If you do not +want to change the value of the element's attribute you must +use <a href="qdomnode.html#cloneNode">cloneNode</a>() to get an independent copy of the attribute. +<p> QDomAttr can return the <a href="#name">name</a>() and <a href="#value">value</a>() of an attribute. An +attribute's value is set with <a href="#setValue">setValue</a>(). If <a href="#specified">specified</a>() returns +TRUE the value was either set in the document or set with +setValue(); otherwise the value hasn't been set. The node this +attribute is attached to (if any) is returned by <a href="#ownerElement">ownerElement</a>(). +<p> For further information about the Document Object Model see +<a href="http://www.w3.org/TR/REC-DOM-Level-1/">http://www.w3.org/TR/REC-DOM-Level-1/</a> and +<a href="http://www.w3.org/TR/DOM-Level-2-Core/">http://www.w3.org/TR/DOM-Level-2-Core/</a>. +For a more general introduction of the DOM implementation see the +<a href="qdomdocument.html">QDomDocument</a> documentation. +<p>See also <a href="xml-tools.html">XML</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="QDomAttr"></a>QDomAttr::QDomAttr () +</h3> +Constructs an empty attribute. + +<h3 class=fn><a name="QDomAttr-2"></a>QDomAttr::QDomAttr ( const <a href="qdomattr.html">QDomAttr</a> & x ) +</h3> +Constructs a copy of <em>x</em>. +<p> The data of the copy is shared (shallow copy): modifying one node +will also change the other.
