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.

CkPython

import chilkat

# Note: This example requires Chilkat v9.5.0.64 or later.

# Add some entries to a hashtable.
hashTab = chilkat.CkHashtable()

hashTab.AddStr("aaa","111")
hashTab.AddStr("bbb","222")
hashTab.AddStr("ccc","333")

# Serialize to XML
sb = chilkat.CkStringBuilder()
hashTab.ToXmlSb(sb)
print(sb.getAsString())
print("---")

# 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()
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()
hashTab2.GetKeys(sTable)

i = 0
numKeys = sTable.get_Count()
while i < numKeys :
    key = sTable.stringAt(i)
    print(key + ": " + hashTab2.lookupStr(key))
    i = i + 1
