如何使imageURL脱离HTML

Question

我需要从URL中删除HTML标记，这是我从服务器的响应中得到的。

我试过遵循代码，但这对我没有帮助。有什么主意吗？我得到的那根绳子

“图像的测试讨论

“

我添加了扩展来检索HTTP字符串，但是我没有得到准确的URL。

extension String {

       func removeHTMLTag() -> String {

           return self.replacingOccurrences(of: "<[^>]+>", with: "", options: String.CompareOptions.regularExpression, range: nil)

        }
}

Answer 1

使用SwiftSoup，您可以获得imageURL

let doc = try SwiftSoup.parse("<div id=div2><p>How are you?</p><div id=div3><img src=http://example.com/test.png></div></div>");
for element in try doc.select("img").array(){
    try print(element.attr("src"))
}
**Output**
//http://example.com/test.png

Answer 2

你可以试试这个。

 func removeHTMLTags(for regex: String!, in text: String!) -> [String] {
    do {
        let regex = try NSRegularExpression(pattern: regex, options: [])
        let nsString = text as NSString
        let results = regex.matches(in: text, range: NSMakeRange(0, nsString.length))
        return results.map { nsString.substring(with: $0.range)}
    } catch let error as NSError {
        print("invalid regex: \(error.localizedDescription)")
        return []
    }
}

把这个函数叫做-

let text = "test Discussion for images<div><img src=\"http:\\\\45.35.4.250\\MvestUploadContainer\\7e3ba5ba-000b-4dc4-ae6e-a4bc8d59088c.png\"><br></div>"
let url = removeHTMLTags(for: "(http[^\\s]+(jpg|jpeg|png)\\b)", in: String(text))
print(url[0])

输出- http:\\45.35.4.250\MvestUploadContainer\7e3ba5ba-000b-4dc4-ae6e-a4bc8d59088c.png
