XML Configuration Record Document Type Definition

An XML document type definition (DTD) is a description of the structure and content of an XML document. It verifies that a document is valid. XCRs are exported using the DTD as shown in Figure A-3 DTD for XCRs.

The xPico Wi-Fi DTD rules state the following:

The XML document element is a <configrecord> element. This is the root element.

A <configrecord> must have one or more <configgroup> elements and can have a version attribute.

A <configgroup> must have one or more <configitem> elements and can have name and instance attributes.

A <configitem> element must have one or more <value> elements and can have a name attribute.

A <value> element can have only data and can have a name attribute.

The name attribute identifies a group, item, or value. It is always a quoted string.

The instance attribute identifies the specific option, like the serial port number. The "instance" attribute is always a quoted string.

Note:

The name for each <configgroup> (specified with the name attribute) is the group name listed in the Web Manager XCR groups or with the "xcr list" CLI command. See the xPico Wi-Fi Embedded Device Server User Guide for more information about the XCR groups.
