Hello Regular Expression Geeks.
I need a hand... Could anyone help me to build a regular expression for finding
IMG tags in html files that do NOT have a "BORDER=" parameter?
for example:
<img src="foo.jpg"> matches
<img border="" src="foo.jpg"> no match
<img src="foo.jpg" border="0"> no match
<img src="foo.jpg" border="0" height="75"> no match
<img src="foo.jpg" width="50"> matches
I previously wrote the following to find IMG tags that had a border other than
"1":
<img[^>]*border="[02-9 ]?"[^>]*>
Which worked fine, accepting that parameters are all delimited by double quotes
in the files that I am working with.
I'm not sure if Regular Expressions can be used in this fashion, but then I'm
pretty new to them.
Any assistance would be appreciated, thanks.

For *BORDER* tags, you're in luck: /<img(\s+[^bB]\w+=("...|\S*))*>/i But that is on the (valid?) presumption that the ONLY attribute for an <img> tag that starts with the letter "B" is "BORDER". I suppose I could be wrong what with all the (...) (21 years ago, 8-Jul-03, to lugnet.off-topic.geek)
