如何解析XSLT中CDATA元素内的XML DOM?

问题描述

说我有一个XML文件，例如:

say I have an XML file like:

<library>
 <books>
  <![CDATA[<genre><name>Sci-fi</name><count>2</count></genre>]]>
  <book>
   <name>
    Some Book
   </name>
   <author>
    Some author
   </author>
  <book>
  <book>
   <name>
    Another Book
   </name>
   <author>
    Another author
   </author>
  <book>
 <books>
</library>

我想在xslt转换器中读取CDATA元素名称"，并将其值放置在标签的值中.我该怎么做呢?AFAIK，我们不能在CDATA的内容上使用xpath.是否有一些破解/解决方法?我想在XSLT中严格执行此操作.

I want to read the CDATA element 'name' in an xslt transformer and place its value somewhere in the vaue of a tag. How do I do this? AFAIK, we cannot use xpath on the contents of CDATA. Is there some hack/workaround for this? I want to do this strictly in an XSLT.

推荐答案

由于CDATA块是文本节点(的一部分)，因此您可以提取两个标签"之间的文本，例如像这样:

Since CDATA blocks are (part of) text nodes, you can extract the text between the two "tags", e.g. like this:

<xsl:template match="text()">
  <xsl:value-of select="substring-before(substring-after(., '&lt;name>'), '&lt;/name>')"/>
</xsl:template>

这只是一个简单的想法.如果CDATA中有多个名称元素"，则只需递归地多次应用上述表达式即可.

This is just a quick idea. If you have more than one name "element" inside the CDATA, just recursively apply the above expression multiple times.
