Constructor Detail

ElemValueOf

public ElemValueOf()
Method Detail

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.

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.

setDisableOutputEscaping

public void setDisableOutputEscaping(boolean v)
Set the "disable-output-escaping" attribute. Normally, the xml output method escapes & and < (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

getDisableOutputEscaping

public boolean getDisableOutputEscaping()
Get the "disable-output-escaping" attribute. Normally, the xml output method escapes & and < (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

getXSLToken

public int getXSLToken()
Get an integer representation of the element type.
Returns:
An integer representation of the element, defined in the Constants class.
Overrides:
getXSLToken in class ElemTemplateElement
See Also:
Constants

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
Throws:
TransformerException -  
Overrides:
compose in class ElemTemplateElement

getNodeName

public java.lang.String getNodeName()
Return the node name.
Returns:
The node name
Overrides:
getNodeName in class ElemTemplateElement

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.
Parameters:
transformer - non-null reference to the the current transform-time state.
Throws:
TransformerException -  
Overrides:
execute in class ElemTemplateElement
See Also:
value-of in XSLT Specification

appendChild

public ElemTemplateElement appendChild(ElemTemplateElement newChild)
Add a child to the child list.
Parameters:
newChild - Child to add to children list
Returns:
Child just added to children list
Throws:
DOMException -  
Overrides:
appendChild in class ElemTemplateElement
