YML format

YML (Yandex Market Language) is a standard developed by Yandex that is used to accept and post information in the Yandex.Market database. YML is based on the XML standard.

Requirements for YML files

The YML standard does not support nonprintable characters with ASCII codes 0 through 31 (except for characters 9, 10, and 13 — tab, new line, and carriage return).
The ", &, >, <, and ' characters need to be replaced with their equivalent codes:
Symbol in text
Code for the YML file
" & > < '
" & > < '
Symbol in text
Code for the YML file
" & > < '
" & > < '
Note. You can use the characters ", &, >, <, 'in the CDATA section in the app description.
Acceptable YML file encodings: UTF-8, windows-1251.

Symbol in text	Code for the YML file
`" & > < '`	`" & > < '`

Symbol in text	Code for the YML file
`" & > < '`	`" & > < '`
