You can navigate your way through the document using the XMLnavigate wrapper
directly, although you will still need to hand-hold the exchange object to
actually do any work importing or exporting to the document. Here's a code
snippet that might help show a simple loop through the nodes of a DOM:
cImpXMLNavigator &= cImpExch.getNavigator()
cImpXMLNavigator.goToRoot()
bImpXmlRet = cImpXMLNavigator.goToFirstChild()
Loop
If bImpXmlRet <> CPXMLErr:NoError
Break
End
If cImpXMLNavigator.getNodeName() = 'Orders'
cImpXMLNavigator.setXMLExchangeNode()
! Set the node back into the Exchange object
bImpXmlRet = cImpExch.FromXML( cImpWrapperOD )
!And read in the set of OrderDetails for this order
If bImpXmlRet <> CPXMLErr:NoError
Message( 'An Error Occurred while Converting the XML Input. ' &|
'The error returned was: ' & bImpXmlRet,|
'Error Converting XML Output',|
ICON:Hand, BUTTON:OK )
End
End
bImpXmlRet = cImpXMLNavigator.goToNextSibling()
End
cImpExch.Close()
