[basex-talk] XQuery to insert nodes in XML File

Dear Team,

I am trying to insert few nodes in a XML File. But in reality the nodes are not inserting in the XML File!!

Below is my query

for $x in doc('C:\sample.xml')//CInfos return insert node <Info><Name>James Stuart</Name><Key>7709422869</Key></Info> as last into $x

I tried with another query -

insert node <Info> <Name>James Stuart</Name> <Key>7709422869</Key> </Info> as last into doc('C:\sample.xml')//CInfos

This too not working

If I create a XML DB and then it works... What am I missing?
