dom xml parser java, same tags -

-

i have xml document has varying number of same named tags. how can count of child elements , value of it.

    <question>                 <questiontext>abc?</questiontext>                 <option>a1 - xyz</option>                 <option>a2 - wxy</option>                 <option>a2 - hjk</option>                 <id>1</id>             </question>     <question>    <questiontext>ery?</questiontext> <questiontext>nnn?</questiontext> <questiontext>kkkk?</questiontext> <id>2</id>             </question>

the output should read...

id:2 has 1 questiontext , 3 option questiontext 1:abc? option 1:a1 - xyz option 2:a2 - wxy option 3:a2 - hjk

id:1 has 3 questiontext , 0 option questiontext 1.ery? questiontext 2.nnn? questiontext 3.kkkk?

i tried, gives fault results

    element eelement = (element) nnode;         for(int i=0;i<eelement.getchildnodes().getlength();i++){ system.out.println("nodename:"+eelement.getnodename()); system.out.println("tag value:"+gettagvalue("questiontext",eelement)); system.out.println("tag value:"+gettagvalue("option",eelement));     }  private static string gettagvalue(string stag, element eelement){     nodelist nllist= eelement.getelementsbytagname(stag).item(0).getchildnodes();     node nvalue = (node) nllist.item(0);       return nvalue.getnodevalue();     }

after doing research found solution

        element eelement = (element) nnode;   gettagvalue("questiontext",eelement); gettagvalue("option",eelement);      private static void gettagvalue(string stag, element eelement){             nodelist nllist = eelement.getelementsbytagname(stag);             system.out.println("size of nodelist:"+nllist.getlength());             for(int i=0;i<nllist.getlength();i++){                 nodelist klist= eelement.getelementsbytagname(stag).item(i).getchildnodes();                 node kvalue = (node) klist.item(0);                  system.out.println("node value:"+kvalue.getnodevalue());             }          }

what gettagvalue() ?

anyway, best tutorial (how read xml file in java) dom parser in java me. have @ this

here gettagvalue() link

private static string gettagvalue(string stag, element eelement){     nodelist nllist= eelement.getelementsbytagname(stag).item(0).getchildnodes();     node nvalue = (node) nllist.item(0);       return nvalue.getnodevalue();     }

javascript - Enclosure Memory Copies -

-
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...

php - Replacing tags in braces, even nested tags, with regex -

-
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."
