TBXML将复杂的xml解析为数组

Question

我有一个xml响应,我需要设置为一个数组.问题是我需要访问每个元素并将其存储在一个数组中,以便我可以将它用于tableview.

<?xml version="1.0" encoding="UTF-8"?>
<Response xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://schema.2sms.com/2.0/schema/0310_ResponseReportStandard.xsd" Version="1.0">

我已经初始化了TBXML对象但无法弄清楚如何获取任何重复信息,我知道它需要某种循环,但我对objective-c很新,所以它证明了一个挑战.

我需要<destination> , <status>, <datesent>, <message>从xml中获取.最多可以有25条记录......

希望有人能帮助我一整天都在努力!

我最近做了类似的事情,你可以快速适应,我的XML是:

<?xml version="1.0" encoding="ISO-8859-1"?>
<agencies>
    <agency>
        <name>Agency 1 name</name>
        <addressFirstLine>Immeuble XYZ<addressFirstLine>
        <addressSecondLine>rue de la republique</addressSecondLine>
        <addressThirdLine>69007 Lyon</addressThirdLine>
        <telNumber>01 23 45 67 89</telNumber>
    </agency>
    <agency>
        <name>Agency 2 name</name>
        <addressFirstLine>Immeuble ABC<addressFirstLine>
        <addressSecondLine>rue de la republique</addressSecondLine>
        <addressThirdLine>69007 Lyon</addressThirdLine>
        <telNumber>01 23 45 67 89</telNumber>
    </agency>
</agencies>

我用来解析这个代码(在我的NSArray调用中得到结果agencies):

    TBXML *tbxml = [[TBXML tbxmlWithXMLFile:yourXmlFile retain];
    TBXMLElement *rootXMLElement = tbxml.rootXMLElement;

    if (rootXMLElement) {
        self.agencies = [self traverseElement:rootXMLElement];
        [delegate managerDidReceiveData];
    }

    // release resources
    [tbxml release];

我在数组转换的功能:

- (NSArray *)traverseElement:(TBXMLElement *)element {

    NSMutableArray *tmpAgencies = [[NSMutableArray alloc] init];

    TBXMLElement *agenciesXmlElement = element->firstChild;
    TBXMLElement *agencyXmlElement;

    do {

        // if the element has child elements, process them
        if ((agencyXmlElement = agenciesXmlElement->firstChild)) {

            NSMutableDictionary *tmpAgency = [[NSMutableDictionary alloc] init];

            do {
                [tmpAgency setValue:[TBXML textForElement:agencyXmlElement] forKey:[TBXML elementName:agencyXmlElement]];

            // Obtain next sibling element
            } while ((agencyXmlElement = agencyXmlElement->nextSibling));

            [tmpAgencies addObject:tmpAgency];
            [tmpAgency release];
        }

    // Obtain next sibling element
    } while ((agenciesXmlElement = agenciesXmlElement->nextSibling));

    return tmpAgencies;
}

这个函数会返回一个数组,其中包含NSDictionary代表你的对象Records.NSDictionary很容易使用,以获得您使用的属性[yourDictionary objectForKey:yourXmlNode].文档在这里:NSDictionary.
