Get HTML Table Cell

8 posts in this topic

Hello there,

I'd like to get some data from this site, but I don't have the slightest idea how to get the data from a specific table cell.

What I'm trying to automate is load the site, then search using the postcode from an excel file, then get back the data found on the site to the excel file.

The site is: [link]http://www.petrolprices.com/search.html?search=heathrow[/link]

The problem is I don't know how to get the "Lowest price in this area:" fields.

Do you have any idea where I can find an answer?

Thanks in advance!

Thank you, it seems that I can take out the data in to an array as it is a table. Unfortunately, I'll have to study working with arrays...I haven't done that before so it will be a long run.

Thanks again!

It's a good time to learn.

I'm really trying to find out how to get a specific cell from an array, but just can't figure it out.

Can you give me an example?

If you know the index number then it would look something like $array[$index_number].

If you only know what type of value you want, then you need to study on Loops + String functions to enumerate through the array and search its values.

Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.

I've checked the faq, thanks for the link, it's very useful.

However, I couldn't find out how to get the string I need.

My code looks like this:

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

Global $aTableData[25]
$excelss="template.xls"
$excel=_ExcelAttach($excelss,"FileName")
$oIE = _IECreate ("http://www.petrolprices.com/")
_IELoadWait ($oIE)
WinSetState("","",@SW_MAXIMIZE)

$searchfld=_IEGetObjByName($oIE,"search")
_IEFormElementSetValue ($searchfld, "heathrow")
$searchfld.Select
send("{enter}")
_IELoadWait ($oIE)
;$price=_IEGetObjById($oIE,4)

$oTable = _IETableGetCollection ($oIE, 0)
$aTableData = _IETableWriteToArray ($oTable)
;_ArrayDisplay($aTableData)
;$lofasz=_ArrayToString($aTableData,"")
$mystring=$aTableData[1]
$excel.cells(4,2).select
$excel.cells(4,2)=$mystring

Of course this is not woring this way. Could you point me to the right direction?

Is there any other way to get the table as this array thing looks far too complicated to me...

At last I could figure out how to do this. Here's the working code:

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

Dim $searchfld
Dim $aTableData[10][20]
$excelss="weekly_blank_form.xls"
$excel=_ExcelAttach($excelss,"FileName")
$oIE = _IECreate ("http://www.petrolprices.com/")
_IELoadWait ($oIE)
WinSetState("","",@SW_MAXIMIZE)

$rowx=InputBox("Last Row","Enter last row number")
$row=5
Do
    $searchW=$excel.cells($row,5)
    $searchfld=_IEGetObjByName($oIE,"search")
    _IEFormElementSetValue ($searchfld, $searchW)
    $searchfld.Select
    send("{enter}")
    _IELoadWait ($oIE)

    $oTable = _IETableGetCollection ($oIE, 0)
    $aTableData = _IETableWriteToArray ($oTable)

    $gasprice=""
    $gaspricep = $aTableData[1][3]
    $gasprice=StringReplace($gaspricep, "p", "")
    $excel.cells($row,10)=$gasprice/100

    $dslprice=""
    $dslpricep = $aTableData[2][3]
    $dslprice=StringReplace($dslpricep, "p", "")
    $excel.cells($row,11)=$dslprice/100
    $row=$row+1
    _IENavigate($oIE,"http://www.petrolprices.com/")
    _IELoadWait ($oIE)
Until $row=$rowx+1

Cheers, and thanks for the help guys!
