XML stands for Extensible Markup Language and is used for many data integration purposes. The basics of XML are built from lines of code that contain a tag and data. A tag is something that identifies what the data is, like a label. <invoiceNumber> for example would be a tag identifying the data of an invoice number. Tags open and close, containing the data they are labelling. So in an XML invoice file, you might see:
Each tag represents a field of data that can be used to communicate information.
