IntelliJ IDEA 2023.2 Help

Schemas and DTDs

The settings on this page define how your XML, HTML and XHTML files are validated.

External Schemas and DTDs

Local XML schema (XSD) and DTD files that are used to validate your XML files are listed in this section.

Each entry is a mapping of a URI that may be referenced in your XML file onto an appropriate local schema or DTD file. Use Add, Remove and Edit to create, remove and edit the mappings. See also, Referencing XML schemas and DTDs.

Description

URI

A URL of an XML schema (XSD) or DTD file (for example http://www.example.org/xsds/example.xsd) or a namespace URI (for example http://www.example.org, urn:jboss:domain:1.0). Readonly.

If an XML file references the specified URI, it's validated according to a local file whose path is shown in the Location columns.

Location

Path to corresponding local XSD or DTD file (readonly).

Project

If a checkbox is not selected, a mapping is available in all of your projects.

Select the mappings that you want to be available only in the current project.

The selected mappings are stored in .idea/misc.xml or the project .ipr file. These files are normally shared between development team members through version control.
