Customize Error when failing to load an XML document

When I attempt to load an XML document such as
xmlDoc.Load('\\Server\Shared\NavData_Public\Testing\' + cuCPUtils.UserBatch() + 'BOT2.xml') sometimes it may error because the document isn't always XML friendly. I see an error like
Microsoft Dynamics NAV

This message is for C/AL programmers: A call to System.Xml.XmlDocument.Load failed with this message: Unexpected end tag. Line 2, position 3.

OK

I thought you'd be able to do something like

IF xmlDoc.Load('\\Server\Shared\NavData_Public\Testing\' + cuCPUtils.UserBatch() + 'BOT2.xml') TRUE THEN BEGIN but this is void. Is there any other way to display my own message when this occurs?
