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 , and to create, remove and edit the mappings. See also, Referencing XML schemas and DTDs.

Item	Keyboard Shortcut	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.
	`⌘ N`	Use this icon or shortcut to open the Map External Resource Dialog to define a new mapping between a URI and a local file.
	`⌥ ⌦`	Use this icon or shortcut to remove the selected mappings from the list.
	`⏎`	Use this icon or shortcut to edit the selected mapping in the Map External Resource Dialog.

Ignored Schemas and DTDs

URIs for ignored schemas and DTDs are listed in this section. (If an XML file references a URI listed in this section, AppCode ignores that URI and doesn't mark it as an error in the editor.) Use , and to add, remove and edit the URIs. See also,Referencing XML schemas and DTDs.

Item	Shortcut	Description
	`⌘ N`	Use this icon or shortcut to add a new URI to the list.
	`⏎`	Use this icon or shortcut to edit the selected URI.
	`⌥ ⌦`	Use this icon or shortcut to remove the selected URIs from the list. The corresponding URIs become available for mapping to local XSD or DTD files.
