    - #### 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.

        disable-output-escaping in XSLT Specification

    - #### getXSLToken

          public int getXSLToken()

      Get an integer representation of the element type.
      Overrides:
        `getXSLToken` in class `ElemTemplateElement`
      Returns:
        An integer representation of the element, defined in the Constants class.
      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
      Overrides:
        `compose` in class `ElemTemplateElement`
      Throws:
        `TransformerException`

    - #### getNodeName

          public java.lang.String getNodeName()

      Return the node name.
      Specified by:
        `getNodeName` in interface `Node`
      Overrides:
        `getNodeName` in class `ElemTemplateElement`
      Returns:
        The node name

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

    - #### appendChild

          public ElemTemplateElement appendChild(ElemTemplateElement newChild)

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