Mandatory Escape Sequences | Cisco Systems OL-20949-01 guide

Chapter 3 CiscoIPPhone XML Objects

XML Considerations

Note All CiscoIPPhone element names and attribute names are case sensitive.

Mandatory Escape Sequences

By XML convention, the XML parser also requires that you provide escape values for a few special characters. Table 3-5lists characters and their escape values.

.

Table 3-5	Escape Sequences for Special Characters

Character	Name	Escape Sequence

&	Ampersand	&

“	Quote	"

'	Apostrophe	'

<	Left angle bracket	<

>	Right angle bracket	>

Escaping text can be tedious, but some authoring tools or scripting languages can automate this task.

XML Encoding

Because the phone firmware can support multiple encodings, the XML encoding should always be set in the XML header.

If the XML encoding header is not specified, the phone will default to the encoding specified by the current user locale.

Note This behavior is NOT compliant with XML standards, which specify UTF-8 as the default encoding, so any UTF-8 encoded XML object must have the encoding explicitly set for the phone to parse it correctly.

The encoding value specified in the XML header must match one of the encodings provided by the IP Phone in its Accept-Charset HTTP request header, as shown in the example below.

Example

The following examples illustrate UTF-8 and ISO-8859-1 encoding, respectively:

<?xml version="1.0" encoding="utf-8" ?>

<?xml version="1.0" encoding="iso-8859-1" ?>

For details on setting HTTP header encoding settings, see the “HTTP Encoding Header Setting” section on page 6-6.
