Class XmlLineNumberParser

java.lang.Object

org.apache.camel.parser.helper.XmlLineNumberParser

public final class XmlLineNumberParser
extends Object

An XML parser that uses SAX to include line and column number for each XML element in the parsed Document.

The line number and column number can be obtained from a Node/Element using

 String lineNumber = (String) node.getUserData(XmlLineNumberParser.LINE_NUMBER);
 String lineNumberEnd = (String) node.getUserData(XmlLineNumberParser.LINE_NUMBER_END);
 String columnNumber = (String) node.getUserData(XmlLineNumberParser.COLUMN_NUMBER);
 String columnNumberEnd = (String) node.getUserData(XmlLineNumberParser.COLUMN_NUMBER_END);
 

Mind that start and end numbers are the same for single-level XML tags.
