Example 1
Retrieval of the reference of the first XML element of the parent root. The XML structure (C:\\import.xml) is first loaded into a BLOB:
var myBlobVar : Blob
var $xml_Parent_Ref;$xml_Child_Ref : Text
DOCUMENT TO BLOB("c:\\import.xml";myBlobVar)
$xml_Parent_Ref:=DOM Parse XML variable(myBlobVar)
$xml_Child_Ref:=DOM Get first child XML element($xml_Parent_Ref)
Example 2
Retrieval of the reference, name and value of the first XML element of the parent root. The XML structure (C:\\import.xml) is first loaded into a BLOB:
var myBlobVar : Blob
var $xml_Parent_Ref;$xml_Child_Ref : Text
var $childName;$childValue : Text
DOCUMENT TO BLOB("c:\\import.xml";myBlobVar)
$xml_Parent_Ref:=DOM Parse XML variable(myBlobVar)
$xml_Child_Ref:=DOM Get first child XML element($xml_Parent_Ref;$childName;$childValue)
