Method Detail

printRaw

void printRaw(java.lang.String s)
              throws java.io.IOException

Send raw data to the stream. Mainly useful for things like DOCTYPE declarations. Use with care!

Parameters:

s - a string of data to include verbatim in the XML stream

Throws:

java.io.IOException

openTag

void openTag(java.lang.String nsURI,
           java.lang.String localName)
             throws java.io.IOException

Open a new namespace-qualified XML tag.

Parameters:

nsURI - A URI for the namespace to use

localName - The name of the tag

Throws:

java.io.IOException

openTag

void openTag(java.lang.String name)
             throws java.io.IOException

Open a new unqualified XML tag. This may also be used if you want to do namespace management yourself, independantly of the XMLWriter

Parameters:

name - The name of the tag.

Throws:

java.io.IOException

attribute

void attribute(java.lang.String nsURI,
             java.lang.String localName,
             java.lang.String value)
               throws java.io.IOException

Add an attribute to an element. This will throw an exception if it's not called immediately after an openTag command.

Parameters:

nsURI - A URI for the namespace to use

localName - The name of the attribute

value - The textual value of the attribute

Throws:

java.io.IOException

attribute

void attribute(java.lang.String qName,
             java.lang.String value)
               throws java.io.IOException

Add an un-qualified attribute to an element. This will throw an exception if it's not called immediately after an openTag command.

Parameters:

qName - The name of the attribute to set

value - The textual value of the attribute

Throws:

java.io.IOException

print

void print(java.lang.String data)
           throws java.io.IOException

Prints some textual content in an element.

Throws:

java.io.IOException

println

void println(java.lang.String data)
             throws java.io.IOException

Prints some textual content, terminated with a newline character.

Throws:

java.io.IOException

closeTag

void closeTag(java.lang.String nsURI,
            java.lang.String qName)
              throws java.io.IOException

Closes an element

Parameters:

nsURI - A URI for the namespace to use

qName - The name of the tag

Throws:

java.io.IOException

closeTag

void closeTag(java.lang.String name)
              throws java.io.IOException

Closes an un-qualified element.

Parameters:

name - The tag name

Throws:

java.io.IOException

declareNamespace

void declareNamespace(java.lang.String nsURI,
                    java.lang.String prefixHint)
                      throws java.io.IOException

Hints that a namespace is going to be used in a sub-tree. Use this method to avoid namespaces that are used only in leaf-nodes of a tree being re-defined every time they are used. The XMLWriter will generally try to use the suggested prefix for this namespace, but there is no guarentee of this. In particular, if the namespace is already in use, the current prefix will still be used. Similarly if the suggested prefix has already been used for another namespace, a new one will be auto-generated.

Parameters:

nsURI - The namespace to declare

prefixHint - A suggested prefix-string for this namespace.

Throws:

java.io.IOException

close

void close()
           throws java.io.IOException

Close this XMLWriter, and it's underlying stream.

Throws:

java.io.IOException
