c# - Convert a Flowdocument to XML and XML to Flowdocument -


i use code here(answer wiimax) convert flowdocument xml , convert flowdocument. have problems here.

my code convert:

public static bool isflowdocument(this string xamlstring)         {             if (xamlstring == null || xamlstring == "")                 throw new argumentnullexception();              if (xamlstring.startswith("<") && xamlstring.endswith(">"))             {                 xmldocument xml = new xmldocument();                 try                 {                     xml.loadxml(string.format("<root>{0}</root>", xamlstring));                     return true;                 }                 catch (xmlexception)                 {                     return false;                 }             }             return false;         }          public static flowdocument toflowdocument(this string xamlstring)         {             if (isflowdocument(xamlstring))             {                 var stringreader = new stringreader(xamlstring);                 var xmlreader = system.xml.xmlreader.create(stringreader);                  return xamlreader.load(xmlreader) flowdocument;             }             else             {                 paragraph myparagraph = new paragraph();                 myparagraph.inlines.add(new run(xamlstring));                 flowdocument myflowdocument = new flowdocument();                 myflowdocument.blocks.add(myparagraph);                  return myflowdocument;             }         }

i enter code(as example, not code, use in program):

my code

and after convert code:

my code

you see blank skipped. , after namespace there add { } looked @ converted xml string, there no blank skipped, { } to

do know how fix or see fail me?

curly braces:

this because of binding-syntax , wpf (xamlreader , xamlwriter) wants ;).

when in xaml-code like

<run text="{" />

the xaml-engine first assumes binding. since there no , depending on how create flowdocument '{' escaped '{}{'

one workaround is, put curly brace this:

<run>{</run>

another workaround avoid curly brace first character:

<run text=" {" />

spaces: there attribute comes in handy:

<run xml:space="preserve">some                   space</run>

this isn't xaml xml attribute handled xaml-engine.

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
