Question

嗨，我在过去的两天到处都看过＆amp;找不到对我有用的东西。我已经设法从网址中提取数据，并在我的日志中显示每个元素和值。

我无法弄清楚的步骤是如何将它添加到我的“events”数组中，而不必手动搜索每个字符串，因为它会自动为我执行（如我的日志中所示）。

这是我的loadUrl方法：

- (void)loadURL {

// Create a success block to be called when the asyn request completes
TBXMLSuccessBlock successBlock = ^(TBXML *tbxmlDocument) {
    NSLog(@"PROCESSING ASYNC CALLBACK");

    // If TBXML found a root node, process element and iterate all children
    if (tbxmlDocument.rootXMLElement)
        [self traverseElement:tbxmlDocument.rootXMLElement];

};

// Create a failure block that gets called if something goes wrong
TBXMLFailureBlock failureBlock = ^(TBXML *tbxmlDocument, NSError * error) {
    NSLog(@"Error! %@ %@", [error localizedDescription], [error userInfo]);
};

// Initialize TBXML with the URL of an XML doc. TBXML asynchronously loads and parses the file.
tbxml = [[TBXML alloc] initWithURL:[NSURL URLWithString:@"http://somexml.com/xml"] 
                           success:successBlock 
                           failure:failureBlock]; 

    events = [NSMutableArray array]; }

这是我的traverseElement方法：

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

do {
    // Display the name of the element
    NSLog(@"%@",[TBXML elementName:element]);


    // iterate all child elements of tbxml.rootXMLElement that are named "author"
    [TBXML iterateAttributesOfElement:element withBlock:^(TBXMLAttribute *attribute, NSString *name, NSString *value) {

        // Display name and value of attribute to the log window
        NSLog(@"%@->%@ = %@",[TBXML elementName:element], name, value);

    }];

    // if the element has child elements, process them
    if (element->firstChild) [self traverseElement:element->firstChild];

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


}

这是我要拉的xml：

<resultsPage totalEntries="6" perPage="50" page="1" status="ok">
<results>
<event uri="http://somexml.com/xml" popularity="0.863682" displayName="Radio 1's Hackney 
Weekend 2012" id="9234656" type="Festival" status="ok">
<location city="London, UK" lng="-0.128" lat="51.5078"/>
<series displayName="Radio 1's Hackney Weekend"/>
<end time="" date="2012-06-24" datetime=""/>
<start time="" date="2012-06-23" datetime=""/>
<performance displayName="Lucy Labeaux" billingIndex="5" id="23336188" billing="headline">
<artist uri="http://www.somexml.com/artistxml" displayName="Lucy Labeaux" id="1168415">
<identifier href="http://somexml.com.xml" mbid="4593d49a-7f67-46ba-9ec0-126bd676286f"/>
</artist>
</performance>

我的日志如下所示：

PROCESSING ASYNC CALLBACK
 resultsPage
 resultsPage->totalEntries = 6
 resultsPage->perPage = 50
 resultsPage->page = 1
 resultsPage->status = ok
 results
 event
 event->uri = http://example.com
 event->popularity = 0.863682
 event->displayName = Cooled Up Week 2012
 event->id = 9234656
 event->type = Festival
 event->status = ok
 location
 location->city = London, UK
 location->lng = -0.128
 location->lat = 51.5078
 series
 series->displayName = Cooled Up Week 2012
 end
 end->time = 
 end->date = 2012-06-24
 end->datetime = 
 start
 start->time = 
 start->date = 2012-06-23
 start->datetime = 
 performance
 performance->displayName = Lucy Labeaux
 performance->billingIndex = 1

现在我已经浏览了所有元素，属性等，如何将其链接到我的表视图和行计数？我想放弃，请帮忙！非常感谢你的时间非常感谢你！

Sudo rm -rf得到了最好的回应

那你为什么不试试呢？我用过TBXML已经有一段时间了。从那以后，我开始直接使用libxml2（通过Cocoa包装器），所以我可以使用X-path直接选择我想要的东西而不需要循环。作为替代方案，您应该尝试使用此解析库;我听说它的简洁性很棒。 github.com/ZaBlanc/RaptureXML对不起，我现在没有时间为此编写测试用例。

不太清楚如何将TBXML url数据添加到我的表视图中
