java - 文本节点 xpath 的 Jsoup CSS 选择器

Question

HTML代码发布在最后，我想选择“OF”元素。 这是 CSS 选择器

Elements position = doc.select("#content > table:nth-child(4) > tbody > tr > td:nth-child(1) > table > tbody > tr:nth-child(1) > td > div:nth-child(5) > strong:nth-child(4)");

for (Element p : position) {
    System.out.println(p);
}

这是输出

p returns "<strong>Position:</strong>"
p.text() returns "Position:"

当我突出显示“OF”时，来自 chrome 的 xpath:

//*@id="content"]/table[1]/tbody/tr/td[1]/table/tbody/tr[1]/td/div[3]/text()[4]

HTML 代码

<div style="font-size: 10pt; padding-left:5px;">
     <strong>Birthdate:</strong> 8/7/1991 (23 y, 6 m, 10 d) &nbsp;&nbsp;&nbsp;&nbsp;
     <strong>Bats/Throws:</strong> R/R &nbsp;&nbsp;&nbsp;&nbsp;

您不能为文本节点编写 css 选择器(“OF”是目标 div 元素中包含的第四个文本节点)。 因此，您需要像这样以编程方式获取(需要 jsoup >= 1.6.2):

// select container div element
Elements position = doc.select("#content > table:nth-child(4) > tbody > tr > td:nth-child(1) > table > tbody > tr:nth-child(1) > td > div:nth-child(5)");
// extract the element from the list returned
Element element = ....
// TODO will need to check that the List exists and have at least four elements here
TextNode ofNode = element.textNodes().get(4);
ofNode.text(); // this will contain "OF"
