Hi,
I really struggle with regex, and would appreciate some guidance. Basically, I have a whole load of files (HTML) which are updated every few minutes. I need to go through each line, looking for the word CONFIRMED: (which is always in capitals, and always superseded by a colon). The line looks like this:
22.5 J.Smith at Thropton, CONFIRMED: more text here, including commas and info on the appointment etc
There are other similar appointments that haven't yet been confirmed, so..I just need to pick out the confirmed ones. Once the regex finds "CONFIRMED:" I also need it to grab the text up to and including the date (22.5). I don't really need any text *after* "CONFIRMED:" yet, but possible in the future.
There seem to be a lot of tutorials on, eg, getting hrefs from anchor tags, but I can't get my head around this particular one. Any ideas or pointers would be great
Loop through your file, one at a time and match using the following:
if ( ereg("^(.*)CONFIRMED:", $line, $ary) ) {
$text = $ary[1]; // $text now contains what matched in (.*) above
}This will mostly work. Unless "CONFIRMED:" can appear multiple times per line.
The other way to do this would be via the shell...
grep "CONFIRMED:" *.html | sed 's/CONFIRMED:.*//'
would spit out all the matching lines from all your files..
good luck.
