When working with basic XML documents that do not have complex nested structures, it can sometimes be handy to extract a map of all the node names and their text values. This tag is a shortcut for that. It returns a map of every node that contains at least one non-empty text value.

Parameters

none

Sample Usage

[//lasso
	var('data') = string('\
<SOAP-ENV:Envelope 
	xmlns:SOAPSDK1="http://www.w3.org/2001/XMLSchema" 
	xmlns:SOAPSDK2="http://www.w3.org/2001/XMLSchema-instance" 
	xmlns:SOAPSDK3="http://schemas.xmlsoap.org/soap/encoding/" 
	xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
	
	<SOAP-ENV:Body SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
		<Item>
			<Quantity>1</Quantity>
			<Color>red</Color>
			<Size>small</Size>
			<Price>9.99</Price>
		</Item>
	</SOAP-ENV:Body>
</SOAP-ENV:Envelope>\
	');
	
	xml_nodemap($data);
]

Returns:

map: (Price)=(9.99), (Size)=(small), (Quantity)=(1), (Color)=(red)
