Method Summary

ElemTemplateElement
appendChild(ElemTemplateElement newChild)
Add a child to the child list.
void

execute(TransformerImpl transformer)
Execute the string expression and copy the text to the result tree.
boolean
getDisableOutputEscaping()
Get the "disable-output-escaping" attribute.
String
getNodeName()
Return the node name.
XPath
getSelect()
Get the "select" attribute.
int
getXSLToken()
Get an integer representation of the element type.
void
setDisableOutputEscaping(boolean v)
Set the "disable-output-escaping" attribute.
void
setSelect(XPath v)

Method Details

appendChild

public ElemTemplateElement appendChild(ElemTemplateElement newChild)
Add a child to the child list.
Overrides:
appendChild in interface ElemTemplateElement

Parameters:
newChild - Child to add to children list

Returns:
Child just added to children list


compose

public void compose(StylesheetRoot sroot)
            throws TransformerException
This function is called after everything else has been recomposed, and allows the template to set remaining values that may be based on some other property that depends on recomposition. NEEDSDOC @param sroot
Overrides:
compose in interface ElemTemplateElement

Throws:
TransformerException -


execute

public void execute(TransformerImpl transformer)
            throws TransformerException
Execute the string expression and copy the text to the result tree. The required select attribute is an expression; this expression is evaluated and the resulting object is converted to a string as if by a call to the string function. The string specifies the string-value of the created text node. If the string is empty, no text node will be created. The created text node will be merged with any adjacent text nodes.
Overrides:
execute in interface ElemTemplateElement

Parameters:
transformer - non-null reference to the the current transform-time state.

Throws:
TransformerException -

getDisableOutputEscaping

public boolean getDisableOutputEscaping()
Get the "disable-output-escaping" attribute. Normally, the xml output method escapes & and <32(and possibly other characters) when outputting text nodes. This ensures that the output is well-formed XML. However, it is sometimes convenient to be able to produce output that is almost, but not quite well-formed XML; for example, the output may include ill-formed sections which are intended to be transformed into well-formed XML by a subsequent non-XML aware process. For this reason, XSLT provides a mechanism for disabling output escaping. An xsl:value-of or xsl:text element may have a disable-output-escaping attribute; the allowed values are yes or no; the default is no; if the value is yes, then a text node generated by instantiating the xsl:value-of or xsl:text element should be output without any escaping.

Returns:
The value of the "disable-output-escaping" attribute.

See Also:
disable-output-escaping in XSLT Specification


getNodeName

public String getNodeName()
Return the node name.
Specified by:
getNodeName in interface Node
Overrides:
getNodeName in interface ElemTemplateElement

Returns:
The node name


getSelect

public XPath getSelect()
Get the "select" attribute. The required select attribute is an expression; this expression is evaluated and the resulting object is converted to a string as if by a call to the string function.

Returns:
The value of the "select" attribute.


getXSLToken

public int getXSLToken()
Get an integer representation of the element type.
Overrides:
getXSLToken in interface ElemTemplateElement

Returns:
An integer representation of the element, defined in the Constants class.

setDisableOutputEscaping

public void setDisableOutputEscaping(boolean v)
Set the "disable-output-escaping" attribute. Normally, the xml output method escapes & and <32(and possibly other characters) when outputting text nodes. This ensures that the output is well-formed XML. However, it is sometimes convenient to be able to produce output that is almost, but not quite well-formed XML; for example, the output may include ill-formed sections which are intended to be transformed into well-formed XML by a subsequent non-XML aware process. For this reason, XSLT provides a mechanism for disabling output escaping. An xsl:value-of or xsl:text element may have a disable-output-escaping attribute; the allowed values are yes or no; the default is no; if the value is yes, then a text node generated by instantiating the xsl:value-of or xsl:text element should be output without any escaping.

Parameters:
v - The value to set for the "disable-output-escaping" attribute.

See Also:
disable-output-escaping in XSLT Specification


setSelect

public void setSelect(XPath v)
Set the "select" attribute. The required select attribute is an expression; this expression is evaluated and the resulting object is converted to a string as if by a call to the string function.

Parameters:
v - The value to set for the "select" attribute.
