Method Details

isUrlAttribute

public boolean isUrlAttribute(int element,
 int attribute)

startDocument

public void startDocument(int properties)
                   throws XPathException

Start of a document node.

Specified by:

startDocument in interface Receiver

Overrides:

startDocument in class ProxyReceiver

Throws:

XPathException

startElement

public void startElement(int nameCode,
 int typeCode,
 int locationId,
 int properties)
                  throws XPathException

Notify the start of an element

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

Parameters:

nameCode - integer code identifying the name of the element within the name pool.

typeCode - integer code identifying the element's type within the name pool.

locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.

properties - properties of the element node

Throws:

XPathException

attribute

public void attribute(int nameCode,
 int typeCode,
 CharSequence value,
 int locationId,
 int properties)
               throws XPathException

Notify an attribute. Attributes are notified after the startElement event, and before any children. Namespaces and attributes may be intermingled.

Specified by:

attribute in interface Receiver

Overrides:

attribute in class ProxyReceiver

Parameters:

nameCode - The name of the attribute, as held in the name pool

typeCode - The type of the attribute, as held in the name pool

locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.

properties - Bit significant value. The following bits are defined:

DISABLE_ESCAPING

Disable escaping for this attribute

NO_SPECIAL_CHARACTERS

Attribute value contains no special characters

Throws:

XPathException

escapeURL

public static CharSequence escapeURL(CharSequence url,
 boolean normalize)

Escape a URI according to the HTML rules: that is, a non-ASCII character (specifically, a character outside the range 32 - 126) is replaced by the %HH encoding of the octets in its UTF-8 representation

Parameters:
