Help on regular expressions

[haibusa2005]

Hi, everyone! I am trying to make a clock skin with a button that changes its appearance depending on the sunrise and sunset times, which means it's one image before sunrise and another after sunrise. I am parsing this page with a regular expression in order to get the sunrise and sunset times. This is the regular expression I am using

Code: Select all

RegExp="(?siU).*<sunr>(.*)</sunr>.*<suns>(.*)</suns>.*"

The return strings are in format "hh:mm AM/PM" which is great for just displaying, but I need a to separate the hours, the minutes and the AM/PM string so I can compare them to local time. I am really bad at regular expressions and have no idea how to parse the time components one by one.

The RegExp (?siU).*<sunr>(.*):(.*)\s.*</sunr>.*<suns>(.*):(.*)\s. will yield:

String Index 01=> 5
String Index 02=> 44
String Index 03=> 8
String Index 04=> 47

So sunrise is 5:44 and sunset is 8:47. I don't suppose you need the AM and PM bits.

I suggest you hurry on over to this post to grab a copy of JSMorley's Rainmeter Regular Expression tester and team it up with this reference sheet to take the pain out of getting RegExps to work properly.

Thanks to JS for the recent update to stop RainRegExp being so "greedy".

Thank you, works like a charm The program of JSMorley is perfect for mastering the regular expressions
