OBSERVATIONS / DISCUSSION OF RESULT:
Comparing Different XML Serialization Formats and Their Impact on Data
Size and Processing
XML:
Size: 4,548 bytes
Time to parse:
0.0014450550079345703s CXML:
Size: 4,548 bytes
Time to parse:
0.0010936260223388672s BXML:
Size: 4,548 bytes
Time to parse: 0.001340627670288086s
The file size for all is the same though the parsing time is best in this order
CXML>BXML>XML
Academic Year 2023-24
SAP ID: 60003200124
CONCLUSION:
In this experiment, three different XML serialization formats, namely XML, CXML, and BXML,
were created and analyzed for their impact on data size and processing time in the context of
parsing using Google Colab. While all three formats resulted in identical file sizes of 4,548
bytes, the parsing time varied slightly. Notably, CXML demonstrated the fastest parsing time
at 0.0010936 seconds, followed by XML at 0.0014451 seconds, and BXML at 0.0013406
seconds. The experiment indicates that the choice of serialization format can influence
parsing efficiency, with CXML exhibiting the most optimal performance in terms of
processing time. These findings emphasize the importance of considering both file size and
parsing time when selecting an XML serialization format for specific applications or systems.
