You have two problems.

1) You need to add DynamicWindowSize=1 to the [Rainmeter] section of your skin, so the meter grows to fit the retrieved data properly.

2) Your RegExp is going to return the correct value, except that it will also return the linefeeds and spaces on either side of the value. You need to alter it to RegExp="(?siU).*<div style="width:345px;float:left; margin-top:11px; overflow:hidden">.*(\w.*)\W</div>". What this will do is: after hidden"> it will skip everything .* until a "word" char \w that is a-Z|0-9 is hit. Then it will capture everything until a non "word" char \W is hit (the linefeed at the end of the value).

That way you end up with:

Code: Select all

01=> Unknown Artist - Unknown Title

Instead of:

Code: Select all

01=> 
                            Unknown Artist - Unknown Title

I was playing around with your RegExp, but jsmorley already covered all problems. I went for another RegExp, though, because in my trials the provided RegExp was parsing things it shouldn't;
Here it is:

Code: Select all

(?siU).*<a href="/release/.*" style="color: #FFFFFF">(.*)</a>

P.S. For any other beginner user that may come to this page trying to figure out how to parse lines in Webparser, I will link this awesome post here.

I have a similar problem and have tried this suggestion but still no go. Any Ideas ?

[Price3]
MeasureName=LoadBuff
Meter=STRING

StringIndex=1
DynamicVariables=1
text=Buff :%1

debug log is

So it finds the right data 3.809 which is between a <h2> and an </h2)
but the text=Buff :%1
displays nothing

strange
I have another skin similar that works ok.

Fixed it
cut out the 2 measures

Code: Select all

[pr2]
Measure=Plugin
Plugin=Plugins\WebParser.dll
Url=[Loadfile]
StringIndex=1
Debug=1

[pr3]
Measure=Plugin
Plugin=Plugins\WebParser.dll
Url=[Loadbuff]
StringIndex=1
Debug=1

added
StringIndex=1
to

Code: Select all

[Loadfile]
Measure=Plugin
Plugin=Plugins\WebParser.dll
UpdateRate=1200
Url=#UrL1#
RegExp=#RegExp1#
StringIndex=1
Debug=1

and it works now
not sure why it didn't work with
previous code
