## org.apache.xalan.templates
Class XSLTVisitor

    java.lang.Object
      org.apache.xpath.XPathVisitor
          org.apache.xalan.templates.XSLTVisitor

Direct Known Subclasses:
  RedundentExprEliminator

    public class XSLTVisitor

extends XPathVisitor

A derivation from this class can be passed to a class that implements the XSLTVisitable interface, to have the appropriate method called for each component of an XSLT stylesheet. Aside from possible other uses, the main intention is to provide a reasonable means to perform expression rewriting.

Constructor Detail

### XSLTVisitor

    public XSLTVisitor()

Method Detail

### visitInstruction

    public boolean visitInstruction(ElemTemplateElement elem)

  Visit an XSLT instruction. Any element that isn't called by one of the other visit methods, will be called by this method.

  Parameters:
    `elem` - The xsl instruction element object.
  Returns:
    true if the sub expressions should be traversed.

### visitStylesheet

    public boolean visitStylesheet(ElemTemplateElement elem)

  Visit an XSLT stylesheet instruction.

  Parameters:
    `elem` - The xsl instruction element object.
  Returns:
    true if the sub expressions should be traversed.

### visitTopLevelInstruction

    public boolean visitTopLevelInstruction(ElemTemplateElement elem)

  Visit an XSLT top-level instruction.

  Parameters:
    `elem` - The xsl instruction element object.
  Returns:
    true if the sub expressions should be traversed.

### visitTopLevelVariableOrParamDecl

    public boolean visitTopLevelVariableOrParamDecl(ElemTemplateElement elem)

  Visit an XSLT top-level instruction.

  Parameters:
    `elem` - The xsl instruction element object.
  Returns:
    true if the sub expressions should be traversed.

### visitVariableOrParamDecl

    public boolean visitVariableOrParamDecl(ElemVariable elem)

  Visit an XSLT variable or parameter declaration.

  Parameters:
    `elem` - The xsl instruction element object.
  Returns:
    true if the sub expressions should be traversed.

### visitLiteralResultElement

    public boolean visitLiteralResultElement(ElemLiteralResult elem)

  Visit a LiteralResultElement.

  Parameters:
    `elem` - The literal result object.
  Returns:
    true if the sub expressions should be traversed.

### visitAVT

    public boolean visitAVT(AVT elem)

  Visit an Attribute Value Template (at the top level).

  Parameters:
    `elem` - The attribute value template object.
  Returns:
    true if the sub expressions should be traversed.

### visitExtensionElement

    public boolean visitExtensionElement(ElemExtensionCall elem)

  Visit an extension element.

  Parameters:
    `elem` - The extension object.
  Returns:
    true if the sub expressions should be traversed.
