<div class="helpdiv" id="chapters_indexdatafile">"XML file for chapters" defines the parameter <br/> <i><strong>IndexDataFile</strong></i> for the <em>Chapters</em> Plugin/Add-on.<br/><br/><strong>Parameter description:</strong><br/>Alternatively to the &quot;IndexData&quot; parameter you can use an external XML file to provide the XML document structure data required for this plug-in. The XML file must be located in the same domain as FSI Viewer to avoid cross-domain security restrictions. If you enter a relative path, FSI Viewer loads the file from the subdirectoy &quot;pages_xml&quot; of your FSI Viewer configuration directory (&quot;FSIBase&quot;)<br/> If you store XML files in the directory &quot;/[fsi]/config/pages_xml/&quot; you therefore only need to specify the file name of the XML file to load.<br/> <br/> Please note: You need to use an external XML file in UTF-8 format when using special language specific characters (characters &gt;= 0x80).<br/><br/><strong>Sample from configuration file:</strong><div class="samplecontents"><pre>&lt;PLUGIN src=&quot;chapters&quot;&gt;
&lt;IndexDataFile value=&quot;chapters.xml&quot; /&gt;
&lt;/PLUGIN&gt;</pre></div></div>
