Using REGEX to harvest links in HTML

[Rottingham]

Hello

 

I have a replace_links() function that searches HTML source and harvests all the links into an array. I'm finishing eNewsletter software and have a few last bugs to work out.

 

My regex is:

if( !preg_match_all("/<a\s[^>]*href=(\"??)([^\" >]*?)\\1[^>]*>(.*)<\/a>/siU", $template_source, $matches, PREG_SET_ORDER ) ) {
	echo "      Failed to find any matches using regex: /<a\s[^>]*href=(\"??)([^\" >]*?)\\1[^>]*>(.*)<\/a>/siU.<br>";
	return;
}

 

This works beautifully! I then add some code to change the link to point to a click tracker and insert it back into the HTML.

 

My dilemma is that if the link includes any white spaces the regex fails. IE if I did a mailto link like this:

 

<a href="mailto:[email protected]?subject=Thanks for visiting">Mail me</a>

 

The regex fails. If I place any character in the whitespace, like an underscore it works fine. How can I include whitespace in that regex line? I'm not very good at this stuff!

 

Thanks for any help.

There's a space in your negative character class that's preventing the regex from matching when there is a space (I put a red X where the space is):

 

"/<a\s[^>]*href=(\"??)([^\"X>]*?)\\1[^>]*>(.*)<\/a>/siU"
