Class ReadOnlySharedStringsTable

java.lang.Object

org.xml.sax.helpers.DefaultHandler

org.apache.poi.xssf.eventusermodel.ReadOnlySharedStringsTable

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

public class ReadOnlySharedStringsTable
extends org.xml.sax.helpers.DefaultHandler

This is a lightweight way to process the Shared Strings table. Most of the text cells will reference something from in here.

Note that each SI entry can have multiple T elements, if the string is made up of bits with different formatting.

Example input:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<sst xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main" count="2" uniqueCount="2">
 <si>
   <r>
     <rPr>
       <b />
       <sz val="11" />
       <color theme="1" />
       <rFont val="Calibri" />
       <family val="2" />
       <scheme val="minor" />
     </rPr>
     <t>This:</t>
   </r>
   <r>
     <rPr>
       <sz val="11" />
       <color theme="1" />
       <rFont val="Calibri" />
       <family val="2" />
       <scheme val="minor" />
