Question

Regex to fix URL structure /duplication issue

Asked by: MichaelEvangelista

I have some ColdFusion code that creates a google sitemap from the urls in any website's links, compiling the base URL onto the link 'href' attribute. It works great except for 'absolute' links, where i get
www.thesite.com/somefolder//somefolder/somepage.html  

What I need is a regex that will look for this pattern

/string//string/

and replace it with

/string/

in any url where 'string' is any folder name (text string)

s#/(.*)//\1/#/$1/#g;

 

by: MichaelEvangelistaPosted on 2009-06-25 at 14:57:16ID: 24716414

Thanks - but I'm not clear on how to use this.

<cfset theurl = "www.thesite.com/somefolder//somefolder/somepage.html">
<cfset cleanurl = rereplace(theurl,'s##/(.*)//\1/##/$1/##g;','','all')>

( for CF I have to replace # with ## to get a single escaped hash mark)

The output should be
' www.thesite.com/somefolder/somepage.html '

where the regEx finds 'somefolder//somefolder' but selects just the first part  
i.e.  ' somefolder // ' including the two //

which i replace with
'' (null)


So what i actually need is the regex that will identify
'string//string'
and select just the first part, 'string//' , for deletion

thanks//thanks
