ruby - Inline DTD with Builder -

-

how create this...

<!doctype root-element[   <!entity % w3centities public   "-//w3c//entities combined set//en//xml"   "w3centities.ent"   >   %w3centities; ]>

...using builder?

i can manage everying apart "%w3centities;" in second last line following code:

xml.declare! :doctype, "root-element"    xml.declare! :entity, "%", :w3entities, :public,       "-//w3c//entities combined set//en//xml",      "w3centities.ent" end

thanks

here's did work...

xml.target! << "<!doctype root-element[     <!entity % w3centities public     \"-//w3c//entities combined set//en//xml\"     \"w3centities.ent\"     >     %w3centities;   ]>"

is necessary this: /** * ... * * @return void */ i have quite few methods don't have return value, , seems redundant put in comment. considered bad form leave out? if makes clear documentation, leave in, isn't strictly necessary. it's entirely subjective decision. personally, leave out. edit stand corrected. after little googling, wikipedia page says: @return [type description] tag should not used constructors or methods defined void return type. the phpdoc.org website says: @return datatype description @return datatype1|datatype2 description the @return tag used document return value of functions or methods. @returns alias @return support tag formats of other automatic documentors the datatype should valid php type (int, string, bool, etc), class name type of object returned, or "mixed". if want explicitly show multiple possible return types, list them pipe-delimited without spaces (e.g. "@retur...

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...
