XSLT 2.0 and XPath 2.0 Programmer's Reference, 4th Edition (217 page)

The following example might be used if the output of the stylesheet is a comma-separated-values file using US ASCII characters only:

xsl:output-character

The

element allows a character in the result tree to be mapped to a specific string used to represent this character in the serialized output.

Changes in 2.0

The element is new in XSLT 2.0.

Format

Position

only appears as a child of the

element.

Attributes

Content

None. The

element is always empty.

Effect

The

element defines a mapping for a single character within a character map. The way character maps work is described in the entry for the

element on page 280, and in Chapter 15.

The character to be replaced, and the string that is to replace it, must consist entirely of valid XML characters; otherwise, it would not be possible to represent them in the stylesheet. Any special characters must be escaped in the usual way. For example, if you want the ampersand character to be mapped to the string
&ersand;
, write:

xsl:param

The

element is used either at the top level, to describe a global parameter, or immediately within an

or

element, to describe a local parameter to a template or function. It specifies a name for the parameter and a default value, which is used if the caller supplies no value for the parameter.

Changes in 2.0

An
as
attribute has been added to define the required type of the parameter.

A
required
attribute has been added to indicate whether the parameter is mandatory or optional.

A
tunnel
attribute has been added to support the new facility of tunnel parameters.

Format

Different subsets of the format are applicable to stylesheet parameters, template parameters, and function parameters.

Format for Stylesheet Parameters

Format for Template Parameters

Format for Function Parameters

Position

may appear as a top-level declaration (a child of the

element), or as an immediate child element of

or

. The three kinds of parameters are known as
stylesheet parameters
,
template parameters
, and
function parameters
. In the case of template parameters and function parameters,

elements must come before any other child elements.

Attributes

Name	Value	Meaning
name mandatory	Lexical QName	The name of the parameter
select optional	XPath Expression	The default value of the parameter if no explicit value is supplied by the caller
as optional	Sequence Type	The required type of the parameter value
required optional	yes or no	Indicates whether the parameter is optional or mandatory
tunnel optional	yes or no	Indicates whether the parameter is a tunnel parameter
