Answer 1

When your regex processor doesn't support variable length look behind, try this:

(<.+?>[^<>]*?)(_mystring_)([^<>]*?<.+?>)

Preserve capture groups 1 and 3 and replace capture group 2:

For example, in Eclipse, find:

(<.+?>[^<>]*?)(_mystring_)([^<>]*?<.+?>)

and replace with:

$1_newString_$3

(Other regex processors might use a different capture group syntax, such as \1)
