## Detailed Description
该QDomElement类表示的DOM树中的元素。
元素有一个[tagName](qdomelement.html#tagName)()和与它们相关联的零个或多个属性。变量名可以被改变[setTagName](qdomelement.html#setTagName)( ) 。
元素属性表示为[QDomAttr](qdomattr.html)可以使用查询对象的[attribute](qdomelement.html#attributex)()和[attributeNode](qdomelement.html#attributeNode)()函数。您可以设置的属性与[setAttribute](qdomelement.html#setAttribute)()和[setAttributeNode](qdomelement.html#setAttributeNode)()函数。属性可以用去除[removeAttribute](qdomelement.html#removeAttribute)( ) 。有命名空间的等值这些功能,即[setAttributeNS](qdomelement.html#setAttributeNS)( )[setAttributeNodeNS](qdomelement.html#setAttributeNodeNS)()和[removeAttributeNS](qdomelement.html#removeAttributeNS)( ) 。
如果您要访问的节点使用的文字[text](qdomelement.html#text)( ),例如
```
QDomElement e = //...
//...
[QString](qstring.html) s = e.text()
```
该[text](qdomelement.html#text)( )函数的递归操作要查找的文本(因为不是所有的元素包含文本)。如果你想找到的所有的节点的子节点的所有文字,迭代孩子找[QDomText](qdomtext.html)节点,例如
```
[QString](qstring.html) text;
QDomElement element = doc.documentElement();
for([QDomNode](qdomnode.html) n = element.firstChild(); !n.isNull(); n = n.nextSibling())
{
[QDomText](qdomtext.html) t = n.toText();
if (!t.isNull())
text += t.data();
}
```
需要注意的是,我们试图给每个节点转换为文本节点,并使用[text](qdomelement.html#text)() ,而不是使用[firstChild](qdomnode.html#firstChild)( ) 。[toText](qdomnode.html#toText)( )数据( )或n 。[toText](qdomnode.html#toText)() 。数据()直接在节点上,因为节点可能不是一个文本元素。
你可以得到一个元素的所有那些与一个指定的标记名称的decendents列表[elementsByTagName](qdomelement.html#elementsByTagName)()或[elementsByTagNameNS](qdomelement.html#elementsByTagNameNS)( ) 。
要浏览一个DOM文档使用的元素[firstChildElement](qdomnode.html#firstChildElement)( )[lastChildElement](qdomnode.html#lastChildElement)( )[nextSiblingElement](qdomnode.html#nextSiblingElement)()和[previousSiblingElement](qdomnode.html#previousSiblingElement)( ) 。例如,迭代中被称为“数据库”根元素称为“入口”的所有子元素,你可以使用:
```
[QDomDocument](qdomdocument.html) doc = // ...
QDomElement root = doc.firstChildElement("database");
QDomElement elt = root.firstChildElement("entry");
for (; !elt.isNull(); elt = elt.nextSiblingElement("entry")) {
// ...
}
```

```
QDomElement.__init__ (self, QDomElement x)
```

副本的数据是共享的(浅拷贝) :修改一个节点也将改变其他。如果你想使一个深拷贝,使用[cloneNode](qdomnode.html#cloneNode)( ) 。
```
