Regex Request: Extract link href value and link display text
Nate Covington
Nate Covington
This is what I'm starting with - find:
Replace:
<a href="\1" onclick="ga('send','event', {'eventCategory': 'Button','eventAction': 'Click', 'eventLabel':'\1'});"
I want to replace "eventAction=Click" with the text of the actual link.
Something more like find:
Replace:
<a href="\1" onclick="ga('send','event', {'eventCategory': 'Button','eventAction': '\2', 'eventLabel':'\1'});">\2
Where "\2" is my magic variable for the actual visible link text - what appears before </a>
And the tricky part is sometimes my links are structured like this:
<a href="/url" onclick="ga('send','event', {'eventCategory': 'Button','eventAction': 'Click', 'eventLabel':'/url'});"><span class="orange"><span style="text-decoration: underline;"> link text here</span></span></a>
Thanks!

Can you give a few examples of the full before HTML of the links you have and after HTML you want?
And do you want this added on every single link in your website? What happens to links that already have an onclick?

Sure, here's a messy one, before:
<a href="/article-url-here"><span class="orange"><span style="text-decoration: underline;">link text here</span></span></a>
After:
<a onclick="ga('send','event', {'eventCategory': 'Button','eventAction': 'link text here, 'eventLabel':'/article-url-here'});" href="/article-url-here"><span class="orange"><span style="text-decoration: underline;">link text here</span></span></a>
And a cleaner one - before:
<a href="/article-url-here">link text here</a>
After:
<a onclick="ga('send','event', {'eventCategory': 'Button','eventAction': 'link text here, 'eventLabel':'/article-url-here'});" href="/article-url-here">link text here</a>

Ok, and what about links with classes and other attributes? Should they also be done?
What about links with other tags inside, like strong and em and images?

It all makes the regex very complex for this kind of thing...

Other link classes should be okay, it should process those. Can it skip any links that already has an "onclick"? For now let's make it only apply to text images, anything with an image can be skipped too. Whatever makes this easy is a good place to start, from my angle.

Something like this:
<a href="[^"]*)">((?:<span[^>]*>)*([^<]+?)(?:</span>)*)</a> Replace with:
<a href="\1" onclick="ga('send','event', {'eventCategory': 'Button','eventAction': '\3', 'eventLabel':'\1'});">\2</a>

Hmm, that doesn't seem to be firing.

Can you write it so it targets just the "clean" version, ignore the spans and nested junk?
If we could get it working just for this - before:
<a href="/article-url-here">link text here</a>
After:
<a onclick="ga('send','event', {'eventCategory': 'Button','eventAction': 'link text here, 'eventLabel':'/article-url-here'});" href="/article-url-here">link text here</a>

Sorry, I was missing a parenthesis:
<a href="([^"]*)">((?:<span[^>]*>)*([^<]+?)(?:</span>)*)</a>
