XPath Toolbar

XPath Toolbar

Oxygen XML Developer provides an XPath toolbar to let you query XML documents fast and easy using XPath expressions.

XPath Toolbar

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 Developer 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 Developer can return a compilation error.

XPath scope menu

Oxygen XML Developer 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.
• 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.

Switch to XPath Builder View

Opens the XPath Builder view.

Settings menu

The following actions are available in this drop-down menu:

• Update on cursor move - When enabled and you navigate through a document, the XPath expression corresponding to the XML node at the current cursor position is displayed.
• Evaluate as you type - When you select this option, the XPath expression you are composing is evaluated in real time.

  Note

  The Evaluate as you type option and the automatic validation are disabled when you edit huge documents or when the scope is other than Current file.
• Options - Opens the Preferences page of the currently selected processing engine.
