op.xmlElement

op.xmlElement(
   name as String,
   [attributeValue as attributeNode],
   [childContent as String]
) as elementNode

Summary

This function constructs an XML element with the name (which can be a string or QName), zero or more attributes, and child content. The child content can include a sequence or array of atomic values or an element, comment, or processing instruction nodes. Atomic values are converted to text nodes.

Parameters
name	The string or QName for the constructed element.
attributeValue	Any element attributes returned from op.xmlAttribute, or `null` if no attributes.
childContent	A sequence or array of atomic values or an element, a comment from op.xmlComment, or processing instruction nodes from op.xmlPI.

Example

const op = require('/MarkLogic/optic');

const literals = op.fromLiterals([
            {row:1, gp: 1, nm:"alpha", str:"a", num:10, bool:true},
            {row:2, gp: 1, nm:"beta", str:"b", num:20, bool:false},
            {row:3, gp: 2, nm:"gamma", str:"c", num:30, bool:true},
            {row:4, gp: 2, nm:"delta", str:"d", num:40, bool:false}
	          ])
literals.where(op.eq(op.col('gp'), 1))
        .select(['row',
                 op.as('node',
                       op.xmlDocument(
                          op.xmlElement(op.col('nm'),
                                        null,
                                        op.xmlElement(op.col('str'),
                                        null,
                                        op.xmlText(op.col('bool')))
	                       )
	                )),
                 op.as('kind', op.xdmp.nodeKind(op.col('node')))
               ])
        .orderBy('row')
        .result();
