Hi!

where targer attribute is not present within <a... TAG, and replace
other target attributes - example target="_self" - to _blank. Can
anyone help me? Thanx in advance, and sorry for my english.

yes, then replace the variable of target attribute i have problen with
"finding if target att. is defined and inserting one if not" part. any
idea? thanx in advance.

I hope this is not some homework...

if (preg_match("ta rget", $url)) {
// search and replace
}
else {
// crude but effective, url in form:
// <a href="someplace .html" option="value"> link text</a>
$url_array = explode('>', $url);
$new_url = $url_array[0].' target="your_ta rget">'.$url_ar ray[1] . '>';
}

To do a bit more work, search for the position of the first '>', and
then insert a string into the url (eg. with stripos() and
substr_replace( )) just before that place.

Of if you really want to put effort in, tokenize the whole url, and
then parse the arguments as you see fit.
