Table elements are a bit tough to use as elements without a custom UDF.

There was one made to parse out table elements in scraps a long time ago, but I am not sure if it would even be helpful, after all the customizations you would have to do.

First off, you can use the new obj/com to get the part of the web page you want (full, form,etc.)

Next, you will have to look at the HTML, and do your parsing.

You could make up an array with all the table elements. I use elements very loosely, and actually I don't think HTML tables have elements. (elements=links,form parts, images, etc)

A new table part will start with <td or <tr

If you wanted an array, you could do it mickeymouse style via something like this:

$array=stringreplace($HTML,"<td",)

$array=stringreplace($array,"<tr",)

$array=stringsplit($array,)

then you can remove a bit of the formatting, because many parts will look like this:

>start of table stuff</td>

or

colspan=2 width="203" hieght=30%>more table stuff</tr>

You basically have to understand HTML to do this quickly. If not, maybe you can look for that HTML Table UDF and dump the HTML from the page in, and hook up a little search.

Frames, and IFrames are a quite different animal.

cheers scriptkitty,

I'll probably search/parse the HTML myself. From looking at how to access form elements i thought it may have been 'that' easy.

Thanks for your help! - read some of your previous posts about IE too - very helpful.

<{POST_SNAPBACK}>

The DOM doesn't have a TABLE collection in the same way that it has, for example, a FORM collection -- however, there is another way to attack it.

getElementsByTagName(tag) will create a collection of all elements of that tag.

.innerHTML will allow you to retrieve the contents of that tag.

Here are a couple of sites with a bunch of Javascript examples and I'll include a couple of au3 examples below.

HTML DOM Table Object

Traversing an HTML table with Javascript and DOM Interfaces

This example parses the each table on the page and writes the contents of each TD element to the console:

$ObjIE=ObjCreate("InternetExplorer.Application")
With $ObjIE
  .Visible = True
  .Navigate("http://www.autoitscript.com/")

  while .ReadyState <> 4
    Sleep(50)
  wend
EndWith

$document = $objIE.document
$body = $document.getElementsByTagName("body").item(0)
$tables = $body.getElementsByTagName("table")

For $table in $tables
    $rows = $table.getElementsByTagName("tr")
    For $row in $rows
        $tds = $row.getElementsByTagName("td")
        For $td in $tds
        ; Display the HTML contents of each cell...
            ConsoleWrite($td.innerHTML)
        Next
    Next
Next

Exit

This example is nearly the same, but it only parses the first table in the document:

$document = $objIE.document
$body = $document.getElementsByTagName("body").item(0)
$table = $body.getElementsByTagName("table").item(0)
$rows = $table.getElementsByTagName("tr")

For $row in $rows
    $tds = $row.getElementsByTagName("td")
    For $td in $tds
    ; Display the HTML contents of each cell...
        ConsoleWrite($td.innerHTML)
    Next
Next

Exit

There are lots of possibilities here...
