Example usage for javax.xml.parsers DocumentBuilderFactory setIgnoringElementContentWhitespace

Introduction

In this page you can find the example usage for javax.xml.parsers DocumentBuilderFactory setIgnoringElementContentWhitespace.

Prototype

public void setIgnoringElementContentWhitespace(boolean whitespace) 

Source Link

Document

Specifies that the parsers created by this factory must eliminate whitespace in element content (sometimes known loosely as 'ignorable whitespace') when parsing XML documents (see XML Rec 2.10).
