(JavaScript) Serialize / Deserialize Hashtable to/from XML
Demonstrates how to seralize / deserialize a Hashtable to/from XML.
Note: This example requires Chilkat v9.5.0.64 or later.
// Note: This example requires Chilkat v9.5.0.64 or later.
// Add some entries to a hashtable.
var hashTab = new CkHashtable();
hashTab.AddStr("aaa","111");
hashTab.AddStr("bbb","222");
hashTab.AddStr("ccc","333");
// Serialize to XML
var sb = new CkStringBuilder();
hashTab.ToXmlSb(sb);
console.log(sb.GetAsString());
console.log("---");
// The output is as follows. Each hash table entry
// is contained in an "e" node. The entry's key
// is in the "k" node, and the value in the "v" node.
// <?xml version="1.0" encoding="utf8-8"?>
// <hashtable>
// <e><k>aaa</k><v>111</v></e>
// <e><k>bbb</k><v>222</v></e>
// <e><k>ccc</k><v>333</v></e>
// </hashtable>
//
// Now load (deserialize) into a new hash table.
var hashTab2 = new CkHashtable();
hashTab2.AddFromXmlSb(sb);
// Get the hash table keys, and lookup each (to show
// that the hash table was correctly deserialized).
// The GetKeys method can return the keys in any order.
var sTable = new CkStringTable();
hashTab2.GetKeys(sTable);
var i = 0;
var numKeys = sTable.Count;
while (i < numKeys) {
var key = sTable.StringAt(i);
console.log(key + ": " + hashTab2.LookupStr(key));
i = i+1;
}
