Code completion in XSLT

Install and enable the XPathView + XSLT plugin on the Settings | Plugins page, tab Marketplace, as described in Installing plugins from JetBrains Marketplace.

It's possible to complete all parameters/variables in scope inside an XPath expression in a normal expression attribute or inside an attribute value template

Also, all predefined functions and keywords are available for completion, including function signatures.

The Quick Documentation Lookup also works in completion lookup lists.

The template's name that is to be called can be completed from a list of all named templates in the current document and included Style Sheets.

There's a special completion for parameters that should be passed to a template in a xsl:call-template invocation. The completion lists all parameters that are declared by the template and are not yet present in the argument list of the invocation, it means there's no xsl:with-param yet.

tip

That's especially useful when also using completion to create the xsl:with-param tag, because this will automatically trigger the completion for the parameter's name that is required according to the schema; for example,

<xsl:with-p <ctrl-space>

=>

<xsl:with-param name="[lookup list]"
