Script Preparation code:

var arrComments = []; // Create empty array for the comment nodes

// Create a NodeIterator object with all comment nodes in the <table class="ms-formtable"...>
var nodeIterator = document.createNodeIterator(
    document.body,
    NodeFilter.SHOW_COMMENT,    
    function acceptNode(node) {
		return NodeFilter.FILTER_ACCEPT;
	}, false 
);

// Add all the comment nodes of the nodeIterator to the arrComments array
while(nextNode = nodeIterator.nextNode()){
	arrComments.push(nextNode);
}

Tests:

filter
arrComments.getNodeFilter = function(strID) { var objRegExp = new RegExp("id='" + strID + "'"); var commentNode = arrComments.filter(function(comCurrent){ if(objRegExp.test(comCurrent.textContent) == true) return comCurrent; })[0]; return commentNode; } console.log(arrComments.getNodeFilter('t97')); console.log(arrComments.getNodeFilter('t87')); console.log(arrComments.getNodeFilter('t95')); console.log(arrComments.getNodeFilter('t3')); console.log(arrComments.getNodeFilter('t12'));
for loop
arrComments.getNodeForLoop = function(strID) { var objRegExp = new RegExp("id='" + strID + "'"); for(var i = 0; i < this.length; i++) { var commentNode = this[i]; if(objRegExp.test(commentNode.textContent) == true) return commentNode; }; } console.log(arrComments.getNodeForLoop('t97')); console.log(arrComments.getNodeForLoop('t87')); console.log(arrComments.getNodeForLoop('t95')); console.log(arrComments.getNodeForLoop('t3')); console.log(arrComments.getNodeForLoop('t12'));
