FleXML is a free Chrome add-on developed by luislag1110 that allows users to navigate XML files more efficiently and view them in style. With three available themes - Classic, Dark, and Light - users can customize their viewing experience to suit their preferences.

One of the key features of FleXML is the ability to collapse or expand nodes with simple commands. To collapse child nodes, users can CTRL+LEFT_CLICK on a node, while ALT+LEFT_CLICK allows them to expand child nodes. Similarly, CTRL+DOUBLE_LEFT_CLICK collapses sibling nodes, and ALT+DOUBLE_RIGHT_CLICK expands sibling nodes.

It's worth noting that if users want to use this extension for local files, they need to enable access to file URLs in the extension settings. This can be done by navigating to chrome://extensions, clicking on the details of the FleXML extension, and toggling the "Allow access to file URLs" setting to ON.

With its user-friendly interface and convenient navigation features, FleXML is a valuable tool for anyone working with XML files.
