But when trying to assign that value I only get data, without the tags, I tried parsing it using

JSON.stringify

but didn’t work, any idea, what I want to do is get some values from that xml so I though about using

nlapiStringToXML

but I got an error saying

Content is not allowed in prolog

This is what I tried :

nlapiStringToXML(JSON.stringify(xmlLookup.custrecord_bit_file_content))

Content is not allowed in prolog

your error suggests that you aren't passing xml to be parsed

Yes, you are right, I was trying to use `nlapiStringToXML`just to have better access, but using `slice()`directly on the string gave me the same result!! Thanks @battk!!
