Seperate XML content from a single XML file using XQuery - xpath

Question

I have a XML file which contains multiple XML nodes. I would like to separate two XML notes and store them in separate variables. How would I write this functionality with XQuery? I have added my XML file below. Inside the XML file I have a division root element, Dive and top-song are two child elements. Now I want to read the Dive XML content in one variable and top-song content in another variable. Can any one please help me to sort out this issue?
<?xml version="1.0" encoding="UTF-8"?>

Answer 1

It's not clear what you're trying to accomplish on a high level, but you can select those elements with some simple XQuery/Xpath:
let $dive := doc('mydoc.xml')/division/Dive
let $top-song := doc('mydoc.xml')/division/top-song
However, just looking at the document it's clear that these two elements are in totally unrelated schemas, and as a general recommendation for MarkLogic, they should probably each be separated before ingestion and inserted as separate documents.
