(Xojo Plugin) Serialize / Deserialize Hashtable to/from XMLDemonstrates 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. Dim hashTab As New Chilkat.Hashtable Dim success As Boolean success = hashTab.AddStr("aaa","111") success = hashTab.AddStr("bbb","222") success = hashTab.AddStr("ccc","333") // Serialize to XML Dim sb As New Chilkat.StringBuilder success = hashTab.ToXmlSb(sb) System.DebugLog(sb.GetAsString()) System.DebugLog("---") // 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. Dim hashTab2 As New Chilkat.Hashtable success = 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. Dim sTable As New Chilkat.StringTable success = hashTab2.GetKeys(sTable) Dim i As Int32 i = 0 Dim numKeys As Int32 numKeys = sTable.Count While i < numKeys Dim key As String key = sTable.StringAt(i) System.DebugLog(key + ": " + hashTab2.LookupStr(key)) i = i + 1 Wend |
