ruby - Parsing HTML from a defined start point to a defined end point? -

-

i have html: 

<hr noshade> <p><a href="#1">some text here</a></p> <p style="margin-top:0pt;margin-bottom:0pt;line-height:120%;"><span style="color:#000000;font-weight:bold;">this description</span></p> <hr noshade> <!-- <hr noshade> delimiter me --> <p><a href="#2">some more text here</a></p> <p style="margin-top:0pt;margin-bottom:0pt;line-height:120%;"><span style="color:#000000;font-weight:bold;">this description more text</span></p> <hr noshade>

while parsing using nokogiri, want print information between each of these set of tags separated own delimiter <hr noshade>. so, first block should print information between "p" tags lie between 2 hr noshade tags , on.

i'm using accepted answer on xpath select elements between 2 specific elements

i have semi-safisfactory solution

you can use xpath expression:

.//hr[1][@noshade]   /following-sibling::*[not(self::hr[@noshade])]                        [count(preceding-sibling::hr[@noshade])=1]

for first group between <hr noshade> 1 , 2,

then,

.//hr[2][@noshade]   /following-sibling::*[not(self::hr[@noshade])]                        [count(preceding-sibling::hr[@noshade])=2]

for elements between <hr noshade> 2 , 3, etc.

what these expressions select:

  1. all siblings of <hr noshade>, specified position n
  2. that have n <hr noshade> previous siblings, i.e. positionned in n'th group
  3. and not <hr noshade> themselves

as select several elements between 2 <hr noshade>, may have loop on results , extract data each sibling element.

anyone on more generic solution?

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
