特定标签值的 NSXMLParsing

问题描述

我有一个如下所示的 XML 文件:

I have an XML file that looks like this:

 <country>
            <routes>
                <SourceCountry>Ireland</SourceCountry>
                <SourcePort>Larne</SourcePort>
                <DestinationCountry>UK</DestinationCountry>
                <DestinationPort>Troon </DestinationPort>
                        </routes>
            <routes>
                <SourceCountry>Ireland</SourceCountry>
                <SourcePort>Larne</SourcePort>
                <DestinationCountry>UK</DestinationCountry>
                <DestinationPort>Cairnryan </DestinationPort>
                        </routes>
            <routes>
                <SourceCountry>Ireland</SourceCountry>
                <SourcePort>Belfast</SourcePort>
                <DestinationCountry>UK</DestinationCountry>
                <DestinationPort>Birkenhead </DestinationPort>
                        </routes>
            <routes>
                <SourceCountry>Ireland</SourceCountry>
                <SourcePort>Belfast</SourcePort>
                <DestinationCountry>Belgium</DestinationCountry>
                <DestinationPort>Heysham </DestinationPort>
                        </routes>
            <routes>
                <SourceCountry>Belgium</SourceCountry>
                <SourcePort>Warrenpoint</SourcePort>
                <DestinationCountry>UK</DestinationCountry>
                <DestinationPort>Heysham </DestinationPort>
                        </routes>

我想解析 的特定数据；== 爱尔兰和 <DestinationCountry>==英国.我该怎么做?

I want parse particular data for <SourceCountry> == Ireland and <DestinationCountry> == UK. How can I do this?

推荐答案

使用 NSXMLParser

1. 为这个类实现委托...

为这个解析器实现方法...

implement the methods for this parser...

您将需要以下方法..

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURIqualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string

您可以阅读本教程;使用起来很简单.

You can read this tutorial; it is simple to use.
