从 <p> 个元素中提取标记的实体

Question

我的数据集具有以下结构：

<p>The <ORGANIZATION>Peter Hall Company</ORGANIZATION>'s production of ''Blithe Spirit,'' directed by <PERSON>Thea Sharrock</PERSON>, is one of those attractively and unimaginatively upholstered productions of brittle classics that become must-have middlebrow tickets every few years. Most notable for <PERSON>Penelope Keith</PERSON>'s startlingly brisk and no-nonsense interpretation of the madcap medium <ORGANIZATION>Madame Arcati</ORGANIZATION>, Ms. <PERSON>Sharrock</PERSON>'s take on <PERSON>Coward</PERSON>'s 1941 comedy of a man visited by his dead wife's impish spirit delivers bright badinage, dazed double takes and marital melees at the same efficient clip.</p>

如您所见，在标签 <p> 和 </p> 中有多个标记实体，例如 <ORGANIZATION>Peter Hall Company</ORGANIZATION> 和 <PERSON>Penelope Keith</PERSON>

我想使用 jsoup 列出 <p> 标签中包含的所有实体。

我猜 jsoup 应该能够处理这个问题，我已经看到一些与此特定实例相关的问题，但我无法让它们在我的情况下工作，这可能是因为 <ORGANIZATION> 和 <PERSON> 不是真正的 html 标签？我必须为那些使用正则表达式吗？如果我可以用 jsoup 做，怎么做？

到目前为止我试过这个：

    for (Iterator<Element> iterator = contents.iterator(); iterator.hasNext();)
    {
        Element content = iterator.next();
        String text = content.text();
        String title = content.select("PERSON").text();
        String output = text.replaceFirst(title, "").trim();
        System.out.println(output);
    }

还有这个：

    for (Element content : contents) 
    {
        String PERSON = content.attr("PERSON");
        String linkText = content.text();

        //print
        System.out.println(PERSON);
        System.out.println(linkText);
    }

两者均无效。

Answer 1

这可行，但不够优雅

            //people
            Elements contents_person = doc.getElementsByTag("p").select("PERSON");

            for (Element content : contents_person) 
            {
                //String PERSON = content.attr("PERSON");
                String linkText = content.text();

                //print
                //System.out.println(PERSON);
                System.out.println(linkText);
            }

            //places
            Elements contents_place = doc.getElementsByTag("p").select("LOCATION");

            for (Element content : contents_place) 
            {
                //String PERSON = content.attr("PERSON");
                String linkText = content.text();

                //print
                //System.out.println(PERSON);
                System.out.println(linkText);
            }

            //things
            Elements contents_things = doc.getElementsByTag("p").select("ORGANIZATION");

            for (Element content : contents_things) 
            {
                //String PERSON = content.attr("PERSON");
                String linkText = content.text();

                //print
                //System.out.println(PERSON);
                System.out.println(linkText);
            }

Answer 2

您只需要为此使用 css 选择器：

public class Foo {
    public static void main(String... args) {
        String xml = "<p>The <ORGANIZATION>Peter Hall Company</ORGANIZATION>'s production of ''Blithe Spirit,'' directed by <PERSON>Thea Sharrock</PERSON>, is one of those attractively and unimaginatively upholstered productions of brittle classics that become must-have middlebrow tickets every few years. Most notable for <PERSON>Penelope Keith</PERSON>'s startlingly brisk and no-nonsense interpretation of the madcap medium <ORGANIZATION>Madame Arcati</ORGANIZATION>, Ms. <PERSON>Sharrock</PERSON>'s take on <PERSON>Coward</PERSON>'s 1941 comedy of a man visited by his dead wife's impish spirit delivers bright badinage, dazed double takes and marital melees at the same efficient clip.</p>";
        Document doc = Jsoup.parse(xml);

        for (Element e: doc.select("p > ORGANIZATION, p > PERSON")) {
            System.out.printf("-> %s: %s\n", e.tagName(), e.text());
        }
    }
}

输出：

-> organization: Peter Hall Company
-> person: Thea Sharrock
-> person: Penelope Keith
-> organization: Madame Arcati
-> person: Sharrock
-> person: Coward

编辑：如果您想过滤掉这些标签并只保留内容，您可以在迭代元素时用它们的文本内容替换元素，如下所示：

public class Foo {
    public static void main(String... args) {
        String xml = "<p>The <ORGANIZATION>Peter Hall Company</ORGANIZATION>'s production of ''Blithe Spirit,'' directed by <PERSON>Thea Sharrock</PERSON>, is one of those attractively and unimaginatively upholstered productions of brittle classics that become must-have middlebrow tickets every few years. Most notable for <PERSON>Penelope Keith</PERSON>'s startlingly brisk and no-nonsense interpretation of the madcap medium <ORGANIZATION>Madame Arcati</ORGANIZATION>, Ms. <PERSON>Sharrock</PERSON>'s take on <PERSON>Coward</PERSON>'s 1941 comedy of a man visited by his dead wife's impish spirit delivers bright badinage, dazed double takes and marital melees at the same efficient clip.</p>";
        Document doc = Jsoup.parse(xml);

        for (Element e: doc.select("p > ORGANIZATION, p > PERSON")) {
            System.out.printf("-> %s: %s\n", e.tagName(), e.text());
            e.replaceWith(new TextNode(e.text(), ""));
        }

        System.out.println("\nFiltered out:\n" + doc.select("p").html());
    }
}

输出：

-> organization: Peter Hall Company
-> person: Thea Sharrock
-> person: Penelope Keith
-> organization: Madame Arcati
-> person: Sharrock
-> person: Coward

Filtered out:
The Peter Hall Company's production of ''Blithe Spirit,'' directed by Thea Sharrock, is one of those attractively and unimaginatively upholstered productions of brittle classics that become must-have middlebrow tickets every few years. Most notable for Penelope Keith's startlingly brisk and no-nonsense interpretation of the madcap medium Madame Arcati, Ms. Sharrock's take on Coward's 1941 comedy of a man visited by his dead wife's impish spirit delivers bright badinage, dazed double takes and marital melees at the same efficient clip.
