Hi Stefan,

I thought about using a XML-Parser, but I'm not sure if this will work 
for Craftkiller, since he does not want to remove all tags (if I 
understood him right).

No, this won't work. Replace with patterns will only work with 
RegularExpressions. * has a completely different meaning in RegExp and 
is not the placeholder for any characters. In fact, * stands for "No or 
multiple occurrence of the character directly before the *" and is a so 
called "Mask-charcter".

I'm not sure what you want to delete (by the way - forget about what I 
wrote with CLF/LF - this is an RB option, that the replace stops on 
first match by default):
  dim re as new regEx

  re.SearchPattern = "(<link>|</link>|<title>|</title>|<a 
href=.+?>|</a>)|<.+?>"
  re.ReplacementPattern = "$1"
  re.Options.ReplaceAllMatches = true
  EditField1.text = re.replace(EditField1.text)


This regexp will do the following to the content of EditField1 (in my 
example the RSS-feed of RB with an additional link):

All tags in the ( ) seperated each by a pipe (|) will be "ignored" 
(replaced by themself). "re.Options.ReplaceAllMatches = true" makes the 
RegExp walk through all matches.
I hope this is what you need. If not, please send two examples of your 
code you want to be replaced. One "before replacing", the other after 
replacing. I'll then make you a RegExp asap.


Best regards,
Erik
