Question

我创建了一个RSS解析器并且效果很好，但是，我对'p'元素有疑问。我的RSS编码的提要有'p'，当我接受它时，它带有它。我该如何删除它？

我想删除它：

<p>

这是我的解析器：

    - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
  namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
    if ([current isEqualToString:@"item"]) [outstring appendFormat:@"%@", @"\n"];
    current = nil;
}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
    if (!current) return;
    if ([current isEqualToString:@"content:encoded"]) [outstring appendFormat:@"%@", string];
}

这是我最后的行动：

_kocTextView.text = @"";

        NSURL *url4 = [NSURL URLWithString:@"http://www.iburc.com/?feed=rss2&cat=7"];

        top10Parser = [[Top10Parser alloc] initWithDelegate: self url: url4];

Answer 1

你试过吗

[stringWhereYouWantToRemoveP stringByReplacingOccurrencesOfString:@"<p>" withString:@""];

Answer 2

改变这个：

if ([current isEqualToString:@"item"]) [outstring appendFormat:@"%@", @"\n"];

为：

if ([current isEqualToString:@"item"]) {
    [outstring replaceOccurrencesOfString:@"<p>" withString:@"" options:0 range:NSMakeRange(0, outstring.length)];
    [outstring replaceOccurrencesOfString:@"</p>" withString:@"" options:0 range:NSMakeRange(0, outstring.length)];

    [outstring appendString:@"\n"];
}

根据您的需要，您可能希望将<p>替换为\n\n而不是空字符串。

从Rss Parser Text中删除“<p>”</p>
