• NSStack

  public NSStack()

Method Detail

• push

  public void push()

• pop

  public void pop()

  Leave a scope: this removes any NS declarations that were added in the last scope. Note that I don't bother to validate that you don't call popScope too many times; that's your problem.

• add

  public void add(String prefix,
         String uri)

  Add a new declaration to the current scope. This is visible within the current scope as well as from any nested scopes.

  Parameters:

  prefix - the prefix to be used for this namespace

  uri - the namespace name of this namespace.

• add

  public String add(String uri)

  Add a new declaration to the current scope using a unique prefix and return the prefix. This is useful when one just wants to add a decl and doesn't want to have to deal with creating unique prefixes. If the namespace name is already declared and in scope, then the previously declared prefix is returned.

  Parameters:

  uri - the namespace name of this namespace

  Returns:

  the unique prefix created or previously declared for this namespace

• getPrefix

  public String getPrefix(String uri)

  Return the prefix associated with the given namespace name by looking thru all the namespace declarations that are in scope.

  Parameters:

  uri - the namespace name for whom a declared prefix is desired

  Returns:

  the prefix or null if namespace name not found

• getURI

  public String getURI(String prefix)

  Return the namespace name associated with the given prefix by looking thru all the namespace declarations that are in scope.

  Parameters:

  prefix - the prefix for whom a declared namespace name is desired

  Returns:

  the namespace name or null if prefix not found
