Java Jsoup - 元素未从元素中删除

我将从头开始,有这样的模式的html:

<div id="post_message_(some numeric id)">
    <div style="some style things">
        <div class="smallfont" style="some style">useless text</div>
        <table cellpading="6" cellspaceing=.......> a lot of text inside i dont need</table>
    </div>
    Text i need
</div>

那些带有样式的div和那个表是可选的,有时只有

<div id="post">
     Text i need
</div>

我想将该文本解析为String。这里;我正在使用的代码

Elements divsInside = element.getElementById("post_message_" + id).getElementsByTag("div");
    for(Element div : divsInside) {
        if(div != null && div.attr("style").equals("margin:20px; margin-top:5px; ")) {
            System.out.println(div.html());
            div.remove();
            System.out.println("div removed");
        }
    }

我添加了那些打印行以检查它是否找到它们,是的,它确实找到了正确的打印行,但后来当我将其解析为String时:

String message = Jsoup.parse(divsInside.html().replaceAll("(?i)<br[^>]*>", "br2n")).text()
            .replaceAll("br2n", "\n");

由于某些原因,String包含所有删除的内容。

我尝试通过迭代器删除它们,或者通过索引完全删除元素,但结果是相同的。

所以你想获得Text i need。使用Element的{​​{1}} ownText()方法Gets the text owned by this element only; does not get the combined text of all children

 private static void test(String htmlFile) {
    File input = null;
    Document doc = null;
    Element specificIdDiv = null;

    try {
        input = new File(htmlFile);
        doc = Jsoup.parse(input, "ASCII", "");
        doc.outputSettings().charset("ASCII");
        doc.outputSettings().escapeMode(EscapeMode.base);

        /** Get Element id = post_message_1 **/
        specificIdDiv = doc.getElementById("post_message_1");

        if (specificIdDiv != null ) {
            System.out.println("content: " + specificIdDiv.ownText());
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}
