Re: Regex help...
@Paul,
to defend you, it's not always so obvious to know what we can or cannot do
with regex.
@Mike
yes, Perl is great and that's certainly why I have embeded Perl in
LiveCode, Mmm, more than 10 years ago.
I've also helped some well known LiveCoders to do some complex
transformation with Perl where
they were lost in pure LiveCode script; but this is another story.
By the way, there is a not free LiveCode library called sunnYrex which
accepts LiveCode script inside
the replacement text.. pretty cool too but not useful in Paul use case.
Kind regards,
Thierry

Re: Regex help...
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
put T & cr after tCiCfilteredData
end if
end if
end repeat
put tCiCfilteredData
But for the curious with an open-mind here is another solution:
get "perl -ne 'print if /\t(\d+),\d+,(\d+),\d+$(?(?{$1>PP ||
$2PP || $2PP || $2:

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?

Thierry Douez write: Regex has been around a long time and lots of smart computer science types has spent time coming up with ways to optimize its performance for pattern matching. That's was true, it's still true and will always be true!

Hi Mark, There's huge differences in how regex implementations perform in different languages. For example: http://raid6.com.au/~onlyjob/posts/arena/ Perl outperforms everything in that test. I've never assumed that LC's "perl compatiable regex library" is going to perform at the speed which actual Perl performs. I've always assumed that being "perl compatible" just meant that all syntactically-correct Perl regexs should run with LC's implementation, without needing any kind of change in how the regex is formatted. There was an academic paper I came across 15 years ago, which showed that Tcl out-performed Perl. Now it seems Perl outperforms Tcl, suggesting that one or the other has made changes to their underlying engine which impact regex performance. Or that the tests I read about 15 years ago were just testing regex features which resulted in Tcl out-performing Perl, and vice-versa in the above test. It would be great if LC's implementation was as fast as Perl's. Here's a page comparing several implementations of PCRE (with some non-pcre regex implementations): http://sljit.sourceforge.net/regex_perf.html One of the things we had in LC5 which was phenomenally fast, was searching through the styledText of a field. That fast way of searching particular text structures got lost in the migration to LC8.

One of the reasons for my seemingly-obsessive benchmarking is to learn about what goes on under the hood, and to try to anticipate it when choosing among different algos. LC does such a good job of shielding us from what goes on under the hood that we often forget that the relationship between the number of lines we write and the number of machine instructions our scripts invoke may differ broadly depending on the statement. My favorite example is: set the scroll of field 1 to 100 -- seems simple enough, but having written scrollbar management routines in C back in the pre-Cocoa days I learned that a *tremendous* number of low-level routines come into play with that one simple line of script. LC makes it easy to take this stuff for granted, since it does all the heavy lifting. Same with regex. The beauty of regex is that it's a very generalized solution. The downside of regex is that it's a very generalized solution. ;) Generalized options can provide convenience, but often at the cost of performance. Purpose-built solutions are usually much faster than generalized ones, and with LC's chunk expressions they're fun to write too. :) There are times when regex will outperform chunk expressions, though, so I would caution against rewriting everything. Benchmarking is the key, and some day I will have done enough to be able to come up with a small set of useful rules as to when to use chunks and when to use regex. But at the moment, it's half hunch and half benchmarking to confirm the hunch. -- Richard Gaskin Fourth World Systems Software Design and Development for the Desktop, Mobile, and the Web ambassa...@fourthworld.comhttp://www.FourthWorld.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Re: AW: Re: Regex help needed...
Wow. I would not have expected such a significant difference. Regex has been around a long time and lots of smart computer science types has spent time coming up with ways to optimize its performance for pattern matching. I assumed (falsely) that regex based filters in LC would be on par or even superior than a custom function using chunks. This leads me to: 1) wondering if LC's hooks to whatever regex tool they are using under the hood is a good as it should be AND 2) planning on rewriting my code to use chunks. Thanks for the post.

Re: AW: Re: Regex help needed...
Regex is wonderfully compact to write relative to equivalent routines using chunk expressions, but sometimes paid for in execution time. When I come across a good regex example like the one you provided, if I have a moment I like to test things out to see where regex is faster and where it isn't. It's really great for many things, but carries quite a bit of overhead. Of course for this test to be relevant it assumes that most of the specifiers in the regex expression are merely to identify the elements you're looking for, and that the data is expected to fit the definition you provided. Given that, it's possible to make the regex a bit simpler (see foo2 below), but only with a modest boost to performance. It can probably be simplified more, but the chunk-based alternative performed so well I didn't bother exploring the regex side any further. Writing a lengthier handler that uses chunk expressions seems to yield the same results you reported, running between 12 and 60 times faster (depending on the percentage of lines tested that match the criteria being looked for). For one-offs like validating email addresses regex can be an excellent fit, and even some larger tasks depending on the specifics. But for iterating across lists I've often been delightfully surprised by LiveCode's gracefully efficient chunk handling. Testing your original data replicated to become 250 lines long, and looking for page 1 among them, the script below yields: Regex: 9261 ms RegexLite: 7958 ms Chunks: 197 ms Chunks faster than orig regex by: 47.01 times Chunks faster than lite regex by: 40.4 times Same result? true on mouseUp put fld 1 into tList put 1 into tPage --< change this for different tests put 1000 into n -- -- Test 1: original regex put the millisecs into t repeat n put foo1(tPage, tList) into r1 end repeat put the millisecs - t into t1 -- -- Test 2: lighter regex put the millisecs into t repeat n put foo2(tPage, tList) into r2 end repeat put the millisecs - t into t2 -- -- Test 3: chunks put the millisecs into t repeat n put foo3(tPage, tList) into r3 end repeat put the millisecs - t into t3 -- -- Display results: set the numberformat to "0.##" put "Regex: "&t1 &" ms"&cr \ &"RegexLite: "&t2 &" ms"&cr \ &"Chunks: "& t3 &" ms"&cr \ &"Chunks faster than orig regex by: "&(t1 / t3)&" times" &cr \ &"Chunks faster than lite regex by: "&(t2 / t3)&" times" &cr \ &"Same result?

Re: Regex Help
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.

Thanks Mark, Actually look for the regex version as I will be applying that externally before feeding into LC.

Mark Weider's code will work for you, Klaus… the "tValue" is something that the matchText function FILLS with the current text inside the brackets, so you don't need to know it ahead of time. The "(.*?)" is a way to "capture" what is between the tags, and the 3rd+ parameters to he matchTextFunction are variables that are provided to the function that get filled with whatever is being captured. The matchText function returns either 'true' (if it can find what you are looking for) or 'false') if it can't. Mark's code above assumes a 'true' result by using "get". Here's an example that takes into account the possibility that you may not match what you're looking for: put "Hello" into tData if matchText(tData,"(?s)(.*?)",tValue) = "true" then put tValue -- Since this matches, you'll get "Hello" in the msg box else put "No Match" end if > Ken Ray Sons of Thunder Software, Inc.

You might take a look at the code again. In both cases you hand in the whole XML text, the tag you want to replace, and the value you want to stuff into it. The matchText function gets the current value in that tag.

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.

Nonetheless, if you want to continue down the regex path, try something like get matchText(tText,"(?s)<" & tTag & ">(.*?)",tValue) replace "<" & tTag & ">" & tValue " with "<" & tTag & ">" & tNewValue " in tText -- Mark Wieder ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Re: regex help please
Klaus, I used to work like that, doing little XML files with RegEx and matchText. After working like that for a long time, I came to realize that there was no advantage at all in my case. It was simpler to work with RevXML. The problem with RegEx is all the little cases where it fails. I think you should use RevXML, it might look overkill but it will cut your debug time a lot.
