Yes, it will match that whitespace unless the /x modifier is set.

Yes, so it's greedy. It will match as much as possible untill the second=
=
match.
consider:
'<a>foo</a>bar<a>baz</a>foz'
'|<a>.+</a>|' will match '<a>foo</a>bar<a>baz</a>'
'|<a>.+?</a>|' will match '<a>foo</a>'

In your case, I'd possibly use:
$regexp =3D "%<table[^>]*>(.+?)<img%si";
(the /i modifier will make the dot match linebreaks, which is possibly t=
he =
breaking point for your regex).
Highly depends on the actual markup wether this will work though...
