XPath Toolbar
XPath is a query language for selecting nodes from an XML document. To use XPath expressions effectively, you need a good understanding of the XPath Core Function Library.
XPath Toolbar
Oxygen XML provides an XPath toolbar to let you query XML documents fast and easy using XPath expressions.
The XPath toolbar includes the following features:
- XPath version chooser drop-down menu
-
You can choose the XPath version from the drop-down menu available in the left side of the toolbar. Available options include XPath 1.0, XPath 2.0, XPath 2.0 SA, XPath 3.1, XPath 3.1 SA.
Note:The XPath 2.0 SA and XPath 3.1 SA options have some limitations. These options only offer information about the beginning part of the matching result. For example, if you search for an element, it will only highlight the start tag.Warning:Oxygen XML uses Saxon to execute XPath 3.1 expressions, but implements a part of the 3.1 functions. When using a function that is not implemented, Oxygen XML can return a compilation error. - History drop-down list
- The XPath combo box keeps a history of the last 15 expressions that were used so that you can easily choose them again.
