问题：
使用java中的JSOUP库从HTML中读取内容
商昆琦
我有如下的HTML电子邮件体。
我想获取emailBody中存在的每个元素（公司、优先级、描述等），最后生成Json键值对。
我希望通过使用JSOUP库我们能够实现这一点。

预期输出如下所示：
Ticket Type=Incident,
Company=Grupo Bimbo DSDE,
Configuration Item=null,
Priority=P3-Moderate,
Short Description=null,
Description=null
有人能帮我解决这个问题吗？

在调试了Java代码之后，我找到了我的用例的解决方案。
解决方案代码：
Document doc = Jsoup.parse(htmlContent);
List<String> keys = new ArrayList<>();
List<Map<String, String>> dataPairs = new ArrayList<>();
Map<String, String> map = new HashMap<>();
Elements trElements = doc.getElementsByTag("tr");
//logger.info("trElements::" + trElements);
for (int i = 0; i < trElements.size(); i++) {
Element element = trElements.get(i);
Elements pElements = element.getElementsByTag("td");
//logger.info("pElements::" + pElements);
for (int i1 = 0; i1 < pElements.size(); i1++) {
Element p = pElements.get(i1);
if (i1 == 0)
keys.add(p.text());
else
map.put(keys.get(i), p.text());
}
}
logger.info("Map::" + map.entrySet());
产出：
[Configuration Item: = , Ticket Type: =Incident , Description: = , Priority: =P3-Moderate , Short Description: = , Company: =Grupo Bimbo DSDE ]
