PHP to remove xml

Question

I need some help with a problem if possible.

<IndexFile index="dlc:blahblahblahblah.zip" version="1.19.0" />

How would I use php to remove everything in the above line of code except

blahblahblahblah.zip

Note: blahblah isn't actual name, the name changes; I just need to remove the xml on either side of the .zip file.

I've tried a few things like strip_tags() but nothing works up to now.

can you provide actual xml that you want to remove. This information is insufficient for providing answer — Alankar More, Mar 11 '16 at 06:57
By using `preg_quote` on your `$find` variable you ruin any regex in it and every character will be considered that exact character (including `(.+?)`) — h2ooooooo, Mar 11 '16 at 08:12
@unknown1 You can still use `preg_quote`, just don't use it on stuff you want to regex. `$pattern = '/^.*' . preg_quote('index="dlc:', '/') . '(.+?).*$/m'`; — h2ooooooo, Mar 11 '16 at 08:41

Your test string was <IndexFile index="dlc:blahblahblahblah.zip" version="4.19.0" />

Your regex pattern should be : index="dlc:(.+?)".

Your answer is: blahblahblahblah.zip

Ideally, you have to use an XML parser to parse the file and use XPaths/looping to get that item.

If that is the only line, why can't you just use a Regex to extract the value? index="[a-zA-Z0-9_.-:]*" (or [a-zA-Z0-9_.-:]*.zip)?

Again, you need to think about the future impacts.
