hi all.

I have a problem that I think cn be solved with a bit of regex code, only I do not know enough to work this one out

example:
I have a string something like:

[CODE] <p><x>yz</x>someRandomText</p><p>moreTextThenAnother<x>yz</x>thenEvenMoreText</><p>rinseAndRepeat</p>[/CODE]

I need to search through the string , extract the yz do some stuff to it and then put it back between the x tages, so the string ends up like

[CODE] <p><x>qyzq</x>someRandomText</p><p>moreTextThenAnother<x>qyzq</x>thenEvenMoreText</><p>rinseAndRepeat</p>[/CODE]

does anyone know how I would do this? thanks

@tastroSep 21.2011 — echo preg_replace("@(<x>)(yz)(</x>)@ism",'$1q$2q$3','<p><x>yz</x>someRandomText</p><p>moreTextThenAnother<x>yz</x>thenEvenMoreText</><p>rinseAndRepeat</p>');

also insert here what you want instead of the two qq in $1q$2q$3

I'm not sure this is going to work. the <x>yz</x> may some times be <x>abc</x>, an unknown value, so it needs to find , processes and replace what is between the <x> tags , will this do that or does it just search for a set value?

Success!
