Configuration Using XML
The PremierWave XC intelligent gateway provides an Extensible Markup Language (XML)
interface that you can use to configure PremierWave XC devices. Every configuration setting that
can be issued from the intelligent gateway Web Manager and CLI can be specified using XML.
The intelligent gateway can import and export configuration settings as an XML document known
as an XML Configuration Record (XCR). An XCR can be imported or exported via the CLI, a Web
browser, FTP, or the PremierWave XC filesystem. An XCR can contain many configuration
settings or just a few. For example, it might change all of the configurable parameters for a
intelligent gateway, or it may only change the baud rate for a single serial line. Using XCRs is a
straightforward and flexible way to manage the configuration of multiple PremierWave XC devices.
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 4-1 DTD for XCRs
.

<!DOCTYPE configrecord [
<!ELEMENT configrecord (conf)>
<!ELEMENT configgroup (con,configgroup*)>
<!ELEMENT configitem (value+)>
<!ELEMENT value (#PCDATA)>
<!ATTLIST configrecord version CDATA #IMPLIED>

The PremierWave device 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.
