Checking for Weather Alerts

[mercury52]

I have separate parsing for a weather alert. All works fine if I just display the alert (it's either there or not there, displays something or nothing) but I'd like to check to see if it's there so I can do something else (like displaying a text WEATHER ALERT). Can't seem to figure out how to do that.

Can anybody give me some ideas, examples?

Use the code block below to do what you want to do replacing anything with asterisks with you're own data.

Code: Select all

[WeatherAlertCheck]
Measure=Plugin
Plugin=WebParser.dll
URL=*NAME OF THE PARENT WEBPARSE*
StringIndex=*STRING INDEX OF THE CAPTURED WEATHER ALERT*
RegExpSubstitute=1
Substitute="\s":"0";"\S":"1"

[WeatherAlertExists]
Measure=Calc
Formula=[WeatherAlertCheck]
IfEqualValue=0
IfEqualAction=*WHAT TO DO IF WEATHER ALERT DOES NOT EXIST*
IfAboveValue=0
IfAboveAction=*WHAT TO DO IF WEATHER ALERT DOES EXIST*

What I did is:
1. Grab your parsed weather alert data.
2. * Substitute all non white space to 1s and all whitespace to 0s.
3. Send the new substituted string to a calc to convert from a string datatype to a number datatype.
4. Use the IfActions to specify actions.

* You must substitute all non white space characters to even get a match. You must substitute all white space characters otherwise the calc will still read a 0 because it doesn't understand anything other than numbers. Reason why I specify a 0 is because this also ensures no false positives if the webparse picks up whitespace from the data.

Thanks for helping. Bear with me. Since you can only test it out when there is an actual alert I tried the following:
1. I (think) I did what you said and to test it out I changed the substitute values s=1 and S=0 assuming it would then display opposite of what I wanted; didn't do that.
2. I also displayed the string assuming it would contain 1s or 0s; nothing displayed.

When there is something in the string it contains six numbers.
I have included my code to see if you can spot something I did wrong. Didn't know how to add it like you did so I just copied it into this post.

[MeasureAlert]
Measure=Plugin
Plugin=WebParser.dll
URL=http://xml.weather.com/weather/local/USMD0443?cc=*&unit=f&dayf=2
RegExp="(?siU).*<locale>(.*)</locale>.*<ut>(.*)</ut>.*<ud>(.*)</ud>.*<us>(.*)</us>.*<up>(.*)</up>.*<ur>(.*)</ur>.*<loc id="(.*)">.*<dnam>(.*)</dnam>.*<tm>(.*)</tm>.*<lat>(.*)</lat>.*<lon>(.*)</lon>.*<sunr>(.*)</sunr>.*<suns>(.*)</suns>.*<zone>(.*)</zone>.*<a id="(.*)" uc="(.*)">.*<t>(.*)</t>.*<l>(.*)</l>.*"

;15 = number 6dig
;16 = number 1dig
;17 = alert words
;18 = alert web address

[MeasureAdvisoryNr]
Measure=plugin
Plugin=WebParser.dll
URL=[MeasureAlert]
StringIndex=15
RegExpSubstitute=1
Substitute="\s":"0";"\S":"1"

[CheckAdvisory]
Measure=Calc
Formula=[MeasureAdvisoryNr]
ifabovevalue=0
ifaboveaction=!execute [!RainmeterSHOWMeter MeterAdvisory1][!RainmeterSHOWMeter MeterAdvisory2][!RainmeterRedraw]
ifequalvalue=0
ifequalaction=!execute [!RainmeterHIDEMeter MeterAdvisory1][!RainmeterHIDEMeter MeterAdvisory2][!RainmeterRedraw]

Just one quick hint, there is bound to be a weather alert somewhere at any given time. Just look at some national weather news site and find out where it is raining frogs and use that location for testing...

So obvious an idea that I never thought of it.

Well I found Seal Rock OR with a sever weather alert and the alert code is 658255 but my skin with the changes made from santa_ryan did not work. Arrrgh.

I would do something like this:

Code: Select all

[Rainmeter]
Update=1000
DynamicWindowSize=1

[BG]
Meter=Image
SolidColor=0,0,0,255
X=0
Y=0
W=500
H=200

However, in the future please don't hijack threads that have nothing to do with your question. Just start a new thread.

[kabott]

Ho..ok, i thought it was related because of the space character problem, anyways thanks for the help & sorry for the "Hijack" , next time ill start a new thread
