A parser is a program that is part of the compiler, and parsing is part of the compiling process. Parsing happens during the analysis stage of compilation. In parsing, code is taken from the preprocessor, broken into smaller pieces and analyzed so other software can understand it. The parser...

EDIT: You need to have an understanding with the sender on the delimiter, and then it is the sender's responsibility to ensure the data qualtity. Looking at your sample data, '|CRLF' seems to be a good delimiter instead of 'CRLF'. But how do you(the parser) make su...

that method, it is also called LL,LR,SLR or LALR (k). LL(k) means a top-down parser can be created for the parser with a max lookahead of k symbols. LR(k) means a bottom-up parser can be created for the parser with a max lookahead of k symbols. LALR(1) grammars are a subs...

According to the MSXML team, the new internal XML 1.0 parser is about twice as fast as the existing parser. The MSXML 4.0 SAX implementation uses this new parser by default, but the DOM implementation doesn't. However, you can coerce a DOMDocument into using the new parser by calling setPr...
“[…] let’s end with an example of a piece of iOS software that is pure craft: Things. Things on iPad and iPhone is one of the most tactile, fast-as-you-can-move apps around. Each animation is purposeful.Mainly, it is fun. It’s a fun app to be in. To put stuff into, to...
finding the end of an element etc., the parser calls theeventHandlerwith parameters describing the event. ThecommAreaoperand is a variable that is passed as a parameter to theeventHandlerproviding a way for the XML-SAX operation code to communicate with the handling procedure. When theeventHandl...
The rest is detail. It's the expressive power of the tilde and the caret that explains why people use them much more than the simpler .x syntax: they simply let you do more. That's why you'll see the tilde used often even where .x would serve. As an example, see npm itself: it...
