(Ruby) 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.
require 'chilkat' # Note: This example requires Chilkat v9.5.0.64 or later. # Add some entries to a hashtable. hashTab = Chilkat::CkHashtable.new() hashTab.AddStr("aaa","111") hashTab.AddStr("bbb","222") hashTab.AddStr("ccc","333") # Serialize to XML sb = Chilkat::CkStringBuilder.new() hashTab.ToXmlSb(sb) print sb.getAsString() + "\n"; print "---" + "\n"; # 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. hashTab2 = Chilkat::CkHashtable.new() 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. sTable = Chilkat::CkStringTable.new() hashTab2.GetKeys(sTable) i = 0 numKeys = sTable.get_Count() while i < numKeys key = sTable.stringAt(i) print key + ": " + hashTab2.lookupStr(key) + "\n"; i = i + 1 end |
