IE + regex + split() != fun
I'm putting together something for a property selling web site to list the particulars of each property. I've loaded all the properties from the DB (*cough* large text file) into a huge 2D array and one column is a freeform(ish) field called "Remarks" that will contain the blurb.
I've managed to convince the people that write the details to stick to a fairly rigid format to make it easier to parse out to the screen. So the general format of the field is:
HEADING: description. HEADING: description leading to... HEADING: description. and so on
where HEADING is all in capitals, immediately followed by a colon, and may contain spaces, hyphens, slashes or numbers. The 'description' can be pretty much any characters, or may be empty if there's a double heading such as FIRST FLOOR: BEDROOM 1:
So I want to split this mammoth text field into its component "HEADING" and "description" parts such that I can iterate over them and apply formatting by shoving each bit into divs or table cells to separate them.
The issue is slightly murkier because the HEADING is normally a room of the house and thus could be simple like "BEDROOM 3" or could be "W.C." or perhaps "SPARE/UTILITY ROOM". They also sometimes start a paragraph in the description field with "N.B:", which is infuriating but I guess I'll just have to treat it as a HEADING.
The problem is JScript/IE (6, not sure about 7) and its handling of split and regexes. Firefox works a charm with this [horrible] expression:
regex = /(W\.C|N\.B|[A-Z1-9\s*\/-]+:)+(.*?)/g; remarkItems = properties[currPropIdx].remarks.split(regex);
Can anyone with a bigger brain then me perhaps suggest a way of making this work more cross-browser, or point me in a new direction; perhaps using some other means of splitting this string up? It's probably monumentally easy and I'm just being stupid, but staring at the code, making adjustments and proclaiming "why!?" a lot hasn't got me very far
Thanks in advance for any pointers.
btw, here's some sample output of the field in question:
