所以我的问题是，我已经提取了很多论坛帖子到单独的txt文件，现在在我的硬盘上。每个文件都包含我想要提取的信息，其中一些我已经计算出如何提取。我需要提取的信息是以下形式：如何从HTML文件中提取特定内容为TXT格式？
在相同的“HTML块”
1：（X）在该线程消息
2：消息是答复（一些HTML代码） A HREF =“链接”（一些HTML代码=
在任务1是简单地需要提取X
在任务2 I需要提取该消息是答复
我已经看过的链接到不同的tm和XML包中，但一直未能实现找出要使用的东西。任何建议表示赞赏。
这就是txt文件的一个看起来像

<TR BGCOLOR="#F0F0F0"><TD ALIGN=LEFT NOWRAP><TT>I was using Lego Digital Designer and am disappointed the downhill availabilty<BR>
of certain important parts to build "buyable" models.<BR>
<BR>
I would like to see a return of "warehouse" sliding doors to make<BR>
box cars.<BR>
<BR>
Train-style doors would also be nice as well as train windows (both in<BR>
2x3 and 4x3)... please.<BR>
<BR>
I looked at the instructions to build a mail car from the 7722, and<BR>
found that I really only need 2 red sliding rail doors, the pair of<BR>
"decorated train doors" and a set of two 2x3 thin yellow train<BR>
windows.<BR>
<BR>
Yes, there was a bit of minor substitution but it is mostly distiguishable<BR>
as the model.<BR>
<BR>
Here is what it looks like:<BR>

Yeah I know... where are the f-in doors???<BR>

我建议XML包。请提供一些示例代码。 – sgibb
所以我想，如果可以构建一段代码，可以检测到“消息在答复：”，然后采取下一个A HREF =“链接”...？ –
我在您提供的html中没有看到“此线程中的消息”。请编辑您的问题，并添加相关的html代码 – GSee
