need a little help building an array

13 posts in this topic

Guys,

      For the life of me, I can figure out how to do this simple task. I want to populate an array with a list of links. I can populate the array with one link at the time but for the main part of my script I need the full list of links so I can use a Ubound to count through them.

Local $oIE = _IECreate("http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/")
Local $links =  _IELinkGetCollection($oIE)

    For $link In $links
        
        If StringInStr($link.href,"http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/?Model=") Then
            ConsoleWrite("Link Found: " & $Link.href & @CRLF)

            $linkarray = StringSplit($link.href,' ',2)

        EndIf
    Next
_ArrayDisplay($linkarray)

What am I missing here guys???

Look at the function _StringBetween()

Something like.

Local $oIE = _IECreate("http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/")
Local $code = _IEBodyReadHTML($oIE)

$aLinks = _StringBetween($code, 'http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/?Model=', '"')

_ArrayDisplay($aLinks)

Thanks John! That is one way to do it that I didn't think of. Can you show me how to build the array with the string data. I will use your example in my main script this time but I really want to learn how to build the array. I have other scripts that this would be useful on. I tried using the _ArrayAdd function but I could not get it to work. I was thinking that I could use some thing like this

Local $oIE = _IECreate("http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/")
Local $links =  _IELinkGetCollection($oIE)
Global $myarray
    For $link In $links
        
        If StringInStr($link.href,"http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/?Model=") Then
            ConsoleWrite("Link Found: " & $Link.href & @CRLF)

            Local $linkarray = StringSplit($link.href,' ')

        EndIf

        _Arrayadd ($myarray,$linkarray)
    Next
_ArrayDisplay($myarray)

and I could not get that to work. Also, I tried using this _ArrayAdd($myarray, $link.href) but that didn't work either.

Probably something like....

#include <IE.au3>
#include <Array.au3>

Local $oIE = _IECreate("http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/")
Local $links = _IELinkGetCollection($oIE)
Global $myarray
For $link In $links

    If StringInStr($link.href, "http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/?Model=") Then
        ConsoleWrite("Link Found: " & $Link.href & @CRLF)
        _ArrayAdd($myarray, $link.href)
    EndIf

Next
_ArrayDisplay($myarray)

That's exactly what I thought but I keep getting an error. If I understand the help file correctly, I should be able to use _ArrayAdd($myarray,"my value here") and it should insert it at the end of $myarray. Question??? Am I declaring the array incorrectly?

Not sure, try...

#include <IE.au3>
#include <Array.au3>

Local $oIE = _IECreate("http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/")
Local $links = _IELinkGetCollection($oIE)
Global $myarray[1] = 1
For $link In $links

    If StringInStr($link.href, "http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/?Model=") Then
        ConsoleWrite("Link Found: " & $Link.href & @CRLF)
        _ArrayAdd($myarray, $link.href)
        $myarray[UBound($myarray)-1] += 1
    EndIf

Next
_ArrayDisplay($myarray)

Syntax error.

Local  $myarray[1] = 1
~~~~~~~~~~~~~~~~~^

Let me try something real quick. I don't think the array is being declared. I'm gonna throw some text in there just to see what it does.

that's it. I just made the variable into an array. $myarray[1] = ["text"] and it worked perfectly. Is this the only way to declare an array before you actually use it???

RickB75,

Try this.  See comments in code...

#include <ie.au3>
#include <array.au3>

local $aLinks[1]                                        ; declare your array with one entry

Local $oIE = _IECreate("http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/",0,0)
Local $links =  _IELinkGetCollection($oIE)

    For $link In $links

        If StringInStr($link.href,"http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/?Model=") Then
            ConsoleWrite("Link Found: " & $Link.href & @CRLF)

            $aLinks[ubound($aLinks)-1] = $link.href     ; add the link to your array
            redim $aLinks[ubound($aLinks)+1]            ; increase array by one

        EndIf
    Next
_ArrayDisplay($aLinks)

Yeah sorry about that, my mistake.

Depends what function is using it I suppose.

I'd keep $myarray[1] = [0], that way $myarray[0] should should always hold the count of links found.

I like it like this, so your array is always perfectly defined (no empty bounds)...but that's just personal pref...another way, would be to delete the UBound dim, after you exit the for loop (kylomas sample)

#include <ie.au3>
#include <array.au3>

local $aLinks                                       ; declare the variable to become the array

Local $oIE = _IECreate("http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/",0,0)
Local $links =  _IELinkGetCollection($oIE)

    For $link In $links

        If StringInStr($link.href,"http://graydanielsnissanofjackson.com/Jackson-MS/For-Sale/New/?Model=") Then
            ConsoleWrite("Link Found: " & $Link.href & @CRLF)
            
            If IsArray($aLinks) Then
                ReDim $aLinks[ubound($aLinks)+1]
            Else
                Local $aLinks[1]
            EndIf
            $aLinks[ubound($aLinks)-1] = $link.href     ; add the link to your array
        EndIf
    Next
_ArrayDisplay($aLinks)

With most of the scripts I've written, I've really never had to build an array from scratch. I've always had the data for the most part and it was a matter of declaring, sorting or deleting data in the array or telling the script the specified data in the array I needed. I never really had to build the arrays like this. This will help with my other scripts because I write a ton of data into Excel and I'm currently doing it line by line. It will be sooooo much faster to actually insert the array into an Excel worksheet. Thank you guys sooooo much for your help.
