Detection Settings - Identify XML File Type by Content

The Detection page allows you to use any combination of the following XML items to identify a file type:

Root elements

One or more names used for the root element, for example my_root.

DOCTYPE declaration

For example:

 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

xsi:schemaLocation

A URL used to specify the schema location. This matches schemaLocation or no NamespaceSchemaLocation attribute in the file.

xmlns: declaration

One or more namespace URLs.

XPath rules

One or more XPath rules.

Example - Specifying a root element

To specify a root element use the element name (no angle brackets), for example:

email

With this, the SDL file support software will match any XML file that has the root <email>, for example:

<email>
	<sendto> John Brown </sendto>
</email>

Example - Specifying a schemaLocation URL

If you provide a schemaLocation: http://www.sdl.com/xml/SdlExample.xsd, then the SDL file support software will match any XML file that uses either of the following schemaLocations:

xsi:schemaLocation="http://www.sdl.com/xml/SdlExample.xsd"

xsi:noNamespaceSchemaLocation="http://www.sdl.com/xml/SdlExample.xsd"

Example - Specifying a namespace URL

If you provide a namespace http://www.w3.org/1999/ xhtml, then the SDL file support software will match any XML file that includes <html xmlns="http://www.w3.org/1999/ xhtml">

Example - Specifying multiple root elements

If you specify two root elements, for example:

email
post

Then both the following XML files will match the new file type:

<email>
	 <sendto>Mary Brown</sendto>
</email>

<post>
	 <sendto>John Brown</sendto>
</post>

Example - Specifying any XML document

If you provide a root element name

(that is, an asterisk), any XML document will match this file type. Usually, if you have such a catch-all specification, you would position it at the bottom of the list of XML file types, so that more specific specifications take precedence.
