c# - find xaml text with regular expression -

-

how find textblocks in xaml files contains style parameter using search in microsoft visual studio. there regexp possible used here? here example of block:

<textblock text="{binding localizedresources.boom, source={staticresource localizedstrings}}"         foreground="{staticresource gray}"         textwrapping="wrap"         style="{staticresource sdfsdf}"         horizontalalignment="center"         visibility="{binding erroroccured,converter={staticresource tovisibilityconverter},converterparameter=true}"/>

thanks.

since you're in editor, usual warnings using regex parse xml can relaxed (only bit)...

this work:

(?s)<textblock(?:(?!/>).)*?\bstyle=.*?/>

see demo.

  • the trick make sure don't past closing tag , end matching more text want.
  • if there nested <tags>, fail

explanation

  • (?s) activates dotall mode, allowing dot match across lines
  • <textblock matches literal characters
  • the non-capturing group (?:(?!/>).) matches 1 character, long not followed /> (this avoid jumping out of present tag)
  • *? allows type of character mentioned mach lazily, 0 or more times, to...
  • \bstyle= literal style=, \b on left ensure style not embedded in mystyle
  • .*? lazily matches characters to...
  • the closing />

php - Changing the visibility scope of parent methods in child classes -

-
i've got validator class , uservalidator class extends it. my validator has public method setrule(...) public visibility. when extend want change visibility of setrule(...) parent method private/protected within child it's visible child , no outsiders can call method from child. is possible? if so, how achieve it? from architectural point of view not recommended. stated in comments clean way set method protected children can access it. i cannot think of single use case put me in need call public method on parent class not allowed call on child class. that's against open/closed principle. classes should open extension, not modification. since not question i'll provide way how can achieved though. note: this method makes use of class responsible instantiation it's hack. solution not make use of php's native language features when throwing accessibility errors. first let's define classes had <?php class validator { ...
