Default Strip Empty Nodes from XML

Quote:
UPDATE: I've created a public GitHub repository to track these example channels, code templates, scripts, or whatever else!

https://github.com/nextgenhealthcare/connect-examples

To start with I only added the ones I wrote, because I didn't want to presume and add code from others without their explicit permission. Pull requests welcome!
stripEmptyNodes: Recursively iterates through all descendant nodes of an E4X XML object and removes those that are empty (or those whose children are all empty).

Parameters:
  • node: The node to iterate through. If node itself is empty, it will not be removed from its parent.

Examples:
  • Get rid of all empty nodes in the inbound XML structure (msg):
    Code:
    stripEmptyNodes(msg);

The code:

Code:
function stripEmptyNodes(node) {
	var name = '', index = -1;
	for each (child in node.children()) {
		index = (name != child.name() ? 0 : index+1);
		name = child.name();
		stripEmptyNodes(child);
		if (!child.toString())
			delete node[child.name()][index];
	}
}

Always include what Mirth Connect version you're working with. Also include (if applicable) the code you're using and full stacktraces for errors (use CODE tags). Posting your entire channel is helpful as well; make sure to scrub any PHI/passwords first.


- How do I foo?
- You just bar.
