  1. PONSXML Parsing Ampersand Character Causes Shut Down
    text
    copied!<p>I am parsing a simple XML file, however sometimes there are tags that contain ampersands (&amp;) in the node. I've done some research <a href="https://stackoverflow.com/questions/7838708/how-to-parse-strings-containing-ampersands-with-nsxmlparser">here</a> and <a href="https://stackoverflow.com/questions/7291534/nsxmlparser-problem-with-ampersand-character">here</a> but the problem is persisting. The problem is that the parser simply stops when it encounters the offending XML element. The XML looks like this: </p> <pre><code>&lt;video&gt; &lt;video_id&gt;42&lt;/video_id&gt; &lt;video_header&gt;Six &amp; Eight&lt;/video_header&gt; &lt;video_subheader&gt;So Long&lt;/video_subheader&gt; &lt;/video&gt; </code></pre> <p>The parser is updating an object, called <code>DisStep</code>, that has a <code>parsedVideoArray</code> attribute. The attribute is just an array of <code>Parsed_Video</code> objects. So the problem would be that when the the parser gets to <code>foundCharacters</code> for the element <code>video_header</code> it will not continue to <code>didEndElement</code>. In fact, an <code>NSLog</code> in the foundCharacters method of <code>currentNodeContent</code> is just <code>"Six "</code>.</p> <p>And here is the code for the parser. All it does is look for videos and gather info about them.</p> <pre><code>-(void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict { if ([elementName isEqualToString:@"video"]) { videoBeingParsed = [[Parsed_Video alloc] init]; } } -(void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { string = [string stringByReplacingOccurrencesOfString:@"&amp;" withString:@"&amp;amp;"]; currentNodeContent = (NSMutableString *) string; } - (void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:@"video_id"]) { videoBeingParsed.Video_ID = currentNodeContent; currentNodeContent = nil; } else if ([elementName isEqualToString:@"video_header"]) { videoBeingParsed.Video_Header = currentNodeContent; currentNodeContent = nil; } else if ([elementName isEqualToString:@"video_subheader"]) { videoBeingParsed.Video_SubHeader = currentNodeContent; currentNodeContent = nil; } else if ([elementName isEqualToString:@"video"]) { [DisStep.parsedVideoArray addObject:videoBeingParsed]; currentNodeContent = nil; videoBeingParsed = nil; } } @end </code></pre> <p>I tried the <code>stringByReplacingOccurrencesOfString: withString:</code> but the parser still stops working. Is there a way around this other than changing the XML?</p>
