public interface XMLStreamReader
extends XMLStreamConstants

The XMLStreamReader interface allows forward, read-only access to XML. It is designed to be the lowest level and most efficient way to read XML data.

The XMLStreamReader is designed to iterate over XML using next() and hasNext(). The data can be accessed using methods such as getEventType(), getNamespaceURI(), getLocalName() and getText();

The next() method causes the reader to read the next parse event. The next() method returns an integer which identifies the type of event just read.

The event type can be determined using getEventType().

Parsing events are defined as the XML Declaration, a DTD, start tag, character data, white space, end tag, comment, or processing instruction. An attribute or namespace event may be encountered at the root level of a document as the result of a query operation.

For XML 1.0 compliance an XML processor must pass the identifiers of declared unparsed entities, notation declarations and their associated identifiers to the application. This information is provided through the property API on this interface. The following two properties allow access to this information: javax.xml.stream.notations and javax.xml.stream.entities. When the current event is a DTD the following call will return a list of Notations List l = (List) getProperty("javax.xml.stream.notations"); The following call will return a list of entity declarations: List l = (List) getProperty("javax.xml.stream.entities"); These properties can only be accessed during a DTD event and are defined to return null if the information is not available.

The following table describes which methods are valid in what state. If a method is called in an invalid state the method will throw a java.lang.IllegalStateException.

- Method Detail
  - getProperty
```
Object getProperty(String name)
                   throws IllegalArgumentException
```
    Get the value of a feature/property from the underlying implementation
    
    Parameters:
    name - The name of the property, may not be null
    
    Returns:
    The value of the property
    
    Throws:
    
    IllegalArgumentException - if name is null
  - next
```
int next()
         throws XMLStreamException
```
    Get next parsing event - a processor may return all contiguous character data in a single chunk, or it may split it into several chunks. If the property javax.xml.stream.isCoalescing is set to true element content must be coalesced and only one CHARACTERS event must be returned for contiguous element content or CDATA Sections. By default entity references must be expanded and reported transparently to the application. An exception will be thrown if an entity reference cannot be expanded. If element content is empty (i.e. content is "") then no CHARACTERS event will be reported.
    Given the following XML:
    <foo>content text<![CDATA[<greeting>Hello</greeting>]]>other content</foo>
    The behavior of calling next() when being on foo will be:
    1- the comment (COMMENT)
    2- then the characters section (CHARACTERS)
    3- then the CDATA section (another CHARACTERS)
    4- then the next characters section (another CHARACTERS)
    5- then the END_ELEMENT
    
    NOTE: empty element (such as <tag/>) will be reported with two separate events: START_ELEMENT, END_ELEMENT - This preserves parsing equivalency of empty element to <tag></tag>. This method will throw an IllegalStateException if it is called after hasNext() returns false.
    
    Returns:
    the integer code corresponding to the current parse event
    
    Throws:
    
    NoSuchElementException - if this is called when hasNext() returns false
    
    XMLStreamException - if there is an error processing the underlying XML source

  - require
```
void require(int type,
           String namespaceURI,
           String localName)
             throws XMLStreamException
```
    Test if the current event is of the given type and if the namespace and name match the current namespace and name of the current event. If the namespaceURI is null it is not checked for equality, if the localName is null it is not checked for equality.
    
    Parameters:
    type - the event type
    namespaceURI - the uri of the event, may be null
    localName - the localName of the event, may be null
    
    Throws:
    
    XMLStreamException - if the required values are not matched.
  - getElementText
```
String getElementText()
                      throws XMLStreamException
```
    Reads the content of a text-only element, an exception is thrown if this is not a text-only element. Regardless of value of javax.xml.stream.isCoalescing this method always returns coalesced content.
    Precondition: the current event is START_ELEMENT.
    Postcondition: the current event is the corresponding END_ELEMENT.
    The method does the following (implementations are free to optimized but must do equivalent processing):
```
 if(getEventType() != XMLStreamConstants.START_ELEMENT) {
 throw new XMLStreamException(
 "parser must be on START_ELEMENT to read next text", getLocation());
 }
 int eventType = next();
 StringBuffer content = new StringBuffer();
 while(eventType != XMLStreamConstants.END_ELEMENT ) {
 if(eventType == XMLStreamConstants.CHARACTERS
 || eventType == XMLStreamConstants.CDATA
 || eventType == XMLStreamConstants.SPACE
 || eventType == XMLStreamConstants.ENTITY_REFERENCE) {
 buf.append(getText());
 } else if(eventType == XMLStreamConstants.PROCESSING_INSTRUCTION
 || eventType == XMLStreamConstants.COMMENT) {
 // skipping
 } else if(eventType == XMLStreamConstants.END_DOCUMENT) {
 throw new XMLStreamException(
 "unexpected end of document when reading element text content", this);
 } else if(eventType == XMLStreamConstants.START_ELEMENT) {
 throw new XMLStreamException(
 "element text content may not contain START_ELEMENT", getLocation());
 } else {
 throw new XMLStreamException(
 "Unexpected event type "+eventType, getLocation());
 }
 eventType = next();
 }
 return buf.toString();
 
```
    Throws:
    
    XMLStreamException - if the current event is not a START_ELEMENT or if a non text element is encountered
  - nextTag
```
int nextTag()
            throws XMLStreamException
```
    Skips any white space (isWhiteSpace() returns true), COMMENT, or PROCESSING_INSTRUCTION, until a START_ELEMENT or END_ELEMENT is reached. If other than white space characters, COMMENT, PROCESSING_INSTRUCTION, START_ELEMENT, END_ELEMENT are encountered, an exception is thrown. This method should be used when processing element-only content seperated by white space.
    Precondition: none
    Postcondition: the current event is START_ELEMENT or END_ELEMENT and cursor may have moved over any whitespace event.
    Essentially it does the following (implementations are free to optimized but must do equivalent processing):
```
 int eventType = next();
 while((eventType == XMLStreamConstants.CHARACTERS && isWhiteSpace()) // skip whitespace
 || (eventType == XMLStreamConstants.CDATA && isWhiteSpace())
 // skip whitespace
 || eventType == XMLStreamConstants.SPACE
 || eventType == XMLStreamConstants.PROCESSING_INSTRUCTION
 || eventType == XMLStreamConstants.COMMENT
 ) {
 eventType = next();
 }
 if (eventType != XMLStreamConstants.START_ELEMENT && eventType != XMLStreamConstants.END_ELEMENT) {
 throw new String XMLStreamException("expected start or end tag", getLocation());
 }
 return eventType;
 
```
    Returns:
    the event type of the element read (START_ELEMENT or END_ELEMENT)
    
    Throws:
    
    XMLStreamException - if the current event is not white space, PROCESSING_INSTRUCTION, START_ELEMENT or END_ELEMENT
    
    NoSuchElementException - if this is called when hasNext() returns false
  - hasNext
```
boolean hasNext()
                throws XMLStreamException
```
    Returns true if there are more parsing events and false if there are no more events. This method will return false if the current state of the XMLStreamReader is END_DOCUMENT
    
    Returns:
    true if there are more events, false otherwise
    
    Throws:
    
    XMLStreamException - if there is a fatal error detecting the next state
  - close
```
void close()
           throws XMLStreamException
```
    Frees any resources associated with this Reader. This method does not close the underlying input source.
    
    Throws:
    
    XMLStreamException - if there are errors freeing associated resources
  - getNamespaceURI
```
String getNamespaceURI(String prefix)

```
    Gets the the text associated with a CHARACTERS, SPACE or CDATA event. Text starting a "sourceStart" is copied into "target" starting at "targetStart". Up to "length" characters are copied. The number of characters actually copied is returned. The "sourceStart" argument must be greater or equal to 0 and less than or equal to the number of characters associated with the event. Usually, one requests text starting at a "sourceStart" of 0. If the number of characters actually copied is less than the "length", then there is no more text. Otherwise, subsequent calls need to be made until all text has been retrieved. For example: int length = 1024; char[] myBuffer = new char[ length ]; for ( int sourceStart = 0 ; ; sourceStart += length ) { int nCopied = stream.getTextCharacters( sourceStart, myBuffer, 0, length ); if (nCopied < length) break; } XMLStreamException may be thrown if there are any XML errors in the underlying source.
