Com error with DOM

[AutoitMike]

I have a simple function to open an xml file and read a node value.

Every other time the function _XMLFileOpen() is encountered, I get "Com Error with DOM". This looks like a file close is not occuring, however, there is no file close function in the _XMLwrapper.au3

EG:

#include <_XMLDOMWrapper.au3>

#include <Array.au3>

$Node="StartTime"

$sXmlFile = "C:UsersMikeDocumentsreport.xml"

$sXPath = "//ReportInfo/prop[@name='" & $Node & "']"

_XMLFileOpen($sXmlFile)

If @error Then

MsgBox(0,"","error")

EndIf

$aRET = _XMLGetValue($sXPath)

_ArrayDisplay($aRET, "")

Even when encountering the error , the node value is still returned, obtained.

The error code is 0000000

If I exit my program, restart it, no error is encountered the first time

Any ideas????

Thanks

Add a COM error handler to your script to get maximum information about what happened.

Please have a look at ObjEvent in the help file for how to set up a COM error handler.

I get the error trapped, all I can see is that it is error 000000

However,

I noticed that once the file is open within a running script, I do not need to re open. However, I guess I need to keep track, set a flag that it is open????

There should be a function to test if it is open, or a function to close it. This is what the "Norm" seems to me after 40 + years of programming.

What is the return value of _XMLFileOpen? I guess a handle to the file. So this is your flag that indicates that the file is open.

Is there any way to close an open xml file?

I made a script that needs to move the file to a new folder and since it was open, the move command did not work.

Looks like you need to release Global variable $objDoc

$objDoc = 0

Thanks for the tip, but releasing $objDoc did not work

¿any other suggestions?

I've never worked with XML myself but I remember there was another thread on this subject recently.

Search the forum and you'll find what you need.

Sorry for the delay, I had no time to test other options and was involved in other things.

$objDoc = 0 indeed closes the file when it is open by the script, tested in another script and works fine.

What I think is happening is that another application that I send the xml file to is locking it, so I can not move it.

Solved this by moving the file first and then sending it to the application.

Thanks for your help and time
