pulling select data from a webpage

3 posts in this topic

Third day writing script so, I'm still mostly stumbling around but I'm happy. I haven't done any programing since I was a kid but I'm getting reminded of how much fun it is. I guess I'm a dork but I like using logic.

Anyway, I've been trying to pull as much info from searching past posts and reading help files but I'm stuck.

I'm trying to get the program to look at select information from a page and act on that either by clicking on a link or by moving on to the next item on the page. Specifically, I'm looking at a typical page on Amazon. I want the program get one of the books on the page (starting with the first) and get the price for that book. (The specific page and books that will be returned will change depending on search so any of the "get by name" functions won't work.)

If someone can point me in the direction of a help file, sample script or whatever, I'd greatly appreciate.

Thanks.

Well first I must say that for your first week of scripting you are attempting a very complex task. You'll probaly need to study this at length before you grasp all of the techniques used. It was an interesting exercise however, so I will show you how it can be done. To figure this out I used the IE Developer Toolbar (recently upgraded by the way and much easier to use) - see my sig. The solution requires knowledge of AutoIt, IE.au3 and the DOM/HTML.

#include <IE.au3>
$sURL = "http://www.amazon.com/s/ref=nb_ss_b/102-5993488-0177751?url=search-alias%3Dstripbooks&field-keywords=mystery&Go.x=0&Go.y=0&Go=Go"
$tryAttach = True
$oIE = _IECreate($sURL, $tryAttach)

$oTables = _IETableGetCollection($oIE)
For $oTable in $oTables
    If String($oTable.className) = "searchresults" Then
        $oTDs = _IETagnameGetCollection($oTable, "td")
        For $oTD in $oTDs
            If String($oTD.className) = "searchitem" Then
                $oSpans = _IETagNameGetCollection($oTD, "span")
                For $oSpan in $oSpans
                    Switch String($oSpan.className)
                        Case "srTitle"
                            ConsoleWrite("Title:      " & _IEPropertyGet($oSpan, "innertext") & @CR)
                        Case "listprice"
                            ConsoleWrite("ListPrice:  " & _IEPropertyGet($oSpan, "innertext") & @CR)
                        Case "saleprice"
                            ConsoleWrite("SalePrice:  " & _IEPropertyGet($oSpan, "innertext") & @CR)
                        Case "sr_price"
                            ConsoleWrite("SRPrice:    " & _IEPropertyGet($oSpan, "innertext") & @CR)
                        Case "otherprice"
                            ConsoleWrite("OtherPrice: " & _IEPropertyGet($oSpan, "innertext") & @CR)
                    EndSwitch
                Next
                ConsoleWrite("--------------------------------------------" & @CR)
            EndIf
        Next
    EndIf   
Next

SciTe Debug mode - it's magic: #AutoIt3Wrapper_run_debug_mode=Y Doesn't work needs to be ripped out of the troubleshooting lexicon. It means that what you tried did not produce the results you expected. It begs the questions 1) what did you try?, 2) what did you expect? and 3) what happened instead?

Thanks so much for this. I honestly am almost completely confused about the code but this is a great starting point for me to start checking things out in the help file and I'll go from there.

Again, I really appreciate your generous help. Thanks!
