Although the POI's capabilities are considerable, the process of extracting text is simple.
As shown here, a
FileInputStream
object representing the file,
TestDocu-
ment.docx
, is used by the
ExtractorFactory
class'
createExtractor
method
to select the appropriate
POITextExtractor
instance. This is the base class for sever-
al different extractors. The
getText
method is applied to the extractor to get the text:
try {
FileInputStream fis =
new FileInputStream("TestDocument.docx");
POITextExtractor textExtractor =
ExtractorFactory.createExtractor(fis);
System.out.println(textExtractor.getText());
} catch (IOException ex) {
// Handle exceptions
} catch (OpenXML4JException | XmlException ex) {
// Handle exceptions
}
A part of the output is as follows:

known as buccaneers, corsairs, and privateers. In

It can be useful to know more about a Word document. POI supports a
POIXMLProper-
tiesTextExtractor
class that gives us access to core, extended, and custom proper-
ties of a document. There are two ways of readily getting a string containing many of
these properties.
