iphone - Issue with Xml parsing Using Regex -

here xml received via webservice..

<?xml version="1.0" encoding="utf-8"?> <quotes xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xsd="http://www.w3.org/2001/xmlschema" xmlns="http://swanandmokashi.com">   <quoteoftheday>hit user continue.</quoteoftheday>   <author>fuzzel fish administration page</author> </quotes> 

and im trying parse in connectiondidfinishloading: ...

{              webdata_str=[[nsstring alloc]initwithdata:webdata encoding:nsutf8stringencoding];  nsstring *pattern = @"<quoteoftheday>(.*)</quoteoftheday><author>(.*)</author>";  nsregularexpression *regex = [nsregularexpression regularexpressionwithpattern:pattern                         options:nsregularexpressioncaseinsensitive                                                                            error:nil];  __block nsstring *quotestring,*author= nil;  [regex enumeratematchesinstring:webdata_str options:0 range:nsmakerange(0, [webdata_str length]) usingblock:^(nstextcheckingresult *match, nsmatchingflags flags, bool *stop) {     // not executing...      if (0 < [match numberofranges]) {         nsrange range = [match rangeatindex:1];         quotestring = [webdata_str substringwithrange:range];           nsrange range1 = [match rangeatindex:2];         author = [webdata_str substringwithrange:range1];              } }];          final=[nsstring stringwithformat:@"\n%@\n%@",quotestring,author]; nslog(@"final--- %@",final); } 

what's wrong in this? , execution flow not going inside block..

a better solution use xml parser (e.g. nsxmlparser) instead of regular expressions.

but answer concrete problem: regex not match whitespace (newline , spaces) between </quoteoftheday> , <author>. if change pattern to

nsstring *pattern = @"<quoteoftheday>(.*)</quoteoftheday>\\s*<author>(.*)</author>"; 

you expected output.
