See the PremierWave XC User Guide for more information about the XCR groups.  An empty or missing element in each present clears the setting to its default. Quick Tour of XML Syntax Declaration The first line, , is called the XML declaration. It is required and indicates the XML version in use (normally version 1.0). The remainder of the file consists of nested XML elements, some of which have attributes and content. Element Start and End Tags An element typically consists of two tags: start tag and an end tag that surrounds text and other elements (element content). The start tag consists of a name surrounded by angle brackets, for example . The end tag consists of the same name surrounded by angle brackets, but with a forward slash preceding the name, for example . The element content can also contain other "child" elements. Element Attributes The XML element attributes that are name-value pairs included in the start tag after the element name. The values must always be quoted, using single or double quotes. Each attribute name should appear only once in an element. XML Example shows an XML example which consists of a declaration (first line), nested elements with attributes and content. Figure 4-2 XML Example disable The PremierWave XC uses the attributes in the following subsections to label the group configuration settings. PremierWave XC Command Reference 15

4: Configuration Using XML
PremierWave XC Command Reference
15
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 PremierWave XC User Guide for more information about the XCR groups.
An empty or missing <value> element in each present <configgroup> clears the
setting to its default.
Quick Tour of XML Syntax
Declaration
The first line,
<?xml version="1.0" standalone="yes"?>
,
is called the XML declaration.
It is required and indicates the XML version in use (normally version 1.0).
The remainder of the file
consists of nested XML elements, some of which have attributes and content.
Element Start and End Tags
An element typically consists of two tags: start tag and an end tag that surrounds text and other
elements (element content).
The start tag consists of a name surrounded by angle brackets, for
example
<configrecord>
.
The end tag consists of the same name surrounded by angle
brackets, but with a forward slash preceding the name, for example
</configrecord>
.
The
element content can also contain other "child" elements.
Element Attributes
The XML element attributes that are name-value pairs included in the start tag after the element
name.
The values must always be quoted, using single or double quotes.
Each attribute name
should appear only once in an element.
XML Example shows an XML example which consists of a declaration (first line), nested elements
with attributes and content.
Figure 4-2
XML Example
<?xml version=”1.0” standalone=”yes”?>
<configrecord>
<configgroup name = “serial command mode” instance = “1”>
<configitem name = “mode serial string”>
<value>disable</value>
</configitem>
</configgroup>
</configrecord>
The PremierWave XC uses the attributes in the following subsections to label the group
configuration settings.
