|
|---|
| 79 |
|
|---|
| 80 |
|
|---|
| 81 |
|
|---|
| 82 | The QDomElement class represents one element in the DOM tree.
|
|---|
| 83 |
|
|---|
| 84 | <p>
|
|---|
| 85 |
|
|---|
| 86 | <p> Elements have a <a href="#tagName">tagName</a>() and zero or more attributes associated
|
|---|
| 87 | with them. The tag name can be changed with <a href="#setTagName">setTagName</a>().
|
|---|
| 88 | <p> Element attributes are represented by <a href="qdomattr.html">QDomAttr</a> objects that can
|
|---|
| 89 | be queried using the <a href="#attribute">attribute</a>() and <a href="#attributeNode">attributeNode</a>() functions.
|
|---|
| 90 | You can set attributes with the <a href="#setAttribute">setAttribute</a>() and
|
|---|
| 91 | <a href="#setAttributeNode">setAttributeNode</a>() functions. Attributes can be removed with
|
|---|
| 92 | <a href="#removeAttribute">removeAttribute</a>(). There are namespace-aware equivalents to these
|
|---|
| 93 | functions, i.e. <a href="#setAttributeNS">setAttributeNS</a>(), <a href="#setAttributeNodeNS">setAttributeNodeNS</a>() and
|
|---|
| 94 | <a href="#removeAttributeNS">removeAttributeNS</a>().
|
|---|
| 95 | <p> If you want to access the text of a node use <a href="#text">text</a>(), e.g.
|
|---|
| 96 | <pre>
|
|---|
| 97 | QDomElement e = //...
|
|---|
| 98 | //...
|
|---|
| 99 | <a href="qstring.html">QString</a> s = e.<a href="#text">text</a>()
|
|---|
| 100 | </pre>
|
|---|
| 101 |
|
|---|
| 102 | The text() function operates recursively to find the text (since
|
|---|
| 103 | not all elements contain text). If you want to find all the text
|
|---|
| 104 | in all of a node's children, iterate over the children looking for
|
|---|
| 105 | <a href="qdomtext.html">QDomText</a> nodes, e.g.
|
|---|
| 106 | <pre>
|
|---|
| 107 | <a href="qstring.html">QString</a> text;
|
|---|
| 108 | QDomElement element = doc.documentElement();
|
|---|
| 109 | for( <a href="qdomnode.html">QDomNode</a> n = element.<a href="qdomnode.html#firstChild">firstChild</a>(); !n.<a href="qdomnode.html#isNull">isNull</a>(); n = n.<a href="qdomnode.html#nextSibling">nextSibling</a>() )
|
|---|
| 110 | {
|
|---|
| 111 | <a href="qdomtext.html">QDomText</a> t = n.<a href="qdomnode.html#toText">toText</a>();
|
|---|
| 112 | if ( !t.<a href="qdomnode.html#isNull">isNull</a>() )
|
|---|
| 113 | text += t.<a href="qdomcharacterdata.html#data">data</a>();
|
|---|
| 114 | }
|
|---|
| 115 | </pre>
|
|---|
| 116 |
|
|---|
| 117 | Note that we attempt to convert each node to a text node and use
|
|---|
| 118 | <a href="#text">text</a>() rather than using <a href="qdomnode.html#firstChild">firstChild</a>().<a href="qdomnode.html#toText">toText</a>().data() or
|
|---|
| 119 | n.toText().data() directly on the node, because the node may not
|
|---|
| 120 | be a text element.
|
|---|
| 121 | <p> You can get a list of all the decendents of an element which have
|
|---|
| 122 | a specified tag name with <a href="#elementsByTagName">elementsByTagName</a>() or
|
|---|
| 123 | <a href="#elementsByTagNameNS">elementsByTagNameNS</a>().
