Regexp is red,

For my "ie" ie is untrue.

If the number of comma-delimited and tab-delimited elements is always
the same, I would replace all commas with tabs and then filter to have
item x having value of y.

Hi Paul,
AFAIK you need to deal with an hybrid approach (regex + livecode)
So, here is one way to do it:
put 3 into pPage
repeat for each line T in tCiCData
if matchText( T, "(?x) \t (\d+) , \d+ , (\d+) , \d+ \z", n1, n2)
then
if (n1 <= pPage) and (n2 >= pPage) then

Your "ie" is not true. So what do you want?
[a] all lines starting on page 2 OR ending on page 2 OR containing page 2
ie
(pPage >= starting page) OR (pPage <= ending page)
[b] all lines starting on page 2 AND ending on page 2

(pPage >= starting page) AND (pPage <= ending page)

Not sure regex can do what you want, or if it can its far far over my
head. Would it work instead to use lc script to parse?
If you repeat through your data (each line form, with tLine as the current
line and pPage as the page to be looked for...) you can use a one liner
like this to build a list
I have a tab and cr delimited table of data, a sample line of which is
below:
1Test4052,125941,4052,3,2388

So the starting page number is 1 and ending page is 3
I have a variable pPage which contain a page number, say "2"

Hi Skip,
Not sure what can come before /after the string but here's a start
.*/point-.*-landed\.html.*
That will find your string with any number of chars before or after it. If
you need to check for it at the start of a line, replace ".*" with a "^" at
the start of the regexp.

Hi Skip,
If it contains numbers and letters, it could be
/point-item[0-9a-zA-Z]+-landed.html
and if it contains anything except whitespace, it could be

Both options work with the sample data you provided.

/point-item300-landed.html
The results I want returned are:

Hi,
It could be something like this:

put "*/point-*-landed.html" into myFilter
put fld 1 into myData
filter myData without myFilter

Klaus,
Since you have control, then instead of RegEx, you can go like
nodecontent
All in different lines, then, you can just use lineOffset to find the start
node and the end node and copy or replace the data between those lines. It
is easier than RegEx.
