ruby on rails - Extra <to_s/> when using builder to generate XML -

-

i'm trying generate kml using builder. know options out there doing 2.2 specific things aren't supported kml gems i've looked @ , able accomplish leveraging xml framework.

i tag @ end of file when rendering kml/xml. suspect i'm missing basic setting builder object or how i'm rendering output it. here's simple example demonstrates issue:

def kml2dot2   @site = site.find(params[:id])   xml = builder::xmlmarkup.new(:indent => 2)   xml.instruct!   xml.kml("xmlns" => "http://www.opengis.net/kml/2.2") {     xml.placemark       xml.name @site.mapnamefull       xml.point         xml.coordinates @site.lat.to_s + "," + @site.lng.to_s + ",0"       end     end   }   render :text => xml, :type=>"text/kml"  end

produces:

<?xml version="1.0" encoding="utf-8"?> <kml xmlns="http://www.opengis.net/kml/2.2">   <placemark>     <name>seattle city hall</name>     <point>       <coordinates>47.6040746,-122.33005,0</coordinates>     </point>   </placemark> </kml> <to_s/>

i'm trying understand how avoid <to_s/> being included , i'm doing wrong builder. insight.

you don't need initialize xml builder object. use integrated builder template handler.

  1. call template kml2dot2.xml.builder
  2. write code directly in view

example

def kml2dot2   @site = site.find(params[:id]) end  # kml2dot2.xml.builder xml.kml("xmlns" => "http:// www.opengis.net/kml/2.2")   xml.placemark     xml.name @site.mapnamefull     xml.point        xml.coordinates "#{@site.lat},#{@site.lng},0"     end   end end

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...

-
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."
