Question

我是XML和XSLT的新手。我正在尝试做的是一个XSLT转换，它匹配我的XML文档中的任何元素类型相册/名称，并将它们的值转换为链接。到目前为止，我所做的一半是其中的一半。我很难理解如何获得链接。任何关于如何实现这一点的建议都将受到赞赏。

编辑：使用xsltproc -o new_inventory.xml music_inventory.xsl music_inventory.xml和下面的XML和XSLT，它似乎是按照我的意愿放入链接，但是当我尝试从浏览器查看时，我收到文档为空的错误消息。

这是由上面的命令创建的new_inventory.xml。（注意任何元素周围没有XML标签接受链接。）

<?xml version="1.0"?>

XSLT

   <xsl:template match="album/name">
    <id>
     <a xmlns="http://www.w3.org/1999/xhtml"
      href="{../@id}.xhtml">
       <xsl:value-of select="."/>
     </a>
    </id>
   </xsl:template>

Answer 1

注意任何元素周围没有xml标签接受链接

如果您将身份转换添加到XSLT，

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

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

  <xsl:template match="album/name">
    <id>
      <a xmlns="http://www.w3.org/1999/xhtml"
         href="{../@id}.xhtml">
        <xsl:value-of select="."/>
      </a>
    </id>
  </xsl:template>

</xsl:stylesheet>

您将获得缺少的XML标记以及链接：

为什么我的XSLT转换会丢弃大多数XML标记？
