Hi,
I am searching for a code snippet that would convert a malformed XML string to a well formed one. Please let me know if any of you have it or a link to one such code snippet.
Thanks

Tip 5, line # test.init(); —> will give a compile error. You need to pass the filestream to the init() function. Otherwise its a good example.

Of course it should be a.length, sorry me

a = java.util.Arrays.copyOf(a, a.length * 2 + 1);

A complete method would look similar to this:

private static void resizeArray(T[] a, int size) {
if (size < 0) {
throw new IllegalArgumentException();
}

return java.util.Arrays.copyOf(a, size);
}

There is an even better solution for resizing an array:

int[] a = new int[10];

// roughly doubling the array size
a = java.util.Arrays.copyOf(a, a.size * 2 + 1);
