[Lazarus] How to use GetElementById?

[silvioprog]

Hi guys,

I use the GetElementById in PHP with sucess, but in FPC I not know how use.

In PHP I use (with sucess):

...
$dom = new DOMDocument();
  @$dom->loadHTML($data);
  $return = @$dom->getElementById('currency_converter_result')
    ->getElementsByTagName('span')->item(0)->firstChild->wholeText;
...

In FPC I try (but without sucess):

...
var
  VHTMLDocument: THTMLDocument = nil;
begin
  try
    ReadHTMLFile(VHTMLDocument, '../HTML/index.htm');
    ShowMessage(VHTMLDocument.GetElementById('currency_converter_result'
      ).GetElementsByTagName('span').Item[0].FirstChild.TextContent);
...

I found a 'generic' solution:

....

ShowMessage(VHTMLDocument.GetElementsByTagName('div').Item[5].TextContent);
// This is a unique alternative? :o
....

Any idea? The GetElementById function works? :/

Project to reproduce my problema in attached (with the HTML and PHP files).

( sorry for my bad english ^^' )

Thanks.
