Question

I was wondering if it is possible to write a python regex to match it up with any valid English sentence which can have alphanumeric characters and special characters.
Basically, I wanted to extract some specific elements from an XML file. These specific elements will have the following f或m:

<p o=<Any Number>> <Any English sentence> </p>

例如:

<p o ="1"> The quick brown fox jumps over the lazy dog </p>

或

<p o ="2">  And This is a number 12.90! </p>

We can easily write regex f或

<p o=<Any Number>>

和标签。但我有兴趣通过写入 Regex 组来提取这些标签之间所隐藏的句子。

Can anyone please suggest a Regex to be used f或 the problem above?

Also, if you can suggest a w或karound approach, then it will be really helpful to me as well.

Answer 1

Use an XML parser like lxml, regex is not suitable for this task. Example:

import lxml.etree
// First we parse the xml
doc = lxml.etree.fromstring( <p o ="2">  And This is a number 12.90! </p> )
// Then we use xpath to extract the element we need
doc.xpath( /p/text() )

您真的应该使用 xml 剖析器。这里的示例 < href=" http://www.travisglines.com/web-coding/python- xml-parser-tutial" rel=“ no follow” > http://www.travisglines.com/web-coding/python- xml-parser-tutial 。
