REGEX to get href="#"

monfu · March 11th, 2008, 07:29 AM

Dear All,

I have an href, for example <a href='http://www.google.com'>google</a>, and I need to strip it off to make it unclickable, so I wish for it to be replaced by <a href='#'>google</a>.

Can you suggest me a RegEx pattern to achieve this, since I am not very good with RegEx's.

Thanks

Regards

Johann

So you want a regexp that fits something like this:

Code:

<a href="http://www.example.com/example/url.html">

You could try

Code:

<a href=["']*[^>"']+["']*>

the square brackets means any character, the ^ means "negation" and the > and " are the two characters you don't want inside.

In perl this would work most of the time:

Code:

s/(a href=")[^"](")/$1#$2/g;

So:

Code:

charlie:~$ perl -ne 's/(a href=")[^"]+(")/$1#$2/g;print;'
<a href="GOOGLE.COM">google</a> <a href="http://charlieharvey.org.uk">my homepage</a>
<a href="#">google</a> <a href="#">my homepage</a>
charlie:~$
