Class XSSFExportToXml

java.lang.Object

org.apache.poi.xssf.extractor.XSSFExportToXml

All Implemented Interfaces:

Comparator<String>

public class XSSFExportToXml
extends Object
implements Comparator<String>

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
