如何在文本文件中打印某些行和某些行的部分(How to print certain lines and certain parts of line in a text file)

我正在尝试从HTML文件中提取信息（导出的Google Chrome书签）

它包含以下格式的文本，我想在<DT><A HREF=和ADD_DATE=之前提取网站地址

我正在考虑使用SED和AWK或Python因此欢迎来自三种语言的任何答案

到目前为止，我只知道如何使用awk打印包含<DT><A HREF=

awk '/<DT><A HREF="*"/' favorit.html

我想我应该把它与sed结合起来

I'm trying to extract information from an HTML file(Google Chrome Bookmarks exported)

It contains text of the following format and I would like to extract just the website adresses after <DT><A HREF= and before ADD_DATE=

I'm considering using SED and AWK or Python So any answers from the three languages are welcome

So far I just know how to print lines containing <DT><A HREF= with awk

awk '/<DT><A HREF="*"/' favorit.html

i suppose i should combine this with sed

最满意答案

一个非常快速的解决方案是在Python中使用正则表达式。

假设变量s包含您的HTML字符串：

import re s = ''' <DT><A HREF="http://gmazars.info/conf/index.html" <DT><A HREF="http://research.google.com/" <DT><A HREF="http://research.microsoft.com/en-us/" <DT><A HREF="http://techresearch.intel.com/articles/index.html" ''' print re.findall("HREF=\"(.*?)\"", s)

A very quick solution would be to use regular expressions in Python.

Assuming that the variable s contains your HTML string:

import re s = ''' <DT><A HREF="http://gmazars.info/conf/index.html" <DT><A HREF="http://research.google.com/" <DT><A HREF="http://research.microsoft.com/en-us/" <DT><A HREF="http://techresearch.intel.com/articles/index.html" ''' print re.findall("HREF=\"(.*?)\"", s)
