Generally, you probably want the error string ( <a class="el" href="classTiXmlDocument.html#9d0f689f6e09ea494ea547be8d79c25e">ErrorDesc()</a> ). 
<p>
But if you prefer the ErrorId, this function will fetch it.

Returns the location (if known) of the error. 
<p>
The first column is column 1, and the first row is row 1. A value of 0 means the row and column wasn't applicable (memory errors, for example, have no row/column) or the parser lost the error. (An error in the error reporting, in that case.)<p>

<a class="el" href="classTiXmlDocument.html#51dac56316f89b35bdb7d0d433ba988e">SetTabSize()</a> allows the error reporting functions (<a class="el" href="classTiXmlDocument.html#f30efc75e804aa2e92fb8be3a8cb676e">ErrorRow()</a> and <a class="el" href="classTiXmlDocument.html#a90bc630ee5203c6109ca5fad3323649">ErrorCol()</a>) to report the correct values for row and column. 
<p>
It does not change the output or input in any way.<p>
By calling this method, with a tab size greater than 0, the row and column of each node and attribute is stored when the file is loaded. Very useful for tracking the DOM back in to the source file.<p>
The tab size is required for calculating the location of nodes. If not set, the default of 4 is used. The tabsize is set per document. Setting the tabsize to 0 disables row/column tracking.<p>
Note that row and column tracking is not supported when using operator&gt;&gt;.<p>
The tab size needs to be enabled before the parse or load. Correct usage: <div class="fragment"><pre class="fragment">		TiXmlDocument doc;
		doc.SetTabSize( 8 );
		doc.Load( "myfile.xml" );
		</pre></div><p>
