Demonstrate XML SearchForTag2

Demonstrates how to use SearchForTag2. React Native

import { StringBuilder, Xml } from '@chilkat/react-native'

function chilkatExample() {
  const xml = new Xml();

  // Load the following XML:

  // 	<Test>
  // 	    <testchild1>
  // 	        test
  // 	    </testchild1>
  // 	    <testchild1>
  // 	        test1
  // 	    </testchild1>
  // 	    <testchild1>
  // 	        test2
  // 	    </testchild1>
  // 	    <testchild1>
  // 	        test3
  // 	    </testchild1>
  // 	    <testchild1>
  // 	        test4
  // 	    </testchild1>
  // 	    <testchild1>
  // 	        test5
  // 	    </testchild1>

    i++;

    // Set afterPtr = xmlSearch (so we find the next match after the one we just found)
    // Rest xmlSearch to the root of the XML tree to be searched.
