Why are you attaching after the last meta tag - wouldn't it be easier just before the </head> tag or just after the <head> tag - you should have no other js in the header - except possibly an HTML 5 shim...

Is there a way to make a 2 pass substitution? 1st one removing all the \n's and then using another one to substitute the string that I want?

Hi Jason,

I tried it:

Substitute "s%(<meta [^>]*>).*?$%$1<script>window['start-time'] = new Date().getTime();window['app-key'] = \"xxx\";</script><script src=''></script>%i"

However it still replaces each line that the meta tag appears on.

Hi Jason,

Each meta tag is appearing on a separate line. Will it work even then? Trying it out any ways.

Thanks,

Mayuresh

Hello,

According to the Apache Glossary page, it’s all PCRE based. So you should be able to use the “non-greedy” match. So instead of .* which will match all instances, use .*?. If you anchor it at the end of the string, something like (text you are matching against).*?$, then you can be certain of getting the last one.

Hi,

How can I check for the last occurrence of a string in the response html and only replace the last occurrence of it?

I want to search for the last "meta" tag in the response and replace it with something.

How can I do this?

Thanks,

Mayuresh
