You can use xmlstarlet to update your template.xml(which is ill-formed)

$ cat template.xml 
<employee>
 <name>##name##</name> 
 <id>##empid##</id>
</employee>

$ xmlstarlet ed -u //name -v emp2 -u //id -v 2 template.xml 
<?xml version="1.0"?>
<employee>
  <name>emp2</name>
  <id>2</id>
</employee>
