IE Help

[KenNichols]

I am new to working with web pages with AutoIt and still kinda new to working with AutoIt in general. What I am trying to do is extract how many miles it is from point A to point B.

$start = InputBox("Starting Address","Enter your starting address:")

$end = InputBox("Ending Address","Enter your ending address:")

$url = "http://maps.google.com/maps?f=d&hl=en&saddr="&StringReplace($start," ","+")&"&daddr="&StringReplace($end," ","+")

RunWait("rundll32.exe url.dll,FileProtocolHandler " & $url, @WorkingDir)

After the web page is displayed I need to extract how many miles it is between the start and end address.

It's right there on the page but I do not know how to pull the information out.

That will open the user's default browser, which may NOT be IE.

Examine the page with a DOM inspector like DebugBar to see where the text you want is, then get it using the _IE* functions of the IE.au3 UDF. If it's not buried inside frames, you might get it with just _IEBodyReadText() and a StringRegExp().

I believe there's a simpler way:

Just after posting, I realized there was a visual "side effect" here! Look, between the 2 regex captures, there was an "ampersand#160;" code (an html hard whitespace) which was immediately transformed into a real hard whitespace by posting the code in ... an html page! Now there's the .* (limited by non greediness) instead.

CODE

#include <inet.au3>

$start = InputBox("Starting Address","Enter your starting address:")

$end = InputBox("Ending Address","Enter your ending address:")

$url = "http://maps.google.com/maps?f=d&hl=en&output=html&saddr="&StringReplace($start," ","+")&"&daddr="&StringReplace($end," ","+")

;; note the new parameter here --------------^^^^^^^^^^^^

$html = _InetGetsource($url) ;; gets the source without having to bother with any window

If @error Then

MsgBox(0, "", "An error occured while capturing Web page source!")

Exit

EndIf

;; Capture distance and unit

$data = StringRegExp($html, "(?U)dditd><div><b>([0-9.]*).*([a-z]*)", 1)

If @error <> 0 Then

MsgBox(0, "", "An error occured while extracting data" & @LF _

& "Page format did change. Check new source html code.")

Exit

EndIf

ConsoleWrite($data[0])

;; handle $data[*] gracefully here

MsgBox(0, "Result", "Distance is " & $data[0] & " " & $data[1])

You'll have to barricade against all sorts of errors (e.g. incomplete or ambiguous user input), but it can be done. Edited April 18, 2009 by jchd

Let me start out by thanking all 3 of you! I did download DebugBar and I understand this a whole lot better!

I am having trouble understanding StringRegExp now.

If $Result = ###.# then it works fine but if it = #,### then it comes up #,# and not #,###.

I hope this makes sense to someone!

$data = StringRegExp($Result, "([0-9]*.[0-9])",1)

I am having trouble understanding StringRegExp now.

That is for another thread, please start a new thread for StringRegExp

Wanting to be able to grab (driving) mileage values from Google as well, and grateful for this and a similar thread.

Given that the above code no longer seems to work, I'm wondering if Google perhaps changed their data structure...are we looking for something other than "dditd"?

Was this prior to Google incorporating various suggested routes?

Any clues?

Thanks,

Ed

Ahhh, this was simple. It is the html id="altroute_0" that we are looking for, so simply changing dditd to altroute_0 in the above code does the trick. Can get altroute_1 or altroute_2 as well if those are presented.
