Default Replace in All Descendant XML Nodes

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


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!
replaceAllInXML: Recursively iterates through all descendant nodes of an E4X XML object and makes a string replacement.

This is useful if you want to make a global replacement in your message but only want to do it for a specific connector. Obviously you can do this in a preprocessor, but if you only want it to happen for a single destination, this function will allow you do to that easily.

  • parent: The node to recursively iterate through.
  • regexp: The regular expression to test against at each leaf (text) node. This should be a RegExp object, like "new RegExp('foo','g')" or "/foo/g".
  • replacement: The string with which to replace.

  • Replace all single quotes (') with two single quotes (''), e.g. to prepare for inserting into a database:
  • If any dates occur in a PID or OBR segment that do not have the hour/minute/second defined (i.e. it's only yyyyMMdd, like "20130206"), then add on the HHmmss ("000000"). This might be used to send to a system that requires those date fields to be in the full yyyyMMddHHmmss format.
    for each (seg in msg.*.(function(){return/PID|OBR/.test((new XML(this)).name())}()))

The code:

function replaceAllInXML(parent,regexp,replacement) {
	for each (child in parent.children())
		if (child.hasComplexContent())
			parent.children()[child.childIndex()] = child.toString().replace(regexp,replacement);

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.
