刚接触XSL 请帮我看看这个XMl文档的xsl
小弟刚接触XSL 不知道对于结构比较复杂的XMl文档，该怎么编写xsl。举个小例，我不知道对应于不同的<title>标签里的A、B、C，怎么输出<ptTopContent>中的内容（title中的A下输出A:warning_1、A:(1)caption_1、A:para_2等，title中的B下输出B:(1)caption_4，以此类推）请大神明示，最好代码说话
我的XML 源文件
我写的对应的XSL，文件名：xsl-1 ，请问是哪里出错了
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="xsl-1.xsl" type="text/xsl"?>
