NET Blogger API

A little help for query-ing blog feeds

The function is self-explaining...but I just make it clear.

You pass parameters such as Label, MaxResult, StartIndex and keyword to search

Label: HarryPotter

MaxResult: 10

StartIndex: 1

http://myblog.blogspot.com/feeds/posts/default/-/HarryPottermax-results\07510&start-index\0751&orderby=updated

The keyword search doesn\47t seem to work yet. I wonder why too.

Anyway this just serves as it, in case you are lazy to form the query. 

Any enhancements are welcome :)
