Regular Expressions to parse HTML

Guest · May 2, 2006

I need to parse and HTML document of the following format.

I am interested to obtain all the HTML from and including the first <div
class="data"> up to and including Data updated dd/mm/yyyy (where dd/mm/yyyy
will change). what kind of regular expressions can I use? Note I want
everything in the core of the HTML including all the tags within the div tags.

<html>
<head>

</head>
<body>
<div class="head">not interested in this</div>
<div class="data">Interested in data from this first data div</div>
<div class="data">There can be <b>other tags</b> within these divs too!</div>
<a name="data3"></a>(There can be some other stuff in between the div tags)
Data updated dd/mm/yyyy
<img src="notInterested.jpg">
some other rubbish
<div class="footer">not interested</div>

Treating the input Html as one string (C# code):

Regex regex = new Regex(@"(<div class=""data"">.*(?=<img))",
RegexOptions.Singleline);

Sample input:
<html>
<head>

</head>
<body>
<div class="head">not interested in this</div>
<div class="data">Interested in data from this first data div</div>
<div class="data">There can be <b>other tags</b> within these divs too!</div>
<a name="data3"></a>(There can be some other stuff in between the div tags)
Data updated dd/mm/yyyy
<img src="notInterested.jpg">
some other rubbish
<div class="footer">not interested</div>

Sample output:
1 =Â»<div class="data">Interested in data from this first data div</div>
<div class="data">There can be <b>other tags</b> within these divs too!</div>
<a name="data3"></a>(There can be some other stuff in between the div tags)
Data updated dd/mm/yyyy
