Code completion in XSLT

Last modified: 21 June 2022

With Code Completion being one of the key features of PhpStorm, the plugin provides several possibilities to complete keywords, predefined functions, variables, and parameters used in XPath expressions, template names and names of parameters that can be passed to a template invocation.

Before you start

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

Completion In XPath Expressions

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.

Function Completion

The Quick Documentation Lookup also works in completion lookup lists.

Completion For Template Names In Xsl:call-Template

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.

Template Name Completion

Completion For Template Parameters

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.

Parameter Completion

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 which is required according to the schema; for example,

<xsl:with-p <ctrl-space>

=>

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