从带有XML的XML文件中提取条目列表

我做错了什么。这是一个显示问题的示例XSL文件：

<?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" indent="yes" version="4.01"
    doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
    doctype-public="//W3C//DTD XHTML 1.0 Transitional//EN"/>
  <xsl:template match="/">
    <html xmlns="http://www.w3.org/1999/xhtml">
      <head>
        <meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
        <!--<link rel="stylesheet" type="text/css" href="Workbook-off.css"/>-->
        <title>Custom Report</title>
      </head>
      <body>
        <xsl:variable name="AssignHistory" select="document('AssignHistory.xml')"/>
        <xsl:for-each select="$AssignHistory/AssignmentHistory/*/Items/Item[@Name='Name1']">
          <xsl:apply-templates select="Item"/>
        </xsl:for-each> 
      </body>
    </html>
  </xsl:template>
  <xsl:template match="Item">
    <xsl:variable name="datestr" select="name(../..)" />
    <p>
      <xsl:value-of select="substring($datestr, 8, 2)"/>
      <xsl:text>/</xsl:text>
      <xsl:value-of select="substring($datestr, 6, 2)"/>
      <xsl:text>/</xsl:text>
      <xsl:value-of select="substring($datestr, 2, 4)"/>
      <br/>
      <xsl:value-of select="Theme"/>
      <br/>
      <xsl:value-of select="Method"/>
      <br/>
    </p>
  </xsl:template>
</xsl:stylesheet>

这是XML数据：

<?xml version="1.0" encoding="UTF-8"?>

            </Item>

    <W20160111>

            </Item>
            <Item>
                <Name/>
                <Theme>Prepare This Month’s Presentations</Theme>

            </Item>
        </Items>
    </W20160111>
</AssignmentHistory>

最后我会把它整理成一张桌子。但当时我还以为它能拿出两个参赛作品。没有显示任何内容。

我的xpath好像有问题。

这里的问题是：

<xsl:for-each select="$AssignHistory/AssignmentHistory/*/Items/Item[Name='Name1']">

将您置于Item的上下文中。在此背景下：

<xsl:apply-templates select="Item"/>

不选择任何内容，因为Item不是其自身的子级。

最简单的解决方案是更换：

<xsl:for-each select="$AssignHistory/AssignmentHistory/*/Items/Item[Name='Name1']">
    <xsl:apply-templates select="Item"/>
</xsl:for-each>

带有：

<xsl:apply-templates select="$AssignHistory/AssignmentHistory/*/Items/Item[Name='Name1']"/>

我想$AssignHistory/AssignmentHistory/*/Items/Item[@Name='Name1']应该是$AssignHistory/AssignmentHistory/*/Items/Item[Name='Name1']。
