## org.apache.poi.xssf.eventusermodel
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" />
         </rPr>
         <t xml:space="preserve">Causes Problems</t>
       </r>
     </si>
     <si>
       <t>This does not</t>
     </si>
    </sst>
