【问题描述】：

我想使用 XSLT 删除具有特定子元素和特定文本的元素。用例：我想从 Mavon pom.xml 文件中删除一个插件。

假设（删节的）Maven pom.xml 的 XML 如下：

如何删除maven-shade-plugin 插件？这意味着我需要删除plugin 节点，该节点有一个名为artifactId 的子节点（可能是第一个、第二个或第n 个子节点），其文本为maven-shade-plugin。

这会给我留下以下 XML：

我已经阅读了 Removing XML Nodes using XSLT 和 Use XSLT/XPATH to select elements having a child element with a specific value 并认为这样的东西可以解决问题，但还没有设法将它们组合在一起。

非常感谢。托马斯。

P.S.：这个问题不是关于 Maven 或其最佳实践，而是关于 XML/XSLT/XPATH。

【问题讨论】：

标签： xml xslt xpath

【解决方案1】：

啊……似乎命名空间是问题所在：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:pom="http://maven.apache.org/POM/4.0.0">
<xsl:output method="xml" indent="yes"/>
<xsl:strip-space elements="*" />

<xsl:template match="@*|node()">
 <xsl:copy>
  <xsl:apply-templates select="@*|node()"/>
 </xsl:copy>
</xsl:template>

<xsl:template match="pom:plugin[pom:artifactId='maven-shade-plugin']" />

</xsl:stylesheet>

似乎可以解决问题... ...抱歉浪费了您的时间。
