The XPath monitor you find in the menu Extras is a tool for users who have at least basic knowledge of XPath.
These users will know and appreciate the possibilities that this monitor offers them. We will only explain the general function of this monitor for users without knowledge of XPath here.
XPath is a language for addressing parts of an XML document.
If you have already loaded an XML file you will see the XML structure in the monitor. An XPath expression is entered in the field XPath Expression and the XML structure level from which the expression is supposed to be applied is selected. It is also possible to drag nodes from the XML file into the window. The context menu also offers some XPath expressions to choose from. During typing the syntax is checked and mistakes are highlighted.
The process is started with the button "Evaluate"; the results are shown in the field Result. "Close" shuts the window.
More information on XPath expressions and their syntax can be found in the relevant technical literature.
