    <p>I have dynamic string that currentString. For example currentstring like :</p> <pre><code>&lt;html&gt;&lt;head&gt;&lt;title&gt;&lt;/title&gt;&lt;meta content="width=320.000000, initial-scale=0.47, maximum-scale=1.0, user-scalable=1" name="viewport"&gt;&lt;/head&gt;&lt;body&gt;&lt;table width="510" cellpadding="0" cellpadding="0"&gt;&lt;tr&gt;&lt;td valign="top"&gt;&lt;p&gt;&lt;a href="http://erhandemirci.blogspot.com/masak-in-baskani-neden-gorevden-alindi-haberi-828402.html"&gt;&lt;img src="http://erhandemirci.blogspot.com/images//news/r-farukeliedioglu-300200-828402.jpg" width="72" height="48" style="border: 1px #000000 solid;" hspace="2" align="left"&gt;&lt;/a&gt;content...........&lt;/p&gt; &lt;p&gt; &lt;/p&gt; &lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/body&gt;&lt;/html&gt; </code></pre> <p>I want to change table tag's width from 510 to 0. I tried following code but it's not working . </p> <pre><code>NSString *currentString = @"&lt;html&gt;&lt;...width &gt; &lt;table width="" .... &gt; dynamic string"; // Regular expression to find "word characters" enclosed by {...}: NSRegularExpression *regex; regex = [NSRegularExpression regularExpressionWithPattern:@"\\table width=\"(\\w+)\\\"" options:0 error:NULL]; NSMutableString *modifiedString = [currentString mutableCopy]; __block int offset = 0; [regex enumerateMatchesInString:currentString options:0 range:NSMakeRange(0, [currentString length]) usingBlock:^(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop) { // range = location of the regex capture group "(\\w+)" in currentString: NSRange range = [result rangeAtIndex:1]; // Adjust location for modifiedString: range.location += offset; // Get old word: NSString *oldWord = [modifiedString substringWithRange:range]; // Compute new word: // In your case, that would be // NSString *newWord = [self replaceWord:oldWord]; NSString *newWord =@"0"; // Replace new word in modifiedString: [modifiedString replaceCharactersInRange:range withString:newWord]; // Update offset: offset += [newWord length] - [oldWord length]; } ]; NSLog(@"modified%@", modifiedString); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
