Jsoup 从 html 获取数据<br>标签
[英]Jsoup to fetch data from html betwwen two <br> tags
问题描述
I am working on a personal project and wants to parse this html and retrieve information from this.
我正在做一个个人项目，想解析这个 html 并从中检索信息。
Basically I want to get all the information that is given inside the 'br' tags,for this I am using JSOUP in java.基本上我想获取“br”标签中给出的所有信息，为此我在 java 中使用 JSOUP。
I want to store these value as pairs in a map (key,value).我想将这些值作为对存储在 map（键，值）中。

I am using this code to fetch but this is giving all values in a paragraph.我正在使用此代码来获取，但这会给出段落中的所有值。
Document doc = Jsoup.parse(htmlString);
List<String> valueList = new ArrayList<>();
Elements keyElements = doc.getElementsByTag("td");
for (Element keyElement : keyElements) {
String value = keyElement.text();
// store in value list
}
I also tried我也试过
doc.getElementsByTag("br");
but his is giving empty value.但他的价值是空的。
I want to store each the values in a map like this but not able to separate the value from html as this is coming in paragraph or empty.我想像这样将每个值存储在 map 中，但无法将值与 html 分开，因为这是在段落中或为空的。
My Map..我的 Map..
Key VALUE

You can use this solution:您可以使用此解决方案：
Document.OutputSettings outputSettings = new Document.OutputSettings();
outputSettings.prettyPrint(false);
doc.outputSettings(outputSettings);
doc.select("br").before("\\n");;
doc.select("p").before("\\n");
String str = doc.html().replaceAll("\\\\n", "\n");
String strWithNewLines = Jsoup.clean(str, "", Safelist.none(), outputSettings);
System.out.println(strWithNewLines);

I suppose you can try this:我想你可以试试这个：

You can use Element.wholeText() method to preserve line separators.您可以使用Element.wholeText()方法来保留行分隔符。
Unfortunately it looks like it also preserves depth of indentation so you would need to remove leading spaces or tabulators in each line.不幸的是，它看起来还保留了缩进深度，因此您需要删除每行中的前导空格或制表符。
Demo:演示：
String htmlString = "..."; // <--- replace with your HTML
Document doc = Jsoup.parse(htmlString);
Elements keyElements = doc.getElementsByTag("td");
for (Element keyElement : keyElements) {
String value = keyElement
.wholeText()
.trim()
.replaceAll("(?m)^[ \t]+",""); //remove leading spaces and tabs from each line
System.out.println(value);
System.out.println("---");
}
