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。
| 参数： | arg__1 – PySide.QtXml.QDomNodeList |
|---|
Creates an empty node list.
构造副本为 n .
| 参数： | index – PySide.QtCore.int |
|---|---|
| 返回类型： | PySide.QtXml.QDomNode |
提供此函数是为 Qt API 一致性。它相当于 PySide.QtXml.QDomNodeList.item() .
若 index 为负或者若 index >= PySide.QtXml.QDomNodeList.length() then a null node is returned (i.e. a node for which QDomNode.isNull() returns true).
| 返回类型： | PySide.QtCore.int |
|---|
提供此函数是为 Qt API 一致性。它相当于 PySide.QtXml.QDomNodeList.length() .
| 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.
| 参数： | index – PySide.QtCore.int |
|---|---|
| 返回类型： | PySide.QtXml.QDomNode |
返回节点在位置 index .
若 index 为负或者若 index >= PySide.QtXml.QDomNodeList.length() then a null node is returned (i.e. a node for which QDomNode.isNull() returns true).
| 返回类型： | PySide.QtCore.uint |
|---|
返回列表节点数。
| 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.
| 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.
| 返回类型： | PySide.QtCore.int |
