If it does not find an +encoding declaration, then it assumes that the data is either in +UTF-8 or UTF-16, depending on whether it can find a byte-order +mark. +<p> There are two ways to populate the input source with data: you can +construct it with a <a href="qiodevice.html">TQIODevice</a>* so that the input source reads the +data from that device. Or you can set the data explicitly with one +of the <a href="#setData">setData</a>() functions. +<p> Usually you either construct a TQXmlInputSource that works on a +TQIODevice* or you construct an empty TQXmlInputSource and set the +data with setData(). There are only rare occasions where you would +want to mix both methods. +<p> The TQXmlReader subclasses use the <a href="#next">next</a>() function to read the +input character by character. If you want to start from the +beginning again, use <a href="#reset">reset</a>(). +<p> The functions <a href="#data">data</a>() and <a href="#fetchData">fetchData</a>() are useful if you want to do +something with the data other than parsing, e.g. displaying the +raw XML file. The benefit of using the TQXmlInputClass in such +cases is that it tries to use the correct encoding. +<p> <p>See also <a href="qxmlreader.html">TQXmlReader</a>, <a href="qxmlsimplereader.html">TQXmlSimpleReader</a>, and <a href="xml-tools.html">XML</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQXmlInputSource"></a>TQXmlInputSource::TQXmlInputSource () +</h3> +Constructs an input source which contains no data. +<p> <p>See also <a href="#setData">setData</a>(). + +<h3 class=fn><a name="TQXmlInputSource-2"></a>TQXmlInputSource::TQXmlInputSource ( <a href="qiodevice.html">TQIODevice</a> * dev ) +</h3> +Constructs an input source and gets the data from device <em>dev</em>. +If <em>dev</em> is not open, it is opened in read-only mode.
