正则表达式解析HTML [英] Regular Expression to Parse HTML

问题描述

有没有人有正则表达式模式来解析流中的HTML？


我有一个结构良好的文件，其中每一行都是


< sometag someattribute =''attr''> text< / sometag>


例如


< SPAN CLASS =''myclass''>一些文字< / SPAN>，或

只是一些文字，没有标签


我想要什么能够做的是解析每一行，这样我得到一个数组

这样的


SPAN

CLASS

myclass

一点文字


或


只是一些文字，没有标签


数组位应该跟随，但我不是自称是一个正则表达式专家（或者

任何类型的专家）。任何人都可以帮助一个合适的

模式吗？


TIA

Hi Galin


感谢您的链接。它看起来应该可以工作，但是当我测试它时，即使是一个简单的标签它也不会返回
，它不返回任何匹配项。我尝试用Expresso验证

表达式，它给出了以下错误。


参考未定义的组号5.


即使我使用网站上的设施测试它也会失败。任何想法

如何纠正它？

Does anyone have a regex pattern to parse HTML from a stream?

I have a well structured file, where each line is of the form

<sometag someattribute=''attr''>text</sometag>

for example

<SPAN CLASS=''myclass''>A bit of text</SPAN>, or
Just some text, without tags

What I would like to be able to do is parse each line so that I get an array
like this

SPAN
CLASS
myclass
A bit of text

or

Just some text, without tags

The array bit should follow, but I don''t profess to be a regex expert (or
any kind of expert for that matter). Can anyone help with a suitable
pattern?

TIA

Charles

Maybe it''s easier to use the HTML Agility Pack:

Hi Galin

Thanks for the link. It looks like it ought to work, but when I test it
against even a simple tag it returns no matches. I tried verifying the
expression with Expresso and it gives the following error.

Reference to undefined group number 5.

Even when I test it using the facility on the web site it fails. Any idea
how to correct it?
