    详细描述

    PySide.QtXml.QXmlAttributes class provides XML attributes.

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

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

    class PySide.QtXml. QXmlAttributes
    class PySide.QtXml. QXmlAttributes ( QXmlAttributes )
    参数: QXmlAttributes PySide.QtXml.QXmlAttributes

    Constructs an empty attribute list.

    PySide.QtXml.QXmlAttributes. append ( qName , uri , localPart , value )
    参数:
    • qName – unicode
    • uri – unicode
    • localPart – unicode
    • value – unicode

    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 .

    PySide.QtXml.QXmlAttributes. clear ( )

    Clears the list of attributes.

    PySide.QtXml.QXmlAttributes. count ( )
    返回类型: PySide.QtCore.int

    Returns the number of attributes in the list. 此函数相当于 PySide.QtXml.QXmlAttributes.length() .

    PySide.QtXml.QXmlAttributes. index ( qName )
    参数: qName – unicode
    返回类型: PySide.QtCore.int

    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.

    PySide.QtXml.QXmlAttributes. index ( uri , localPart )
    参数:
    • uri – unicode
    • localPart – unicode
    返回类型:

    PySide.QtCore.int

    这是重载函数。

    Looks up the index of an attribute by a namespace name.

    uri specifies the namespace URI, or an empty string if the name has no namespace URI. localPart specifies the attribute's local name.

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

    PySide.QtXml.QXmlAttributes. length ( )
    返回类型: PySide.QtCore.int

    Returns the number of attributes in the list.

    PySide.QtXml.QXmlAttributes. localName ( index )
    参数: index PySide.QtCore.int
    返回类型: unicode

    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.

    PySide.QtXml.QXmlAttributes. type ( index )
    参数: index PySide.QtCore.int
    返回类型: unicode

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

    Currently only “CDATA” is returned.

    PySide.QtXml.QXmlAttributes. type ( uri , localName )
    参数:
    • uri – unicode
    • localName – unicode
    返回类型:

    unicode

    这是重载函数。

    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.

    PySide.QtXml.QXmlAttributes. type ( qName )
    参数: qName – unicode
    返回类型: unicode

    这是重载函数。

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

    Currently only “CDATA” is returned.

    PySide.QtXml.QXmlAttributes. uri ( index )
    参数: index PySide.QtCore.int
    返回类型: unicode

    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.
