Regex help! - Visual Basic .NET

Rob

Hi,
I've written a small VB application that parses an HTML document and
removes code I don't need and re-writes the file. I'm looking for the
regex pattern that will remove the following code:

<head>
<meta http-equiv=Content-Type content="text/html; charset=windows-1252">

<title>T1 CRR Online Manual</title>
<style>

</style>
</head>

...of course the page continues after the </headtag but I want to
remove everything within the head tags including the head tags. This has
to work on any HTML file that I parse so the contents within the head
tags may be different. This is what I've got so far:

pattern = "<head>[.|\s|\n]*<\/head>"
returntext = Regex.Replace(r eturntext, pattern, "")

...but this doesn't work. Anyone out there with a solution?

Thanks
Rob

How about:

Regex.Replace(r eturnText, "<head>.*</head>", "",
RegexOptions.Si ngleline)

Thanks,

Thanks Seth,

That works...but only with the RegexOptions.Si ngleLine parameter. I
didn't have that before.

That because the singleline option tells the period to also match the
newline character.

Thanks,

Regex help, please - Recognize quoted strings?

by: Dave | last post by:

I'm struggling with something that should be fairly simple. I just don't know the regext syntax very well, unfortunately. I'd like to parse words out of what is basically a boolean search string.

I'd like to use Regex to pull out the words, or the phrases if the words are enclosed in quotes....

Regex doesn't match when test string is in middle of file

Hi Everyone, I am using a regex to check for a string. When all the file contains is my test string the regex returns a match, but when I embed the test string in the middle of a text file a match is never returned.
