Regex result problem

3 posts in this topic

Hi,

I´m writting from Portugal, so sorry for my bad english

I have searched in the forum, and i couldn´t find the answer to my problem.

I´m trying to get some information from the html code of a web page.

I Want to obtain the tag id (in this case = f3). The page has other div tags, this is only one small piece of the html code.

The tag id could vary from f1 to f6.

<div id="f3">

after some hours, i have reached to this:

this works fine, the id is displayed in the array

$oDivs = _IETagNameGetCollection($IE_Browser, "DIV")

For $oDiv In $oDivs

$aRegEx = StringRegExp($oDiv.id, 'f[1-6]', 3)

_ArrayDisplay($aRegEx)

Next

I need to use the variable in a following part of the code, But when i run this i get a ERROR:

$oDivs = _IETagNameGetCollection($IE_Browser, "DIV")

For $oDiv In $oDivs

$aRegEx = StringRegExp($oDiv.id, 'f[1-6]', 3)

MsgBox(0, "Result", $aRegEx[0])

Next

This is the ERROR:

Subscript used with non-Array variable.:

MsgBox(0, "Result", $aRegEx[0])

MsgBox(0, "Result", $aRegEx^ ERROR

I´m confused

Coud someone help me

$oDivs = _IETagNameGetCollection($IE_Browser, "DIV")
For $oDiv In $oDivs
  $aRegEx = StringRegExp($oDiv.id, 'f[1-6]', 3)
  If NOT @error Then
    MsgBox(0, "Result", $aRegEx[0])
  EndIf
Next

Read about "Return Error" in StringRegExp() reference.

The error is displayed because StringRegExp() doesn't return an array when doesn't match with the pattern.
