parsing - How do you build an XML parser? -

-

can direct me tutorial in building xml parser? realize languages have libraries task, i'm interested in learning grammar of xml , theory behind how parsers work. i've tried searching explains have been unable find anything.

i think there isn't enough demand people write such tutorials; , commented, don't think general parser techniques of help. xml parsers not usual lex+yacc approach works (lexer part more parser, that's worth).

i know production ready xml parsers beasts, might best off starting reading one. java has few examples, , xmlpull might amongst simplest proper parsers. woodstox , xerces compliant ("full") parsers, large codebase, not light reading. handle xml parser should, might educational too. beware half-backed fake parsers skip checks things xml specification mandates (javolution example checks few things, example none of character validity checks, or attribute name duplications).

another thing read xml specification. 1 of well-written specifications imo; accurate , complete, if not light reading. considering covers, it's not long.

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
