                       boolean blockExternal)

Method Detail

### parseXMLDocument

    public TreeNode parseXMLDocument(java.lang.String location,
                                     org.xml.sax.InputSource is)
                              throws JasperException

  Parse the specified XML document, and return a `TreeNode` that corresponds to the root node of the document tree.

  Parameters:
    `location` - Location (eg URI) of the XML document being parsed
    `is` - Input source containing the deployment descriptor
  Throws:
    `JasperException` - if an input/output error occurs
    `JasperException` - if a parsing error occurs

### parseXMLDocument

    public TreeNode parseXMLDocument(java.lang.String uri,
                                     java.io.InputStream is)
                              throws JasperException

  Parse the specified XML document, and return a `TreeNode` that corresponds to the root node of the document tree.

  Parameters:
    `uri` - URI of the XML document being parsed
    `is` - Input stream containing the deployment descriptor
  Throws:
    `JasperException` - if an input/output error occurs
    `JasperException` - if a parsing error occurs

### setEntityResolver

    public static void setEntityResolver(org.xml.sax.EntityResolver er)

  Set the EntityResolver. This is needed when the dtds and Jasper itself are in different classloaders (e.g. OSGi environment).

  Parameters:
    `er` - EntityResolver to use.

### convert

    protected TreeNode convert(TreeNode parent,
                               org.w3c.dom.Node node)

  Create and return a TreeNode that corresponds to the specified Node, including processing all of the attributes and children nodes.

  Parameters:
    `parent` - The parent TreeNode (if any) for the new TreeNode
    `node` - The XML document Node to be converted
