php - cast simplexmlelement to string to get inner content but keep htmlspecialchars escaped -


i have xmlfile:

$xml = <<<eod <?xml version="1.0" encoding="utf-8"?> <metadata xmlns="http://www.test.com/" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="test"> <qkc6b1hh0k9>testdata&amp;more</qkc6b1hh0k9> </metadata> eod;

now loaded simplexmlobject , later on wanted inner of "qkc6b1hh0k9"-node

$xmlrootelem = simplexml_load_string( $xml ); $xmlrootelem->registerxpathnamespace( 'xmlns', "http://www.test.com/" );  // ...  $xpathelems = $xmlrootelem->xpath( './'."xmlns:qkc6b1hh0k9" ); $var = (string)($xpathelems[0]); var_dump($var);

i expected string 

testdata&amp;more

... got

testdata&more
  • why __tostring() method of simplexmlobject converting escaped specialchars normal chars? can deactivate behaviour?

  • i came temp-solution, consider dirty, say?

    (strip_tags($xpathelems[0]->asxml()))

  • may domdocument alternative?

thanks on questions!

edit

problem solved, problem not in __tostring method of simplexml, later on when using string addchild

the behaviour described above totaly fine , has expected can see in answers...

problems came up, when value added xml-document via "addchild". since addchild doesn't escape ampersand (http://www.php.net/manual/de/simplexmlelement.addchild.php#103587) 1 has manually.

if create xml tag, sane method, , set contain string "testdata&more", escaped testdata&amp;more. therefore logical extracting string content out reverses escaping procedure give text put in.

the question is, why want xml-escaped representation? if want content of element intended author, __tostring() doing right thing; there more 1 way of representing string in xml, data being represented should care about.

if reason need details of how xml constructed in particular instance, use more complex parsing framework such dom, separate testdata&amp;more text node (containing "testdata"), entity node (with name "amp"), , text node (containing "more").

if, on other hand, want put xml (or html) document, let simplexml unescaping properly, , re-escape @ appropriate time.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
