<h2 id="details">Detailed Description</h2>
<p>The <a href="qxmlstreamattributes.html">QXmlStreamAttributes</a> class represents a vector of <a href="qxmlstreamattribute.html">QXmlStreamAttribute</a>.</p>
<p>Attributes are returned by a <a href="qxmlstreamreader.html">QXmlStreamReader</a> in <a href="qxmlstreamreader.html#attributes">attributes()</a> when the reader reports a <a href="qxmlstreamreader.html#TokenType-enum">start element</a>. The class can also be used with a <a href="qxmlstreamwriter.html">QXmlStreamWriter</a> as an argument to <a href="qxmlstreamwriter.html#writeAttributes">writeAttributes()</a>.</p>
<p>The convenience function <a href="qxmlstreamattributes.html#value">value</a>() loops over the vector and returns an attribute value for a given namespaceUri and an attribute's name.</p>
<p>New attributes can be added with <a href="qxmlstreamattributes.html#append">append</a>().</p>

<p>Returns <code>true</code> if this <a href="qxmlstreamattributes.html">QXmlStreamAttributes</a> has an attribute whose qualified name is <i>qualifiedName</i>; otherwise returns <code>false</code>.</p>
<p>Note that this is not namespace aware. For instance, if this <a href="qxmlstreamattributes.html">QXmlStreamAttributes</a> contains an attribute whose lexical name is &quot;xlink:href&quot; this doesn't tell that an attribute named <code>href</code> in the XLink namespace is present, since the <code>xlink</code> prefix can be bound to any namespace. Use the overload that takes a namespace URI and a local name as parameter, for namespace aware code.</p>

<p>This is an overloaded function.</p>
<p>Returns the value of the attribute with qualified name <i>qualifiedName</i> , or an empty string reference if the attribute is not defined. A qualified name is the raw name of an attribute in the XML data. It consists of the namespace prefix, followed by colon, followed by the attribute's local name. Since the namespace prefix is not unique (the same prefix can point to different namespaces and different prefixes can point to the same namespace), you shouldn't use qualified names, but a resolved namespaceUri and the attribute's local name.</p>
