Hi,
This is a bit off-topic for this list, I know, but since I know there are a lot of highly competent people on this I'll give it a try...
I'm currently trying to figure out how to use regexp + javascript to parse the content of a web page. What I want to do is collect weather data from a Norwegian website and include it in a dashboard widget.
Here is the site with an example search: http://tux.aftenposten.no/weathersearch/weathersearch.do? name=levanger&sok=limnor
I tried to copy the source into TextMate and use the regexp search in TM to figure out the patterns to use, but I can't seem to solve it. Any help are appreciated.
As far as I can see, the weather data for a particular day are enclosed by <tr><td class="idag" ... </tr>, but there is a lot of space around the tags, which I presume must be included in the regexp patterns.
Anyone here which could kick me in the right direction when it comes to these patterns? -- Mvh/Regards Geir-Tore Lindsve lindsve@bluezone.no http://www.lindsve.net

Although it's early morning here, would I suggest :
Find: <tr>[\s\n]+<td\s+class="idag(((.|\n)(?!</tr>))+).</tr>

Thanks! That seems to be right on the spot when it comes to one particular day, and I guess I can twist my brain enough to figure out how to find the individual data inside those blocks.
\s is space?
What does the pattern actually say between "idag" and </tr>? -- Mvh/Regards Geir-Tore Lindsve lindsve@bluezone.no http://www.lindsve.net

in one word "RTFM" (Help->TextMate Help->19 Regular Expressions)
\s is space?
whitespace char (space, tab...)
What does the pattern actually say between "idag" and </tr>?
« one or more character or end of line not followed by "</tr>", one character and </tr> »
Btw, i could have done it shorter : Find: <tr>[\s\n]+<td\s+class="idag(((.|\n)(?!/tr>))+)</tr>
Can't Dashboard widgets access the DOM of loaded web pages ? If so, document.getElementById('idag').innerHTML is probably easier/faster.
