The one way is to use %XML.TextReader

ClassMethod Reader(str, pth, ByRef val)
{
	kill val
	set val=0
	// Adjust the method name below to your needs
	// ParseString(), ParseStream(), ParseFile() 
	if ##class(%XML.TextReader).ParseString(str,.rdr) {
		while rdr.Read() {
			if rdr.NodeType="chars",rdr.Path=pth set val($i(val))=rdr.Value
		}
		quit 1
	}
	quit 0
}

set str="<?xml version=""1.0"" encoding=""UTF-8""?><Input><data><Ids><Id><Type>A</Type><Value>123</Value></Id><Id><Type>B</Type><Value>456</Value></Id></Ids></data></Input>"
write ##class(yourClass).Reader(str,"/Input/data/Ids/Id/Value",.val) --> 1
zw val -->
val=2
val(1)=123
val(2)=456

The other way is to use %XML.Reader() and correlate to a class which describes your XML structure
