Question

我试图通过XSLT复制xml，并且源XML中的CSS被放置在xhtml xml文件的主体中，并且head元素看起来是空的。如何在正确的位置获取CSS引用，以便格式化新创建的XML文件。

源XML

XSL

       xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
       xmlns="http://www.w3.org/1999/xhtml"
       >

       <xsl:output method="xml" />


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



      <xsl:param name="albumid">SUBL</xsl:param>
       <xsl:template match="/">
         <html> 
         <body>
          <xsl:apply-templates/>
         </body>
         </html>
       </xsl:template>
       <xsl:template match="music_inventory">

       </xsl:template>

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

         </a>
        </id>
       </xsl:template>

    </xsl:stylesheet>

生成的XML（注意样式表引用的位置）

Answer 1

匹配/的模板存在问题。您可以使用此样式表：

<xsl:stylesheet  version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/xhtml" >
    <xsl:output method="xml" />
    <xsl:template match="node() | @*">
        <xsl:copy>
            <xsl:apply-templates select="node() | @*"/>
        </xsl:copy>
    </xsl:template>
    <xsl:param name="albumid">SUBL</xsl:param>
    <xsl:template match="/">
        <xsl:apply-templates select="processing-instruction()"/>
        <html>
            <body>
                <xsl:apply-templates select="*"/>
            </body>
        </html>
    </xsl:template>
    <xsl:template match="music_inventory">
        <xsl:apply-templates select="album[@id=$albumid]"/>
    </xsl:template>
    <!--creates hyperlink-->
    <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>

Answer 2

head元素显示为空。

输出中没有头元素。如果你想要一个头部元素，你必须创建它 - 如果你不想让它成为空的，你必须把它放进去。

例如，你可以这样做：

<xsl:template match="/">
    <html> 
        <head>
            <xsl:copy-of select="processing-instruction('xml-stylesheet')" />
        </head>
        <body>
            <xsl:apply-templates select="music_inventory/album[@id=$albumid]"/>
        </body>
    </html>
</xsl:template>

这会在输出文档中创建一个head部分，并将链接到样式表的处理指令复制到其中，而不做任何更改。

这对你来说不是很清楚。我认为你的样式表存在许多问题，这些问题与你当前的问题无关，而我现在还没有时间进入。结果，很难说出你想要最终得到的结果究竟是什么，以及这样的结果是否对任何事物都有用。

XSL转换为包含css
