X11: raise an existing window via command line?

Given an X client window ID, is there a way to raise that window from the command line?

$ xlsclients -a
Window 0x3000001:
  Machine:  ohm
  Name:  Terminal
  Icon Name:  foo
  Command:  foo
  Instance/Class:  foo/bar

$ xraise -id 0x3000001   <-- this is what I would like to do

EDIT: Inserting the code in the answer :

#include <X11/Xos.h>
#include <X11/Xlib.h>
#include <X11/Xutil.h>
#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>

Window Window_With_Name(dpy, top, name)
     Display *dpy;
     Window top;
     char *name;
{
	Window *children, dummy;
	unsigned int nchildren;
	int i;
	Window w=0;
	char *window_name;

	if (XFetchName(dpy, top, &window_name) && (strstr(window_name, name) == window_name))
	  return(top);

	if (!XQueryTree(dpy, top, &dummy, &dummy, &children, &nchildren))
	  return(0);

	for (i=0; i<nchildren; i++)
       	{
		w = Window_With_Name(dpy, children[i], name);
		if (w)
		  break;
	}
	if (children) XFree ((char *)children);
	  return(w);
}

int main(int argc, char **argv)
{
	Window window;
	Display *dpy;

	if (argc < 2)
	{
		fprintf(stderr, "Usage: %s window-name\n", argv[0]);
		exit(1);
	}

	dpy = XOpenDisplay(":0");
	if (!dpy)
	{
		fprintf(stderr, "Cannot open display.\n");
		exit(1);
	}

	window = Window_With_Name(dpy, DefaultRootWindow(dpy), argv[1]);
	if (!window)
	{
		fprintf(stderr, "Cannot find a window by that name.\n");
		exit(1);
	}

	XSetInputFocus(dpy, window, RevertToPointerRoot, CurrentTime);
	if(!XRaiseWindow(dpy, window))
	{
		fprintf(stderr, "XRaiseWindow error?\n");
		exit(1);
	}

	XCloseDisplay(dpy);
}

You can also use wmctrl, which does similar things
