XSLT删除XML指定属性与元素失败，请求技术协助

需要修改XML文件，删除指定元素和属性，但当前XSLT无法选中目标元素。

原始XML #

需求 #

• 删除feed元素中的xml:base属性
• 删除feed和entry下的id元素

当前无效的XSLT #

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="node()|@*">
    <xsl:copy>
        <xsl:apply-templates select="node()|@*"/> 
    </xsl:copy>
</xsl:template>
<xsl:template match="@xml:base"/>
<xsl:template match="feed/id"/>
<xsl:template match="feed/entry/id"/>
</xsl:stylesheet>

问题根源在于XML的命名空间：原始XML中的feed、id、entry等元素都属于http://www.w3.org/2005/Atom命名空间，但原XSLT未声明该命名空间，导致模板无法匹配目标元素。

修改后的有效XSLT如下：

<xsl:stylesheet version="1.0" 
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:atom="http://www.w3.org/2005/Atom">
  <!-- 身份模板：默认复制所有节点和属性 -->
  <xsl:template match="node()|@*">
    <xsl:copy>
        <xsl:apply-templates select="node()|@*"/> 
    </xsl:copy>
  </xsl:template>

  <!-- 删除xml:base属性 -->
  <xsl:template match="@xml:base"/>

  <!-- 删除feed下的id元素 -->
  <xsl:template match="atom:feed/atom:id"/>

  <!-- 删除entry下的id元素 -->
  <xsl:template match="atom:feed/atom:entry/atom:id"/>
</xsl:stylesheet>

关键修改说明 #

1. 声明命名空间：在xsl:stylesheet标签中添加xmlns:atom="http://www.w3.org/2005/Atom"，为Atom命名空间指定前缀atom。
2. 前缀匹配元素：所有匹配feed、id、entry的模板都需添加atom:前缀，确保匹配到命名空间下的目标元素。
3. xml:base属性无需前缀：xml:是内置命名空间，直接match="@xml:base"即可生效。
