JSoup从表td中提取文本，其中不包含任何html节点

Question

I have a html string like this :

String html="<table><tbody>
<tr>
<td><p>ABC</p></td>
<td>DEF</td>
</tr>
<tr>
<td><p>GHI</p></td>
<td>MNO</td>
</tr>
</tbody>
</table>";

I only need to extract the text which has no more child elements inside td tags.My current code returns me both text and html nodes.

Elements elements = doc.select("tbody > tr");
for (Element e : elements) {
    System.out.println(e.select("td").html());
}

But what I need as the out put is :

DEF
MNO

Thanks in advance.

Answer 1

It is not clear to me, if you want to just the the text of each td that is not port of a child of that td , or if you want to further exclude all tds that have children. Therefore you may have to adapt my solution a bit.

String html="<table><tbody>"
        +"<tr>"
        +"<td><p>ABC</p></td>"
        +"<td>DEF</td>"
        +"<td>DEF2<p>ABC</p></td>"
        +"</tr>"
        +"<tr>"
        +"<td><p>GHI</p></td>"
        +"<td>MNO</td>"
        +"<td>MNO2<p>GHI2</p></td>"
        +"</tr>"
        +"</tbody>"
        +"</table>";

Document doc = Jsoup.parse(html);
Elements elements = doc.select("tbody > tr > td:matchesOwn(.+)");
for (Element e : elements) {
    System.out.println(e.text());
}

The above solution looks for td elements that have any own text, ie that match the regular expression .+ (at least one character).

If you want to further weed out the tds that contain children, you can do this:

Document doc = Jsoup.parse(html);
Elements elements = doc.select("tbody > tr > td:matchesOwn(.+):not(:has(*))");
for (Element e : elements) {
    System.out.println(e.text());
}

This uses both, the :has() and the :not() pseudo selectors as explained in the JSOUP Docs

Answer 2

Try this CSS selector:

tbody > tr > td:not(:has(*))

DEMO

http://try.jsoup.org/~K4qiK0SxQDeuhE9FvvmUDa3vKKI

DESCRIPTION

tbody  /* Select any tbody */
> tr   /* Select any tr directly under it */
> td   /* Select any td directly under it ... */
:not(:has(*)) /* ... not having any element */

The * operator matches only elements . A text node is not an element. It's just a kind of Node.

SAMPLE CODE

Elements elements = doc.select("tbody > tr > td:not(:has(*))");
for (Element e : elements) {
    System.out.println(e.select("td").html());
}

OUTPUT

<td>DEF</td>
<td>MNO</td>

Answer 3

Try Element.child(int index) with index = 0 .

Elements elements = doc.select("tbody > tr");
for (Element e : elements) {
    for (Element el : e.select("td")) {
        // el.child(0)
    }
}
