Welcome to the libcsn wiki!

libcsn is a C library to search and get metadata from chiasenhac.com, which is a (kinda) popular music sharing site, with good embedded metadata and high quality music (That's their claim, I'm not really sure since I'm no music expert)

Searching

• Since the new chiasenhac site uses an API to search, returning a data as json format, searching became less painful

$ curl 'https://chiasenhac.vn/search/real?q=shallow&type=json&rows=1&view_all=true'

shall return

[

Fetching song and album info

Fetching

Currently there are 2 sites to fetch:

• The old site which is old and no HTTP only, loads faster however it might be deleted someday
• The new site is good to go although its structure could be change in the future

Parsing

• XPATH
• SAX
