我是 XML - XSLT 转换的新手。我有以下XML文件和相应的XSLT文件，但由于某种原因，它没有显示任何通过h2的内容，这是一个HTML。任何帮助都会很棒！
我已经检查了命名空间以确保它与 XML 文档匹配，并且我还尝试在 W3 站点上运行代码。
两个文件如下：

XSLT
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"/>
<xsl:template match="/">
<html>
<body>
<h2>Alphaba Resume - Long version</h2>
<xsl:for-each select="alphabafictional_resume/objective">
<h2><xsl:value-of select="objective"/></h2>
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
您提到您已经"检查了命名空间以确保它与 XML 文档匹配"，但 XSLT 中根本没有对命名空间"https://swe.umbc.edu/~asacko1/xs"的引用。
在 XML 中，"https://swe.umbc.edu/~asacko1/xs"是默认命名空间。在 XSLT 1.0 中，处理这些问题的方法是使用命名空间前缀声明它，并在整个 XSLT 中使用该前缀。
试试这个 XSLT
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:swe="https://swe.umbc.edu/~asacko1/xs">
<xsl:output method="html"/>
<xsl:template match="/">
<html>
<body>
<h2>Alphaba Resume - Long version</h2>
<xsl:for-each select="swe:alphabafictional_resume/swe:objective">
<h2><xsl:value-of select="swe:obj_body"/></h2>
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
请注意，此处前缀 (swe( 的选择是任意的。它可以是任何东西，只要命名空间 URI 匹配即可。
如果可以使用 XSLT，则在默认命名空间方面情况会稍微简单一些，因为您可以使用xpath-default-namespace代替，而不必担心添加前缀：
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xpath-default-namespace="https://swe.umbc.edu/~asacko1/xs">
<xsl:output method="html"/>
<xsl:template match="/">
<html>
<body>
<h2>Alphaba Resume - Long version</h2>
<xsl:for-each select="alphabafictional_resume/objective">
<h2><xsl:value-of select="obj_body"/></h2>
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
您正在循环访问objective元素，并尝试在每个元素中输出另一个objective元素的值，但没有。你应该在做
<xsl:value-of select="obj_body"/>
相反？
我的 XSL 将负责将输出转换为 <h2> 标记的文本。XSL 更加灵活，以防有人在简历中的某个位置嵌入您意想不到的目标。
<xsl:for-each select="//*[name()='obj_body']">
<h2><xsl:value-of select="."/></h2>
</xsl:for-each>
我之所以使用 name()，是因为命名空间没有很好地定义，因此需要将其评估为字符串obj_body因此需要评估。
