次的后代。

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