## org.apache.poi.xssf.extractor
Class XSSFExportToXml

    java.lang.Object
      org.apache.poi.xssf.extractor.XSSFExportToXml

All Implemented Interfaces:
  java.util.Comparator

    public class XSSFExportToXml

extends java.lang.Object
implements java.util.Comparator

Maps an XLSX to an XML according to one of the mapping defined. The output XML Schema must respect this limitations:

- all mandatory elements and attributes must be mapped (enable validation to check this)
- no <any> in complex type/element declaration
- no <anyAttribute> attributes declaration
- no recursive structures: recursive structures can't be nested more than one level
- no abstract elements: abstract complex types can be declared but must not be used in elements.
- no mixed content: an element can't contain simple text and child element(s) together
- no <substitutionGroup> in complex type/element declaration

Constructor Summary
`XSSFExportToXml(XSSFMap map)` Creates a new exporter and sets the mapping to be used when generating the XML output document

Method Summary
`int` | `compare(java.lang.Object in_leftXpath, java.lang.Object in_rightXpath)` Compares two xpaths to define an ordering according to the XML Schema
`void` | `exportToXML(java.io.OutputStream os, boolean validate)` Exports the data in an XML stream
`void` | `exportToXML(java.io.OutputStream os, java.lang.String encoding, boolean validate)` Exports the data in an XML stream
