That's what I was looking for - Thanks for all your help

I try to give folks a way to learn -- give them a fishing pole & guide them...

so what have you tried?


you'd use the http.download() and that would go to a file.
then use TextFile.ReadToString() to read in that file.
Then use String.Find() and String.Mid() to "pull" the information between the markers.

I'll come up with an example using that website in a few days for you.. but it's a low priority for me.. (I hope you understand)

No problem - I appreciate all your time and help!

Thanks again

Hello,

Could use some more help with extracting data from text file. I would like to extract the 5 day forecast and display each day into a paragraph. The problem is I do not understand how to get the data from the text file then write it to a string. When looking at the text file I do not know what to look for or how to get the data into ams to display into a paragraph along with image (rain, clouds etc). If someone could show me a sample for one day and where to get the data from the text file - It would be greatly appreciated.

Sorry still learning - Thanks

Try looking at the section below in your text file for the "OAS_query = " values.

That appears to hold what your looking for.

<!-- MJX config controlled by pif_btrav_tenday_long -->
<SCRIPT LANGUAGE="JavaScript">
<!--
OAS_MJX_on = true; // when true, this allows the MJX ad request to be made
OAS_spoof = '/p/f/r/p/5day/us/nj/504/mays_landing/08330.';
OAS_listpos = 'PageCounter,HeaderSpon,WindowShade,Classified,PageSpon,PageSpon2,PdSearch,PageSpon3,PageSpon4,Hidden1,Hidden2';
OAS_query = 'context=trvl_btrav_tenday&templ1=38&temph2=51&templ2=32&fcond2=cloud_mostly&temph3=51&templ3=33&fcond3=clear_mostly_sunny&';
CM_tag = 'null';
// -->
</SCRIPT>

Just use necessary String commands to parse the data.

Here is the code that gets current image and temp.
I 'm still confused on how to do this. How do I get each day temp and image to read to 5 different paragraphs. I'm a visual person - I need to see some type of smaple to understand. The code posted below just confuses me - I don't understand (yet) how to get the data and pass to a string. Any help would be great. Thanks

-- A function that accepts two values and returns one value
function fetchWeather(URL)
	StatusDlg.Hide();
	HTTP.Download(URL, _TempFolder .. "\\weather.htm", MODE_TEXT, 30, 80)
	StatusDlg.Hide();
end

function displayWeather()
	if (File.DoesExist(_TempFolder .. "\\weather.htm")) then
		html = TextFile.ReadToString(_TempFolder .. "\\weather.htm");
		if (string.find(html, '<strong class="obsTempTextA">(.+)&deg;F</strong><br/>') ~= nil) then
			temperature = string.sub(html, string.find(html, '<strong class="obsTempTextA">(.+)&deg;F</strong><br/>'));
			value = String.Mid(temperature, 30, String.Length(temperature) - 49);
			Label.SetText("weather", value .. "°F");
		else
			Label.SetText("weather", "???");
		end
	end
end

function fetchImage()
	if (File.DoesExist(_TempFolder .. "\\weather.htm")) then
		html = TextFile.ReadToString(_TempFolder .. "\\weather.htm");
		if (string.find(html, '<div class="cImage"><img width="52" height="52" border="0" src="(.+)" alt=""/><br/>') ~= nil) then
			image = string.sub(html, string.find(html, '<div class="cImage"><img width="52" height="52" border="0" src="(.+)" alt=""/><br/>'));
			url = String.Mid(image, 65, String.Length(image) - 80);
			HTTP.Download(url, _TempFolder .. "\\image.png", MODE_BINARY, 30, 80);
			error = Application.GetLastError();
			if (error == 0) then
				Image.Load("Image1", _TempFolder .. "\\image.png");
			end
		end
	end
end

I believe that "a small sample" was already given. Actually, a whole solution how to search for strings in a document is shown in my code.

The code I presented before showed how to fetch specific information from a specific HTML file. If the file structure changes, or if you want to fetch different informations, the functions won't work without modifications. And to be able to do that, you have to understand what they do. You won't learn just copying somebody's work - try to see what is done, and why. Use the debug window to inspect what the variables contain as the function is processed.

I am showing you now a new project, which demonstrates how to retrieve 5 days of weather forecast. If this page on the Weather.com web site changes its structure, you will have to adjust the code accordingly, or the information won't be found and something might end up missing on the screen.

upeters - Thanks again for your help.

I tried to see what and how it was done. Still does not make sense too me.
I still do not understand how you pull the data from the text file.

With time I will learn - Thanks

Hello,

I was wonder if it is possible have an input object so, you can type a ZIP code and it would go fetech the data with images. If so, how can it be done?

I have tried for a few weeks working with parsing data - I don't think I will ever understand how to do it.

Thanks!
