Extract the parts from a multipart encoding. The first item in the sequence is a manifest, and the remaining items are the decoded parts.
An attempt will be made to determine the type of content based on headers such as the part's content-type. If possible, an element will be returned, falling back to an xs:string, and finally binary().
The options control how the parts are unpacked, and are similar to xdmp:zip-get - default-namespace, repair, format, default-language, and encoding. The options apply to all parts, so specifying a format of binary will cause all parts to be returned as binary, and specifying text will cause all parts to be returned as xs:string if possible, falling back to binary() if necessary. This is useful if different parts need different options, in which case the resulting strings can each be passed to xdmp:unquote() with appropriate options.
var html = xdmp.unquote('<html><p>Some stuff in an .html document</p></html>')
.next().value;
var xml = xdmp.unquote('<root> \n\
<a>Some other stuff in a .xml document</a> \n\
</root>').next().value;
var json = xdmp.toJSON(["a",false]);
var boundaryString = "gc0p4Jq0M2Yt08jU534c0p";
var manifest = xdmp.unquote(
'<manifest>'
+ '<part><headers>'
+ '<Content-Type>application/xml</Content-Type>'
+ '<boundary>gc0p4Jq0M2Yt08jU534c0p</boundary>'
+ '</headers>'
+ '</part>'
+ '<part><headers><Content-Type>text/html</Content-Type> </headers></part> '
+ '<part><headers><Content-Type>application/json</Content-Type></headers></part>'
+ '</manifest>').next().value.root
var mpe = xdmp.multipartEncode(
boundaryString,
manifest,
[xml,html,json] );
xdmp.multipartDecode(boundaryString, mpe);
