## Detailed Description

The QXmlAttributes class provides XML attributes.

If attributes are reported by QXmlContentHandler.startElement() this class is used to pass the attribute values.

Use index() to locate the position of an attribute in the list, count() to retrieve the number of attributes, and clear() to remove the attributes. New attributes can be added with append(). Use type() to get an attribute's type and value() to get its value. The attribute's name is available from localName() or qName(), and its namespace URI from uri().

## Method Documentation

### QXmlAttributes.__init__ (self)

Constructs an empty attribute list.

### QXmlAttributes.__init__ (self, QXmlAttributes)

### QXmlAttributes.append (self, QString, QString, QString, QString)

Appends a new attribute entry to the list of attributes. The qualified name of the attribute is qName, the namespace URI is uri and the local name is localPart. The value of the attribute is value.

See also qName(), uri(), localName(), and value().

### QXmlAttributes.clear (self)

Clears the list of attributes.

See also append().

### int QXmlAttributes.count (self)

Returns the number of attributes in the list. This function is equivalent to length().

### int QXmlAttributes.index (self, QString)

Looks up the index of an attribute by the qualified name qName.

Returns the index of the attribute or -1 if it wasn't found.

See also Namespace Support via Features.

### int QXmlAttributes.index (self, QString, QString)

This is an overloaded function.

### int QXmlAttributes.length (self)

Returns the number of attributes in the list.

See also count().

### QString QXmlAttributes.localName (self, int)

Looks up an attribute's local name for the attribute at position index. If no namespace processing is done, the local name is an empty string.

See also Namespace Support via Features.

### QString QXmlAttributes.qName (self, int)

Looks up an attribute's XML 1.0 qualified name for the attribute at position index.

See also Namespace Support via Features.

### QString QXmlAttributes.type (self, int)

Looks up an attribute's type for the attribute at position index.

Currently only "CDATA" is returned.

### QString QXmlAttributes.type (self, QString)

This is an overloaded function.

Looks up an attribute's type for the qualified name qName.

Currently only "CDATA" is returned.

### QString QXmlAttributes.type (self, QString, QString)

This is an overloaded function.

Looks up an attribute's type by namespace name.

uri specifies the namespace URI and localName specifies the local name. If the name has no namespace URI, use an empty string for uri.

Currently only "CDATA" is returned.

### QString QXmlAttributes.uri (self, int)

Looks up an attribute's namespace URI for the attribute at position index. If no namespace processing is done or if the attribute has no namespace, the namespace URI is an empty string.

See also Namespace Support via Features.

### QString QXmlAttributes.value (self, int)

Returns an attribute's value for the attribute at position index. The index must be a valid position (i.e., 0 <= index < count()).

### QString QXmlAttributes.value (self, QString)

This is an overloaded function.

Returns an attribute's value for the qualified name qName, or an empty string if no attribute exists for the name given.

See also Namespace Support via Features.

### QString QXmlAttributes.value (self, QString, QString)

This is an overloaded function.

Returns an attribute's value for the qualified name qName, or an empty string if no attribute exists for the name given.

See also Namespace Support via Features.
