I just tried PHP 4.3.2RC4, and see the same problem

Hello

I am running Windows 2000 SP3, Apache 2.0.45, and PHP 4.3.2RC3. When I
try to use the getAttribute method of MSXML, I get the following error
message:

Warning: (null)(): Invoke() failed: Exception occurred. Source:
Unavailable Description: Unavailable in C:\Apache2\htdocs\get_xml.php
on line 198

Line 198 is where the getAttribute is called. However, this code works
perfectly with PHP4.3.2RC1.

Following is a snippet of the php code:

---------start code----------

    #create a new ModbusTCP object
    $MBObj = new ModbusTcp;

    #define the path to the web server files
    $serverpath = "c:\\Apache2\\htdocs\\";

    #define the path to point data
        $XMLPath = "ModbusTCP/Points/Point";

    #get the file name
    $xsltfilename = $filename;

    if ($xmltrue)
    {
        $xmlfile = $filename;
    }
    else
    {
         #load the xslt file into an array
        $xsltfile = file($serverpath.$xsltfilename);
        #get the xml file name
        $xmlfile = $xsltfile[0];
         #get the xsl file name
        $xslfile = $xsltfile[1];
        $xsl = new COM("Msxml2.DOMDocument");
        $xsl->async = false;
        $xsl->load($serverpath.$xslfile);
    }

    $xml = new COM("Msxml2.DOMDocument");

    $xml->async = false;
    $xml->load($serverpath.$xmlfile);

    $nodes = $xml->getElementsByTagName("ModbusTCP/IP");
    $node = $nodes->item(0);
    $ip = $node->text;

    $nodes = $xml->getElementsByTagName("ModbusTCP/UnitID");
    $node = $nodes->item(0);
    $id = $node->text;

    $nodes = $xml->getElementsByTagName("ModbusTCP/NumRegisters");
    $node = $nodes->item(0);
    $NumReg = $node->text;

    $nodes = $xml->getElementsByTagName("ModbusTCP/StartAddr");
    $node = $nodes->item(0);
    $Offset = $node->getAttribute("Offset");

-------end code-----------

Any ideas on what could be causing this?
