Elements are the core data items in XML and can be nested, so an element can have children in the tree structure.Attributes, on the other hand, are simple data values that are attached to elements.XPath uses the / (forward slash) character to separate individual elements on the path just like Linux and Mac OS use that character to separate directories.Interestingly, this analogy to directory paths also holds for two very common abbreviations in XPath: just like a single period .In the trees under Page Sources you will see that attributes are shown with an = (equal sign) before their name.That’s because in an XML document, attributes are written as, e.g., color=”green”.If you know how to write formulas in an Excel spreadsheet, you can easily learn how to write XPath formulas or expressions in Mobile Together. The XPath builder in Mobile Together makes it easy to construct XPath expressions, just like the formula builder in Excel helps you with writing formulas in your spreadsheets.

What you really want to do is to select some of the data that matches a certain criteria in order to, e.g., show it in a graph or present it to the user in a table.
