Question

我正在使用以下版本的JSoup（以及Java 1.7）：

<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.11.3</version>
</dependency>

我的代码：

public class HtmlTagUtils {

    private static String mockHtml = "<asset-entity type=\"photo\" id=\"1236ad76-7433-fs34-50d1-b12bdbc308899af\">"
+ "</asset-entity>\r\nAngelie Jolie was seen at Wholefoods with ex-beau Brad Pitt.\r\n <asset-entity type=\"photo\" id=\"2346fe7d-c175-c380-4ab2-dda068b42b033dvf\">"
+ "</asset-entity>\r\n- The majority of their kids were with them.\r\n<asset-entity type=\"video\" id=\"45064086-5d85-1866-4afc-a523c04c2b3e43b6\"> </asset-entity>\r\n";

    public static List<String> extractIdsForPhotos(String html) {
        Document doc = Jsoup.parse(html);
        Elements elements = doc.select("asset-entity[type=photo]");
        List<String> photos = new ArrayList<>();
        for (Element element : elements) {
            String type = element.attributes().get("type");
            String id = element.attributes().get("id");
            photos.add(id);
        }
        return photos;
    } 

    public static List<String> extractIdsForVideos(String html) {
        Document doc = Jsoup.parse(html);
        Elements elements = doc.select("asset-entity[type=video]");
        List<String> videos = new ArrayList<>();
        for (Element element : elements) {
            String type = element.attributes().get("type");
            String id = element.attributes().get("id");
            videos.add(id);
        }
        return videos;
    }

    public static void main (String args []) {
        List<String> photoIds = extractIdsForPhotos(mockHtml);
        for (String photoId : photoIds) {
            System.out.println("\n\tphotoId: " + photoId);
        }

        List<String> videoIds = extractIdsForVideos(mockHtml);
        for (String videoId : videoIds) {
            System.out.println("\n\tvideoId: " + videoId);
        }
    }       
}

接收以下输出到stdout：

photoId: 1236ad76-7433-fs34-50d1-b12bdbc308899af
photoId: 2346fe7d-c175-c380-4ab2-dda068b42b033dvf
videoId: 45064086-5d85-1866-4afc-a523c04c2b3e43b6

能够根据这些ID找到必要的资产，但我的问题是如何使用JSoup（例如，用于照片）替换整个标签（以及其内容，内联）：

<asset-entity type=\"photo\" id=\"4806ad76-7433-fs34-50d1-b12bdbc308899ad\">" + "</asset-entity>

具有：

<img src="AngelinaJolie.jpg">

因此，转换后的HTML如下所示：

"<img src="AngelinaJolie.jpg">\r\nAngelie Jolie was seen at Wholefoods with ex-beau Brad Pitt.\r\n <img src="BradPitt.jpg">
\r\n- The majority of their kids were with them.\r\n<video><source src="Brangelina.mp4" type="video/mp4"></video>\r\n";

有人能指出我正确的方向吗？

您实际上可以更改元素的tagName，然后尝试用您的属性替换其属性。

        Document doc = Jsoup.parse(html);
        doc.outputSettings().prettyPrint(false);
        Elements elements = doc.select("asset-entity[type=photo]");
        for (Element element : elements) {
            element.tagName("img");
            element.removeAttr("type");
            element.removeAttr("id");
            element.attr("src","AngelinaJolie.jpg");
        }
        String formattedHtml = doc.html();

如何使用JSoup用实际的HTML标签替换自定义HTML？
