Search and Replace Regular Expression

does anyone else find Search and Replace Pattern.vi useless?

It seems to me that you can't remove all the <HTML> tags from a string with it.

I substituted Match Regular Expression for Match Pattern, creating a

new VI called Search and Replace Regular Expression...

any thoughts as to why NI didn't do this already?

wouldn't it also be nice if there was a PCRE node where small Perl-like

scripts could be used?

To me it seems that Search and Replace Pattern.vi IS able to remove the tags, see attched example.

Can you post a specific example where it doesn't work? (Or maybe I misunderstood what you want to achieve?)

Your code does indeed work.

However, I'm reading the Details sections of the Match Pattern help page, and I don't understand

what the regex <[^>]*> means? I can't decipher it from the Match Pattern Details page.

On the other hand, I've used Perl alot in the past, so <.*?> is more natural for me.

The match pattern reads

< match of the '<' character

[^>]* any number of characters other than '>'

> match of the '>' character
