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 Author 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 3.0, XPath 3.0 SA.
Note
The results returned by XPath 2.0 SA and XPath 3.0 SA have a location limited to the line number of the start element (there are no column information and no end specified).Warning
Oxygen XML Author uses Saxon to execute XPath 3.0 expressions, but implements a part of the 3.0 functions. When using a function that is not implemented, Oxygen XML Author can return a compilation error. - XPath scope menu
- Oxygen XML Author allows you to define a scope for which the XPath
operation will be executed. You can choose where the XPath expression will be executed:
Current
file - Current selected file only.
Project - All the files in
the project.
Selected project
resources - The files selected in the project.
All opened
files - All files opened in the application.
Current DITA Map hierarchy
- All resources referenced in the currently selected DITA map, opened in the
DITA Maps Manager view.
Opened
archive - Files open in the Archive Browser view.
Working
sets - The selected working sets.
At the bottom of the scope menu the following scope configuration actions are available:
Configure XPath
working sets - Allows you to configure and manage collections of
files and folders, encapsulated in logical containers called working
sets.
XPath file filter
- You can filter the files from the selected scope for which the XPath expression
will be executed. By default, the XPath expression will be executed only on XML
files, but you can also define a set of patterns that will filter out files from
the current scope. If you select the
Include archive option, the XPath expression will be
also executed on the files in any archive (including EPUB and DocX) found at the
current scope.
- 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.

are composing is evaluated in real time.
