How to read an Array of Element Names from XMLSchema XML File in PHP? -


i wanted list of schema elements xml. example

<xs:schema id="spponlinexml" xmlns="" xmlns:xs="http://www.w3.org/2001/xmlschema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">  <xs:element name="spponlinexml" msdata:isdataset="true" msdata:maindatatable="lev_settings" msdata:usecurrentlocale="true">   <xs:complextype>     <xs:choice minoccurs="0" maxoccurs="unbounded">       <xs:element name="lev_settings">         <xs:complextype>           <xs:sequence>             <xs:element name="levid" type="xs:int" minoccurs="0" />             <xs:element name="attheadid" type="xs:int" minoccurs="0" />             <xs:element name="mindatetype" type="xs:unsignedbyte" minoccurs="0" />             <xs:element name="minmonth" type="xs:unsignedbyte" minoccurs="0" />           </xs:sequence>         </xs:complextype>       </xs:element>     </xs:choice>   </xs:complextype>  </xs:element> </xs:schema>

from above schema wanted create array of elements "levid","atthead","mindatetype","minmonth"

to obtain xs:element name-attribute values array suggest pick simplexml , make use of xpath. once you've got xml in string (or file) straight forward if know xpath expressions:

# obtain element names incl. complextypes:  //xs:element/@name  # obtain element names excl. complextypes , #  contain incl. comments, text etc.:  //xs:element[not(node())]/@name

and per php code exmaple looks like:

$xml = simplexml_load_string($string);  echo "obtain element names incl. complextypes:\n";  $elementnames = array_map('strval', $xml->xpath('//xs:element/@name')); print_r($elementnames);  echo "\nobtain element names excl. complextypes ,   contain incl. comments, text etc.:\n";  $elementnames = array_map('strval', $xml->xpath('//xs:element[not(node())]/@name')); print_r($elementnames);

see online demo.

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 ...
