    • setSelect

      public void setSelect(XPath v)
      Set the "select" attribute. xsl:sort has a select attribute whose value is an expression. For each node to be processed, the expression is evaluated with that node as the current node and with the complete list of nodes being processed in unsorted order as the current node list. The resulting object is converted to a string as if by a call to the string function; this string is used as the sort key for that node. The default value of the select attribute is ., which will cause the string-value of the current node to be used as the sort key.
      Parameters:
      v - Value to set for the "select" attribute
    • getSelect

      public XPath getSelect()
      Get the "select" attribute. xsl:sort has a select attribute whose value is an expression. For each node to be processed, the expression is evaluated with that node as the current node and with the complete list of nodes being processed in unsorted order as the current node list. The resulting object is converted to a string as if by a call to the string function; this string is used as the sort key for that node. The default value of the select attribute is ., which will cause the string-value of the current node to be used as the sort key.
      Returns:
      The value of the "select" attribute
    • setLang

      public void setLang(AVT v)
      Set the "lang" attribute. lang specifies the language of the sort keys; it has the same range of values as xml:lang [XML]; if no lang value is specified, the language should be determined from the system environment.
      Parameters:
      v - The value to set for the "lang" attribute
    • getLang

      public AVT getLang()
      Get the "lang" attribute. lang specifies the language of the sort keys; it has the same range of values as xml:lang [XML]; if no lang value is specified, the language should be determined from the system environment.
      Returns:
      The value of the "lang" attribute
    • setDataType

      public void setDataType(AVT v)
      Set the "data-type" attribute. data-type specifies the data type of the strings; the following values are allowed:
      • text specifies that the sort keys should be sorted lexicographically in the culturally correct manner for the language specified by lang.
      • number specifies that the sort keys should be converted to numbers and then sorted according to the numeric value; the sort key is converted to a number as if by a call to the number function; the lang attribute is ignored.
      • A QName with a prefix is expanded into an expanded-name as described in [2.4 Qualified Names]; the expanded-name identifies the data-type; the behavior in this case is not specified by this document.

      The default value is text.

      NOTE: The XSL Working Group plans that future versions of XSLT will leverage XML Schemas to define further values for this attribute.
      Parameters:
      v - Value to set for the "data-type" attribute
    • getDataType

      public AVT getDataType()
      Get the "data-type" attribute. data-type specifies the data type of the strings; the following values are allowed:
      • text specifies that the sort keys should be sorted lexicographically in the culturally correct manner for the language specified by lang.
      • number specifies that the sort keys should be converted to numbers and then sorted according to the numeric value; the sort key is converted to a number as if by a call to the number function; the lang attribute is ignored.
      • A QName with a prefix is expanded into an expanded-name as described in [2.4 Qualified Names]; the expanded-name identifies the data-type; the behavior in this case is not specified by this document.

      The default value is text.

      NOTE: The XSL Working Group plans that future versions of XSLT will leverage XML Schemas to define further values for this attribute.
      Returns:
      The value of the "data-type" attribute
    • setOrder

      public void setOrder(AVT v)
      Set the "order" attribute. order specifies whether the strings should be sorted in ascending or descending order; ascending specifies ascending order; descending specifies descending order; the default is ascending.
      Parameters:
      v - The value to set for the "order" attribute
    • getOrder

      public AVT getOrder()
      Get the "order" attribute. order specifies whether the strings should be sorted in ascending or descending order; ascending specifies ascending order; descending specifies descending order; the default is ascending.
      Returns:
      The value of the "order" attribute
    • setCaseOrder

      public void setCaseOrder(AVT v)
      Set the "case-order" attribute. case-order has the value upper-first or lower-first; this applies when data-type="text", and specifies that upper-case letters should sort before lower-case letters or vice-versa respectively. For example, if lang="en", then A a B b are sorted with case-order="upper-first" and a A b B are sorted with case-order="lower-first". The default value is language dependent.
      Parameters:
      v - The value to set for the "case-order" attribute
    • getCaseOrder

      public AVT getCaseOrder()
      Get the "case-order" attribute. case-order has the value upper-first or lower-first; this applies when data-type="text", and specifies that upper-case letters should sort before lower-case letters or vice-versa respectively. For example, if lang="en", then A a B b are sorted with case-order="upper-first" and a A b B are sorted with case-order="lower-first". The default value is language dependent.
      Returns:
      The value of the "case-order" attribute
    • getXSLToken

      public int getXSLToken()
      Get an int constant identifying the type of element.
      Overrides:
      getXSLToken in class ElemTemplateElement
      Returns:
      The token ID of the element

      public String getNodeName()
      Return the node name.
      Specified by:
      getNodeName in interface Node
      Overrides:
      getNodeName in class ElemTemplateElement
      Returns:
      The element's name
    • appendChild

      public Node appendChild(Node newChild) throws DOMException
      Add a child to the child list.

      Throws:
      DOMException
    • 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.
      Overrides:
      compose in class ElemTemplateElement
      Throws:
      TransformerException
