Can i use 'xmldump_load' in mysql 5.0.51?

[kanokwan cctek]

hello all,
I'm trying to put xml files into 'mysql version is '5.0.51b'from the code below
but the error is >>ERROR 1064 (42000): You have an error in your SQL syntax;check the manual that corresponds to your MySQL server version for the right syntax to use near ''/esp/bin/stmcode.xml','testdb','stmcode' at line 1<<

Please give me the suggestion.
