Before you start working with XSLT, make sure that XPath View+XSLT Support plugin is enabled.
The plugin is bundled with IntelliJ IDEA and activated by default. If it is not, enable the plugin.
- XSLT support is available in all XML files that declare the XSLT-Namespace http://www.w3.org/1999/XSL/Transform on their root element.
- IntelliJ IDEA supports XSLT 2.0 and XPath 2.0 syntax.
- A XSLT 2.0 capable processor (e.g. Saxon 9-HE) should be added to the classpath of a module that is used to run a stylesheet, and placed in front of JDK. Refer to the section Processing Order.
The plugin allows you to:
- Evaluate expressions against the currently focused document, including support for the document() function to make cross-document queries
- Evaluate an expression against multiple XML documents in a Find in Path style way by the new Find by XPath action.
The Expression Evaluation dialog allows you to highlight matching expressions in the current editor or to open the Find tool window to display a list of matching lines. Editing XPath expressions is enhanced by on-the-fly error-checking including a set of customizable XPath Inspections and a wide range of code completion suggestions.
The plugin also offers a way to display a unique XPath expression for a selected element in an editor. This is available via Main Menuin the
XSLT support is not limited to XPath expressions, it also supports a wide range of XSLT constructs, like checking the existence of templates that are called via xsl:call-template and their parameters, refactoring and navigation enhancements. Find out more about this in the XSLT Support section.
