The code for retrieving Keywords is as below:

Set objGovCat = TDSE.GetObject(emField("EmbeddedFieldURI").Value(1) , 1) 
Set lStrXml = GetNewDomDocument()
lStrXml.loadXML(objGovCat.GetListKeywords(3))

Answer 1

Publishing is fixed after passing XMLListIDAndTitle in to GetListKeywords method so the updated code is now

Set objGovCat = TDSE.GetObject(emField("EmbeddedFieldURI").Value(1) , 1) 
Set lStrXml = GetNewDomDocument()
lStrXml.loadXML(objGovCat.GetListKeywords(XMLListIDAndTitle))
