XMLModelizer

XMLModelizer 是一个简单的 XML 解析器和模型化器。
一旦您将模型类和 XML URL 传递给 XMLModelizer，您就可以获取包含您需要的 XML 元素模型实例。

示例

如果您想获取以下 xml 中每个 item 标签的 title、link、content:media、category 和 pubDate 值。

<rss xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:media="http://search.yahoo.com/mrss/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:nyt="http://www.nytimes.com/namespaces/rss/2.0" version="2.0">

                The apparent plan by the Chinese president has unsettled the party elite and created uncertainty over whether Mr. Xi will try to stay in power beyond the usual two terms.

首先，定义您自定义的模型，继承自 XMLModelizerModel 并重写 xmlModelizerXpathKeyMap 函数，添加您想要的属性。

import XMLModelizer

class NYTimesArticle: XMLModelizerModel {

    //Add properties you want to get from xml.
    var title: [String]! // please define properties as [String]!
    var link: [String]!
    var media: [String]!
    var category: [String]!
    var pubDate: [String]!

    //Please define xpath to get contents of xml.
    //In dictionary, key is your property, and value is xpath of its key.
    // [property : xpath]
    override class func xmlModelizerXpathKeyMap() -> [String:String] {
        return [
            "title":"//item/title",
            "link":"//item/link",
            "media":"//item/media:content/@url",
            "category":"//item/category",
            "pubDate":"//item/pubDate",
        ]
    }
}

最后，您可以通过以下方式获取 Array<NYTimesArticle>

import XMLModelizer
// open static func modelize(modelClass: XMLModelizerModel.Type, urlString: String) -> [AnyObject]
let nytimesArticles: Array<NYTimesArticle> = XMLModelizer.modelize(NYTimesArticle.self, "http://rss.nytimes.com/services/xml/rss/nyt/World.xml")

let article: NYTimesArticle = nytimesArticles.first
print(article.title.first) // "Xi Jinping May Delay Picking China’s Next Leader, Stoking Speculation"
print(article.category[1])// "Communist Party of China"

注意

如果在 Xcode8 中您收到错误 “Use Legacy Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.，请将 XMLModelizer 的 plist 中的“Use Legacy Swift Language Version” 设置为否在您的 Pods 项目中。

要求

iOS 8.0 或更高版本。

安装

XMLModelizer 通过 CocoaPods 提供。要安装它，只需将以下行添加到您的 Podfile

pod "XMLModelizer"
