    <p>I am trying to parse XML using NSXMLParser but since some of the xml that I have contains line breaks () I am getting inaccurate parsing. For example "A genuine leader is not a&lt;br&gt; searcher for consensus&lt;br&gt;but, a molder of consensus" gets parsed as "a molder of consensus" Not only does the <br> tags mess it up but also the comma after but seems to mess it up, guessing its because of directly next to the br tag without a space. Anyone have experience on how to fix this? A lot of people hon Stackoverflow seem to have the same issue but I haven't been able to find a solution for iOS. </p> <p>In the xml the br tags prints out like this:</p> <pre><code>&amp;lt;br&amp;gt; </code></pre> <p>This is the xml I am parsing</p> <pre><code>&lt;entry&gt; &lt;title&gt;Quote&lt;/title&gt; &lt;content&gt;A genuine leader is not a&amp;lt;br&amp;gt; searcher for consensus&amp;lt;br&amp;gt; but, a molder of consensus&lt;/content&gt; &lt;/entry&gt; </code></pre> <p>This is my xml parsing code</p> <pre><code>- (void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict { if ([elementname isEqualToString:@"entry"]) { currentQuote = [[SQuote alloc] init]; } } - (void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementname isEqualToString:@"content"]){ currentQuote.content = currentNodeContent; } if ([elementname isEqualToString:@"entry"]) { [self.popularEntries addObject:currentQuote]; currentQuote = nil; currentNodeContent = nil; } } </code></pre> <p><strong>EDIT:</strong></p> <p>I tried changing my charactersFound code to the following :</p> <pre><code>- (void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if (currentNodeContent == nil) currentNodeContent = [[NSMutableString alloc] initWithCapacity: 20]; [currentNodeContent appendString: [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; } </code></pre> <p>But I am still getting an error that says "Attempt to mutate immutable object with appendString:" even though currentNodeContent is of type NSMutableString</p>

    2. COThanks @DonRoby but I am still unable to figure it out. I changed my foundCharacters code to if (currentNodeContent == nil) currentNodeContent = [[NSMutableString alloc] initWithCapacity: 20]; else{ [currentNodeContent appendString: [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; } but I am getting an error saying "Attempt to mutate immutable object with appendString:" Do you know how to fix that?

    3. COIt will be better if you update the code in your question rather than trying to put code in a comment. I know xml parsing pretty well, so I was able to see that was related, but I don't know this language, so you might get more help from someone who does both.

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.
