Question

我有xml文件，它为游戏和dlc使用两个命名空间。我现在正在尝试将简单的xls转换为html作为表格。但我无法让它工作，我已经解决了问题，它必须是名称空间。 html总是空白的，只有表头。我100％确定模式是否有效，因为xml验证不会产生任何错误。

xml文件：

Answer 1

阅读有关XML命名空间的一些教程，已经在stackoverflow.com上询问并回答了很多。

在XML输入中有一个声明为xmlns="http://www.steamkauppa.fi/game"的默认命名空间，这意味着输入中所有未加前缀的元素都属于该命名空间。

为了能够对这些元素进行XSLT转换，将命名空间添加到XSLT中：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:game="http://www.steamkauppa.fi/game" exclude-result-prefixes="game">

既然在你的XSLT中声明了名称空间，你应该使用它，参见下一个调整：

<xsl:for-each select="game:GameStore/game:Game">
<xsl:value-of select="game:Name"/>

完全调整的XSLT：

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:game="http://www.steamkauppa.fi/game" exclude-result-prefixes="game">

<xsl:template match="/">
  <html>
  <body>
  <h2>My CD Collection</h2>
    <table border="1">
      <tr bgcolor="#9acd32">
        <th style="text-align:left">Name</th>
        <th style="text-align:left">Category</th>
      </tr>
      <xsl:for-each select="game:GameStore/game:Game">
      <tr>
        <td><xsl:value-of select="game:Name"/></td>
        <td><xsl:value-of select="game:Category"/></td>
      </tr>
      </xsl:for-each>
    </table>
  </body>
  </html>
</xsl:template>
</xsl:stylesheet>

使用两个名称空间将XSL转换为HTML
