How can I remove brackets from payload in mule ESB?

Question

Currently I have a payload with brackets and with a , to separate each of the rows. The idea is to remove the [ at the beginning and the ] at the end, as well as , in the middle

Are there any idea?

my comment is too long to be posted in comment section so rather posting here.

this is how your payload is looking.

after every comma there is a new xml that start, so you cannot embed multiple xml's under one xml unless what you are trying is to have multiple rows of data in xml.

the first thing that you want to do is to convert your input into a well-formed XML currently it is not. look at all these , <?xml version="1.0" encoding="UTF-8"?> in your payload makes it junk.

the following code will do what you are looking for

<?xml version="1.0" encoding="UTF-8"?>

and produces the following output but as stated the output xml is still an invalid xml and you might want to revisit how your payload is actually getting formed at source and you might want to correct it.
