我有一个带有ID、TEXT等列的表，这里的TEXT是超文本标记语言FORMAT中包含数据的Clob列

样本数据：

当我使用Jsoup.parse（AUDIT_SCOPE_LOB.text（）时；我得到的数据如下

Start: 8:30 am End: 4 pm The goal of this visit is to conduct an intial assessment of systems and processes in place to support supply of materials for GMP clinical development and manufacturing of pharmaceuticals. A cGMP assessment of specific processes, procedures, ad the general quality systems will occur as outlined below. The following items represent the scope and visit focus areas: 1. SOP Program 2. Training Program 3. Calibration/Preventive Maintenance Program

我对java知之甚少。我可以使用jsoup获取java代码来提取数据并重新运行下面的outpu吗

Start: 8:30 am
End: 4 pm

1. SOP Program
2. Training Program
3. Calibration/Preventive Maintenance Program

实际上，这个数据是一个样本数据。我有一些带有html标记的数据，这里没有提到。

org.jsoup.nodes.Element.toString（）返回org.jsoup.nodes.Element.outerHTML（）

获取此节点的外部HTML。

org.jsoup.nodes.Element.text()

获取此元素及其所有子元素的组合文本。空白被规范化和修剪。

因此，对整个示例调用toString（）将返回与输出相同的结果。同样，调用text（）将以单个字符串的形式返回所有不带标记的文本。但是，您需要的是每个文本段落的单个字符串。

您的某些段落标记为空。为了获得示例中的输出，您应该首先验证每个段落是否有文本。

Document doc = Jsoup.parse(AUDIT_SCOPE_LOB, "UTF-8");

for (Element p : doc.select("p"))
    if (p.hasText())
        System.out.println(p.text());

输出

Start: 8:30 am
End: 4 pm

1. SOP Program
2. Training Program
3. Calibration/Preventive Maintenance Program

查看CSS选择器，了解更多如何解析数据的示例。例如，如果要解析出有序列表，可以在类名上选择并检索列表中的第二个跨度。

for (Element span : doc.select("p.MsoNormal > span:nth-child(2)")) 
     System.out.println(span.ownText());

输出

SOP Program
Training Program
Calibration/Preventive Maintenance Program

由于信息分为

Document doc = Jsoup.parse(AUDIT_SCOPE_LOB);
    Elements el = doc.select("p");
    for (Element e : el) {
        System.out.println(e.text());
    }
