    • compare

      public int compare(String url1, String url2) throws IOException
      Compares the two XML documents located at the given URL locations. Returns 0, if no differences are found, otherwise returns a positive number indicating the number of differences.
      Parameters:
      url1 - the location of the XML document to compare.
      url2 - the location of the XML document to compare against url1.
      Returns:
      0, if no differences are found, otherwise a positive number indicating the number of differences.
      Throws:
      IOException
    • compare

      public int compare(XPathNode node1, XPathNode node2)
      Compares the given XPathNodes. Returns 0, if no differences are found, otherwise returns a positive number indicating the number of differences.
      Parameters:
      node1 - the XPathNode to compare with.
      node2 - the XPathNode being compared against node1.
      Returns:
      0, if no differences are found, otherwise a positive number indicating the number of differences.
    • compare

      public int compare(XPathNode node1, String filename1, XPathNode node2, String filename2)
      Compares the given XPathNodes. Returns 0, if no differences are found, otherwise returns a positive number indicating the number of differences.
      Parameters:
      node1 - the XPathNode to compare with.
      node2 - the XPathNode being compared against node1.
      Returns:
      0, if no differences are found, otherwise a positive number indicating the number of differences.
    • setIgnoreChildOrder

      public void setIgnoreChildOrder(boolean ignoreOrder)
      Sets the flag for whether or not the order of element children should be ignored. By default this value is true, indicating that element ordering is not important. If order is important, set this value to false.
      Parameters:
      ignoreOrder - a boolean that when true indicates that child order is not important.
    • setIgnoreWhitespace

      public void setIgnoreWhitespace(boolean ignoreWhitespace)
      Sets the flag for whether or not "ignorable" whitespace should in fact be ignored. By default this value is "true", indicating that all ignorable whitespace is ignored.
      Parameters:
      ignoreWhitespace - a boolean that when true indicates that all ignorable whitespace should in fact be ignored. If false, then differeces in whitespace will be reported.
    • setReturnOnFirstDifference

      public void setReturnOnFirstDifference(boolean returnOnFirst)
      Sets the flag for whether or not to return immediately upon first difference found. This is useful when using the diff tool just to determine if two XPathNodes or files are XML-equivalent without enumerating all the differences.
      Parameters:
      returnOnFirst - the boolean that when true indicates that the diff should terminate immediate upon first difference.
    • main

      public static void main(String[] args)
      main method, for command line invocation
      Parameters:
      args - an array of arguments
