I think you might need replacetext(tData,"<.*?>",empty)

The '?' cause the match to be non-greedy. Without it, everything from the first 
"<" to the last ">" will be replaced.

Thanks Mike, pilot error here - replacetext(tData,"<.*>",empty) looks to be a 
viable direction of travel once correctly typed. Time to rest my eyes, 
methinks! 8-)

Re: Any characters wildcard or regex?

[Mike Bonner]

if you want to use regex, I think you have to use replacetext rather than
replace, unless replace has been updated when I wasn't looking.
I did a quicky test..

put field 1 into tData -- field with text containing html tags
put replacetext(tData,"<.*>",empty) into tNewData
put tNewData

Also, in your example above I assume you correctly set the htmltext rather
than the html..

Re: Any characters wildcard or regex?

[Keith Clarke]

Thanks Mike & Klaus,
The simple line 'replace "<.*>" with empty in tFileText’ would be ideal, but it 
seems to be ignored.

The html approach seems to hit an early hurdle, too - if I...

set the html of field "FldFileText" to URL(tFileName)
set the text of field "FldFileText" to the text of field “FldFileText

...this results in an empty field after the first or both lines. Perhaps this 
is because the source file is a CSV with only one item having any HTML tags?

Just to clarify the problem - the source text I’m working with comes from CSV 
file imports and some files contain RTF fields amongst their items. These RTF 
styling tags sometimes contain quotes & commas that are causing occasional 
glitches with the CSV item delimiting - hence the need to pre-process and strip 
out all tags before processing the CSV import. 

Thanks again for your insights.
Best,
Keith..

you can even (ab)use "the templatefield" for this:
...
set the htmltext of the templatefield to url("http://your_url/here.html;)
put the text of the templatefield into fld 1 # or a variable
reset the templatefield ## !!

Re: Any characters wildcard or regex?

Using replacetext, you're probably looking for "<.*>"
but you might be able to use a field for this..  set the htmltext of the
field to your source text, Then if you don't want the formatting preserved
set the text of the field to the text of the field.  One problem with this
method is that you may end up with javascript left over because it can
appear between  and
