MongoDB $bitsAllClear with BinData - how it works?

Does anyone knows how the mongodb $bitsAllClear works?
I ready the document from https://docs.mongodb.com/manual/reference/operator/query/bitsAllClear/ i am trying to understand how can i create a BinData from a bitmask
For example the documentation says:
(the binary representation of BinData(0, "ID==") is 00010100.
How can i transform the 00010100 to binary to insert in the document? Is there any online converted to try?
(the binary representation of BinData(0, "ID==") is 00010100.
This example looks incorrect to me. BinData takes a base64 encoded string as its second argument, and the base64 encoding of 00010100 is FA==. Other examples on that same page look correct, so I suspect it's a typo.
In node, you can do the conversion from a binary string to base64 like so:
const hexString = parseInt('00010100', 2).toString(16);
Buffer.from(hexString, 'hex').toString("base64") // FA==

Convert specific symbols to normal utf-8 from json

I get json string from server. Then I parser it using SBJSON library. But when I show parse results in my label I have symbols like that
!
(normally it's !).
So how can I convert my json string to normal string?
Use this: https://github.com/mwaterfall/MWFeedParser/blob/master/Classes/NSString+HTML.m (specifically, the stringByDecodingHTMLEntities method).

Save to pdf from a weird string

From my XML file, I got a weird string (I think it's a blob data).
It looks like this:
0x244033242D212E430D21E2E3[.......]
It's a very very long string. My DB administrator told me that it comes from the database.
How to convert this string to a valid PDF file?
Thank you very much.
Regards,
Kael
A lot depends the database's manner of storing blob data, but if the format's not too exotic then the NSData and NSPropertyListSerialization classes should be able to convert it into something manageable.

How to convert byte array to NSString

xml parser, in iPhone

Am getting date (10/02/2011) in xmlresponse how to get this value in to string using NSXmlParserDelegate. "/" blocks me and am not getting how to handle this..
Thanks in advance..
Use NSDateFormatter to get date from NSString from any formats.
You have not been clear where this xml data is coming from, I couldnt turn anything up on how dates should be formatted in xml. The first thought is "you are doing it wrong" if you can try using a different separator for dates, parse them out of the stream before you give the data to NSXMLParser. I know which I would prefer.
