Question

我不知道为什么我的for-each声明不起作用。我检查了其他帖子，但我找不到原因。如果有人可以帮助我？
这是我的xml文件：

<?xml version="1.0" encoding="utf-8" ?>
<?xml-stylesheet type="text/xsl" href="Student.xslt"?>
<students xmlns = "urn:students">
  <student>
    <name>Pesho</name>
    <sex>Both</sex>
    <birthdate>1990-01-01</birthdate>
    <phone>0888112233</phone>

这是xslt文件：

Answer 1

这是名称空间问题。

将urn:students的名称空间前缀声明添加到样式表中：

<xsl:stylesheet version="2.0"
                xmlns:s="urn:students"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

然后在xsl:for-each/@select XPath：

中使用它

       <xsl:for-each select ="/s:students/s:student">

对样式表中的所有XPath执行此操作。

为什么for-each不能在我的xslt文件中工作
