特性

构建 XML/HTML 树并进行导航。
支持 XPath 查询。
全面的单元测试覆盖。
支持 Swift Package Manager (SPM)。兼容 Linux。

要求

iOS 8.0+ / Mac OS X 10.9+ / watchOS 2.0+ / tvOS 9.0+
Xcode 8.0+

安装

CocoaPods

要使用 CocoaPods 将 Ji 集成到您的 Xcode 项目中，请在您的 Podfile 中指定它

use_frameworks!

pod 'Ji', '~> 5.0.0'

然后，运行以下命令

$ pod install

Carthage

要使用 Carthage 将 Ji 集成到您的 Xcode 项目中，请在您的 Cartfile 中指定它

github "honghaoz/Ji" ~> 5.0.0

Swift Package Manager (SPM)

先决条件

brew install libxml2
brew link --force libxml2

Linux

$ sudo apt-get install libxml2-dev

更新 `Package.swift`

要在您的项目中集成 Ji，请将正确的描述添加到您的 Package.swift 文件

// swift-tools-version:5.0
import PackageDescription

let package = Package(
    name: "YOUR_PROJECT_NAME",
    dependencies: [
        .package(url: "https://github.com/honghaoz/Ji.git", from: "5.0.0")
    ],
    targets: [
        .target(
            name: "YOUR_TARGET_NAME",
            dependencies: ["Ji"]
        ),
        ...
    ]
)

手动

如果您不想使用依赖管理器，您可以手动将 Ji 集成到您的项目中。

将源文件添加到您的项目中
- 将 Sources/Ji 文件夹中的 Ji.swift、JiHelper.swift 和 JiNode.swift 拖到您的项目中。
- 将 Sources/Clibxml2 文件夹拖到您的项目中。
配置您的项目
- 打开项目，选择目标，在Build Settings（构建设置）下，在 Header Search Paths（头文件搜索路径）中，添加 $(SDKROOT)/usr/include/libxml2
- 在Build Settings（构建设置）下，在 Import Paths（导入路径）中，添加 $(SRCROOT)/Clibxml2（确保这是 Clibxml2 文件夹的路径）

用法

如果您使用 CocoaPods 来集成 Ji。首先导入 Ji
import Ji

使用 URL 初始化

let jiDoc = Ji(htmlURL: URL(string: "http://www.apple.com/support")!)
let titleNode = jiDoc?.xPath("//head/title")?.first
print("title: \(String(describing: titleNode?.content))") // title: Optional("Official Apple Support")

使用 String 初始化

let xmlString = "<?xml version='1.0' encoding='UTF-8'?><note><to>Tove</to><from>Jani</from><heading>Reminder</heading><body>Don't forget me this weekend!</body></note>"
let jiDoc = Ji(xmlString: xmlString)
let bodyNode = jiDoc?.rootNode?.firstChildWithName("body")
print("body: \(String(describing: bodyNode?.content))") // body: Optional("Don\'t forget me this weekend!")

使用 Data 初始化

let googleIndexData = try? Data(contentsOf: URL(string: "http://www.google.com")!)
if let googleIndexData = googleIndexData {
    let jiDoc = Ji(htmlData: googleIndexData)!
    let htmlNode = jiDoc.rootNode!
    print("html tagName: \(String(describing: htmlNode.tagName))") // html tagName: Optional("html")

    let aNodes = jiDoc.xPath("//body//a")
    if let firstANode = aNodes?.first {
        print("first a node tagName: \(String(describing: firstANode.name))") // first a node tagName: Optional("a")
        let href = firstANode["href"]
        print("first a node href: \(String(describing: href))") // first a node href: Optional("http://www.google.ca/imghp?hl=en&tab=wi")
    }
} else {
    print("google.com is inaccessible")
}

let 戟文档 = 戟(htmlURL: URL(string: "https://cocoapods.org.cn/pods/Ji")!)
let attribution = 戟文档?.xPath("//ul[@class='attribution']")?.first
print("作者(Author): \(String(describing: attribution?.content))") // 作者(Author): Optional("ByHonghao Zhang")
