Everything that you develop in Boomi<\/a> (processes, maps, connectors, profiles, etc.) is a component and a component in Boomi is always represented (behind the pretty GUI) as a XML document.<\/p>\n

This means, that if you have made any change in a Boomi component, and wants to verify which change that you made, you can determine this by comparing two revisions of the ComponentXML<\/span> for the changed component. This will be a text<\/strong>-comparison and not a GUI-one, but with a little practice, it is easy enough to interpret.<\/p>\n

<\/p>\n

You can use whatever tool you want to compare the two revision. One suggestion is to use Notepad++<\/a> together with the Compare<\/a> plug-in. They work reasonably well.<\/p>\n

First you need to extract the ComponentXML<\/span> for the two revisions that you want to compare. This can be done both via the Website or by using the Boomi API<\/a>.<\/p>\n

The easiest (but least flexible) solution is to use the Website. In the bottom right corner, click on the “Revisions” link (marked with blue). This will show you a screen like this:<\/p>\n

\"Boomi<\/a>
Boomi Component Revisions<\/figcaption><\/figure>\n

This will show you all the different revisions of your component that you have saved. Everytime you click the save-button, a revision will be saved.<\/p>\n

Select two (often it will be the two top ones – which are also the newest two revisions), click on the ComponentXML<\/span> icon (marked with yellow). For each of these, you will see a result like this:<\/p>\n

\"Boomi<\/a><\/p>\n

The next step is to copy the two revisions to separate documents in your Notepad++. You cannot use Ctrl-A to mark the entire ComponentXML, since the xml is not shown in a real separate window, but only in a useless GUI-simulation of one. A suggestion is to mark the first part, scroll to the bottom and then, while holding down Shift button, click on the very end of the document.<\/p>\n

If you use another tool than Notepad++, you might need to save the two revisions in separate files, and then to open them in the compare tool of your choice.<\/p>\n

One annoying thing when comparing processes, is that their ComponentXML<\/span> contain a LOT of x=”47.1″ y=”52.2″<\/span>. These are simply the x\/y coordinates of lines etc. connecting different actions. For almost every case, they are irrelevant for the comparison, and they will often result in a lot of “noise” in the comparison, since it takes almost nothing to make them change between two saves of the process.<\/p>\n

Before you make the comparison, consider to replace ALL x\/y values with static values. If your editor supports using regular expressions<\/a> in search\/replace, you can:<\/p>\n
