使用TBXMLParser的属性值

Question

我必须解析相对大量的XML数据，因此我使用TBXMLParser。我对它还是个新手。下面是示例XML格式。

<item>
<title> Test XML</title>
<link>http://www.google.com</link>
<media:content url="http://blog.directorymaximizer.com/wp-content/uploads/2012/09/google.jpg" medium="image">
    <media:title type="html”>Google</media:title>
</media:content>

<media:content url="http://icons.iconarchive.com/icons/fasticon/web-2/256/Google-icon.png" medium="image">
    <media:title type="html”>Google-Png</media:title>
</media:content>

<media:content url="http://icons.iconarchive.com/icons/fasticon/web-2/256/Google-icon.png" medium="image">
<media:title type="html”>Google-Png</media:title>
</media:content>
</item>


and it goes on...

我想要获取第二个url =‘必须...’的值。

TBXMLElement *iconElement = [TBXML childElementNamed:@"Image" parentElement:element];
strIcon = [TBXML valueOfAttributeNamed:@"url" forElement:iconElement];

这是代码，我试过了。使用它，我能够获得第一个url属性值。任何建议都将不胜感激。谢谢您:)

Answer 1

获取第二个节点的值..根据您编辑的样本数据..

TBXML *tbxml = [TBXML tbxmlWithURL:[NSURL URLWithString:yourXMLString]];  //replace yuorXMLString with your string
TBXMLElement * root = tbxml.rootXMLElement;

// if root element is valid


if (root != nil) {
    TBXMLElement * element = [TBXML childElementNamed:@"item" parentElement:root];

         TBXMLElement *node= [TBXML childElementNamed:@"media:content" parentElement:element];
          TBXMLElement *secondNode= [TBXML nextSiblingNamed:@"media:content" searchFromElement:node];
        NSLog(@"the second url name is : %@",[TBXML valueOfAttributeNamed:@"url" forElement:secondNode]);

}

Answer 2

TBXML *tbxml = [TBXML tbxmlWithURL:[NSURL URLWithString:yourXMLString]];  //replace yuorXMLString with your string

    TBXMLElement * root = tbxml.rootXMLElement;

    // if root element is valid
    if (root!=nil) {

        TBXMLElement * element = [TBXML childElementNamed:@"item" parentElement:root];

        while (element != nil) {
TBXMLElement *iconElement = [TBXML childElementNamed:@"Image" parentElement:element];
strIcon = [TBXML valueOfAttributeNamed:@"url" forElement:iconElement];

    }
}

希望这能起作用？？
