    详细描述

    PySide.QtXml.QDomNodeList class is a list of PySide.QtXml.QDomNode 对象。

    Lists can be obtained by QDomDocument.elementsByTagName() and QDomNode.childNodes() . The Document Object Model (DOM) requires these lists to be “live”: whenever you change the underlying document, the contents of the list will get updated.

    You can get a particular node from the list with PySide.QtXml.QDomNodeList.item() . The number of items in the list is returned by PySide.QtXml.QDomNodeList.length() .

    For further information about the Document Object Model see Level 1 and Level 2 Core. For a more general introduction of the DOM implementation see the PySide.QtXml.QDomDocument 文档编制。

    class PySide.QtXml. QDomNodeList
    class PySide.QtXml. QDomNodeList ( arg__1 )
    参数: arg__1 PySide.QtXml.QDomNodeList

    Creates an empty node list.

    构造副本为 n .

    PySide.QtXml.QDomNodeList. at ( index )
    参数: index PySide.QtCore.int
    返回类型: PySide.QtXml.QDomNode

    This function is provided for Qt API consistency. It is equivalent to PySide.QtXml.QDomNodeList.item() .

    index is negative or if index >= PySide.QtXml.QDomNodeList.length() then a null node is returned (i.e. a node for which QDomNode.isNull() returns true).

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

    This function is provided for Qt API consistency. It is equivalent to PySide.QtXml.QDomNodeList.length() .

    PySide.QtXml.QDomNodeList. isEmpty ( )
    返回类型: PySide.QtCore.bool

    Returns true if the list contains no items; otherwise returns false. This function is provided for Qt API consistency.

    PySide.QtXml.QDomNodeList. item ( index )
    参数: index PySide.QtCore.int
    返回类型: PySide.QtXml.QDomNode

    Returns the node at position index .

    index is negative or if index >= PySide.QtXml.QDomNodeList.length() then a null node is returned (i.e. a node for which QDomNode.isNull() returns true).

    PySide.QtXml.QDomNodeList. length ( )
    返回类型: PySide.QtCore.uint

    Returns the number of nodes in the list.

    PySide.QtXml.QDomNodeList. __ne__ ( arg__1 )
    参数: arg__1 PySide.QtXml.QDomNodeList
    返回类型: PySide.QtCore.bool

    Returns true the node list n and this node list are not equal; otherwise returns false.

    PySide.QtXml.QDomNodeList. __eq__ ( arg__1 )
    参数: arg__1 PySide.QtXml.QDomNodeList
    返回类型: PySide.QtCore.bool

    Returns true if the node list n and this node list are equal; otherwise returns false.

    PySide.QtXml.QDomNodeList. size ( )
    返回类型: PySide.QtCore.int

    This function is provided for Qt API consistency. It is equivalent to PySide.QtXml.QDomNodeList.length() .
