Thanks for the update. Unfortunately, I'm still seeing the same
symptoms.

The only version of php that seems to work with the getAttribute of
MSXML is 4.3.2RC1.

I've start porting the code to use the PHP DOM model, and that seems to
work better.

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?

Jim
