Thanks for the post Paul. I did try <tr[^>]*>.*</tr> but the middle bit
matches anything - including </tr> so I get the whole of the rest of the
page.
I don't actually want any of the row returned - I just want to make sure
that this row is in the correct format (i.e. has 3 cells with meeting,
date and venue in) so that I can start looping through the remaining
rows in the table to get what I want.
Can anyone else help with this? I have attached the page I am working
with (if this list allows attachments) what I want to do is get the
address of each meeting index file (in this case there is only 1 at
mtg11/index.htm, the file name of the registered drivers page and the
file name of the series file (in this case ser1/series.htm).
Thanks

I'm quite confused by this! It's not entirely clear what you want to
do, so let's try and figure this out!
I am assuming that by a row, you mean the bits between a <tr> and a
</tr>.
So, you are trying to find:
1) <tr> although it may have attributes so it would be <tr[^>]*>
2) anything that isn't a </tr>
3) </tr>
the first and last bits are easy so the regex can begin to take shape:
<tr[^>]*>[[2]]</tr>
It's just the [[2]] bit that we're now interested in! And it's a lot
simpler than you may think. Remember that a regex is going to search
for the WHOLE string, not just look for the next bit of itself. And the
regex knows that the string ends in </tr> so it will look for something
starting with a <tr> tag and ending with a </tr> tag won't it! In other
words this should work (untested):
<tr[^>]*>.*</tr>
But, the point is, do you need the [[2]] bit? With a regular expression
you are finding the start of the string, and not the actual string
itself. To return the string, you need to find:
1) the end of the <tr> tag + 1
2) the start of the closing </tr> tag - do a find on </tr> using a start
position of (1)
3) Do a Mid on the string with those values
So instead of a regex, it becomes (htmlstr is the string you are working
on):
<cfscript>
// find end of opening <tr>
start = Find(">", htmlstr, find("<tr", htmlstr)) + 1;
// find ending </tr>
end = find("</tr>", htmlstr, start);
trstring = mid(htmlstr, start, end - start);
</cfscript>
and out pops trstring! This could easily just be a one liner too! No
need for a regex anywhere (although you can use the above instead of the
start equation)! Remember though this will return what is INSIDE the
tag, and not the actual tag itself. To do that, find the start of the
<tr and the end of the </tr> and it will pop out!
Paul
