    <p>I'm having a really hard time trying to figure this out and would really appreciate any help.</p> <p>I'm trying to parse a utf 8 string with NSXMLParser but it won't work.</p> <p>here is my string</p> <p><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;&lt;host&gt;&lt;type&gt;mac&lt;/type&gt;&lt;port&gt;62181&lt;/port&gt;&lt;address&gt;192.168.1.159&lt;/address&gt;&lt;hostname&gt;Samuel’s%20Mac%20Book&lt;/hostname&gt;&lt;username&gt;samuelw&lt;/username&gt;&lt;/host&gt;</code></p> <p>and here the parsing code </p> <pre><code>- (void) parse:(NSString*)XMLEncodedString withLength:(int)l_length { #ifndef NDEBUG NSLog(@"Received lookup %@",XMLEncodedString); #endif NSData* data=[XMLEncodedString dataUsingEncoding:NSUTF8StringEncoding]; NSXMLParser *parser = [[NSXMLParser alloc] initWithData:data]; [parser setDelegate:self]; // The parser calls methods in this class [parser setShouldProcessNamespaces:NO]; // We don't care about namespaces [parser setShouldReportNamespacePrefixes:NO]; // [parser setShouldResolveExternalEntities:NO]; // We just want data, no other stuff [parser parse]; // Parse that data.. [parser release]; } </code></pre> <p>the XMLEncodedString is constructed like this </p> <pre><code>- (void) checkForReceive { //NSLog(@"listener: waiting to recvfrom...\n"); addr_len = sizeof their_addr; if ((numbytes = recvfrom(sockfd, buf, MAXBUFLEN-1 , 0, (struct sockaddr *)&amp;their_addr, &amp;addr_len)) == -1) { perror("recvfrom"); return; } buf[numbytes] = '\0'; NSString * string = [[NSString alloc] initWithUTF8String:buf]; [self parse:string withLength:numbytes]; [string release]; } </code></pre> <p>my problem is coming from the Unicode Character 'RIGHT SINGLE QUOTATION MARK' (U+2019) that I have in my string and I am getting this error:</p> <p>2010-07-19 17:13:35.734 SwypeSendForMac2[34354:4233] Error Domain=NSXMLParserErrorDomain Code=73 "The operation couldn’t be completed.

    1. COalthough this has nothing to do with your problem, I wonder what the use of the `withLength` parameter could be, since `NSString` knows it's length, which is not the number of bytes in UTF-8 form, but the number of (Unicode) characters.

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.
