  //I have to make this interactive, the user will enter the country required, via an input box on a form, XPath will then return the correct values...can you help with the syntax for this... //

  You may use a simple string concatenation to get a desired XPath expression. However, be sure to check the input first in order to avoid XPath injection attack: http://www.webappsec.org/projects/threat/classes/xpath_injection.shtml.

  Hi Martin, thanks very much..XPath, seems the way to go...I can also use it to find items that are greater than a specifc value. I have one problem though, I have to make this interactive, the user will enter the country required, via an input box on a form, XPath will then return the correct values...can you help with the syntax for this...
  
  thank you very much

  Hi,

  I have 2 javascript functions as below:

  function cbload()

  {

  var obj2=null;

  var obj=null;

  var obj1=document;

  obj2=obj1.getElementById("parId");

  for (i=0;i<5;i++)

  {

  obj=obj1.createElement("div");

  obj.id="div_" + i.toString();

  obj2.appendChild(obj);

  obj=null;

  }

  obj=null;

  obj2=null;

  obj1=null;

  alert('done');

  }

  function cbunload()

  {

  var obj2=null;

  var obj=null;

  var obj1=document;

  obj2=obj1.getElementById("parId");

  obj=null;

  for (i=0;i<5;i++)

  {

  obj=obj1.getElementById("div_" + i.toString());

  obj2.removeChild(obj);

  obj=null;

  }

  obj=null;

  obj2=null;

  obj1=null;

  alert('done');

  }

  <input id="Submit1" type="button" value="Load" onclick="cbload()" />

  <input id="Button1" type="button" value="UnLoad" onclick="cbunload()" />

  when i see it using Drip-it tool, After a Load/Unload, I am still seeing DOM Leak as div_0 thru div_4.

  Can someone help me in how to completly remove this leak.

  Help will be much appreciated

  Do you know XPath With IE 6 and later you can use XPath to select/find nodes in an XML DOM document, see the selectNodes/selectSingleNode methods.

  Mozilla and Opera 9 also support XPath, although with a completely different API, the W3C DOM Level 3 XPath API.

  You would first find the country element with an XPath expression e.g.

  //country[@name = 'Albania']

  then you could use relative XPath expressions e.g.

  coasts

  to find all coasts element in that country element selected earlier.
