对，需要修改代码，不过道理是相同的。把代码中原来提取method的关键词替换成你下次要提取的关键词就可以了。

你好，我很想知道，你的文本有什么特点，为什么第一次提取失败了？做了什么调整后又成功了，以后大家好都注意下，呵呵。

同一个文件中有多个 <method>blah blah blah</method> 的内容，所以修改了 Regular Expression 以进行匹配。

The quantitifier * in regular expressions is "greedy" - in this case the pattern .* will include everything between the first instance of <method> and the last instance of </method>. You can use a question mark to limit it - .*?

文本就是最简单的xml格式，只是一个文件里同一格式出现多次。至于怎样调整的，本人菜鸟得很，楼上专家们在讨论。共勉啊

- First, download and install Python Interpreter, if you don't have one.
- Download the pyXML.zip (attached); unzip it and put in the same folder as your xml files.
- Double click the script (pyXML.py) and a report will be generated containing the content you need.

好用就好。Python 语法简洁一些，下面这两本书都是入门的好教材：

Haiyang，刚刚试过，很好用，如果想检索其它项也都成功，不胜感激！帮我这么大忙，真是应该请客啊。
Python的语言好像不那么令人生畏，很想学习一下，请问哪里能找到通俗易懂又和语料库有关系的材料呢？
