XSLT 3.0 in Visual Studio Code

Visual Studio Code with DeltaXML’s XSLT provides a comprehensive set of language features for XSLT 3.0. This page outlines how these language features can be used to help you work with XSLT more effectively.

Syntax Highlighting

Accurate and responsive syntax highlighting for XSLT and XPath expressions is provided by a hand-crafted semantic token provider. Code is processed character by character, avoiding the unpredictable behaviour of line by line regex based tokenisers on the most complex expressions.

Syntax highlighting is currently only enabled by default in VSCode's built-in themes. This is because some extension themes may not yet have specific language support for VSCode's 'Semantic Highlighting' as used by this extension.

To enable syntax highighting for a custom theme you need to change User Settings. For example, to enable syntax highlighting for XSLT in the City Lights theme use:

{
    "editor.semanticTokenColorCustomizations":{
      "[City +Lights]": {"enabled": true}
    },
}

Or, to enable syntax highlighting for all themes:

{
    "editor.semanticTokenColorCustomizations":{
      "enabled": true
    },
}
