如何使用NSXMLParser解析包含&符号的字符串？ [英] How to parse strings containing ampersands with NSXMLParser?

问题描述

输入字符串是

<path>a &amp; b</path>

我的Objective C解析器代码是

and my Objective C parser code is

- (void) parser:(NSXMLParser *)parser
foundCharacters:(NSString *)string {
    ...
    if(parserState==EXPECT_PATH) {
        NSLog(@"got %@", string);
    }
    ...
}

这打印得到而不是得到了& amp; amp; b

推荐答案

解析器：foundCharacters：可以多次调用一个元素的内容。您有责任将方法的多次运行中的所有字符附加到一个字符串。

parser:foundCharacters: can be called multiple times for one element's contents. It is your responsibility to append all characters from multiple runs of the method to one string.

所以除非你能确认解析器：foundCharacters：在第一次运行后没有再次调用，这是预期的行为。

So unless you can confirm that parser:foundCharacters: doesn't get called again right after the first run, this is expected behavior.
