Simple regex to remove an attribute

Hey guys,

I'm really really suck in PHP using preg_replace.

I have some XML, which goes a little like this:

att1="xyz" att2="uio"
att3="qwerty"

where I want to remove the second attribute all together.

Ideally I'd just like to grab everything form
"att2" to "att3" and
replace it with just "att3". I thought that would
be a fairly simple
thing to select, but apparently not.

I've tried this:
[(att2)^(att3)] but it doesn't seem to work at all.

Any help would be really appreciated.

Cheers,
-F

Hi F,

Sample text:
att1="xyz" att2="uio"
att3="qwerty"
att1="xyz" att2="bac"
att3="qwerty"
att1="xyz" att1="uio"
att3="qwerty"
att1="xyz" att2="xyz"
att3="qwerty"
att1="xyz" att2="uio"
att3="qwerty"  att3="qwerty"
att1="xyz" att2="cba"
att3="qwerty" att4="qwerty"
att3="qwerty"

Pattern:
(att2=['"][^'"]*['"]s*)att3=

Match $1
att2="uio" att3= att2="uio"
att2="bac" att3= att2="bac"
att2="xyz" att3= att2="xyz"
att2="uio" att3= att2="uio"
att2="cba" att3= att2="cba"

Again, I am assuming att* may be repeated and NOT that ' or
" are
included in your expressions. Ex: att2="O'Donnell"
will return a false
match.

Thanks!
Syd
