XML

XML is a flexible and sometimes overuised data format. However as a programmer, you will interact with it. here are some things I've learned on XML and how to use it

• Adding a subnode to an XML file - Usingt xmlstarlet you can add a subnode to a node on the command line.
• Adding an attribute to an XML node in an XML file on the command line - Usingt xmlstarlet you can add an attribute to many XML nodes on the command line
• Delete an XML node from an XML file on the command line - Usingt xmlstarlet you can delete one or many xml nodes from an xml document on the command line
