I need to extract text from a node like this:
Some text with tags might go here.
Also there are paragraphs<
Assuming you want text only (no tags) my solution is below.
Output is:
Some text with tags might go here. Also there are paragraphs. More text can go without paragraphs
public static void main(String[] args) throws IOException {
String str =
"<div>"
+ " Some text <b>with tags</b> might go here."
+ " <p>Also there are paragraphs.</p>"
+ " More text can go without paragraphs<br/>"
+ "</div>";
Document doc = Jsoup.parse(str);
Element div = doc.select("div").first();
StringBuilder builder = new StringBuilder();
stripTags(builder, div.childNodes());
System.out.println("Text without tags: " + builder.toString());
}
/**
* Strip tags from a List of type <code>Node</code>
* @param builder StringBuilder : input and output
* @param nodesList List of type <code>Node</code>
*/
public static void stripTags (StringBuilder builder, List<Node> nodesList) {
for (Node node : nodesList) {
String nodeName = node.nodeName();
if (nodeName.equalsIgnoreCase("#text")) {
builder.append(node.toString());
} else {
// recurse
stripTags(builder, node.childNodes());
}
}
}
you can use TextNode for this purpose:
List<TextNode> bodyTextNode = doc.getElementById("content").textNodes();
String html = "";
for(TextNode txNode:bodyTextNode){
html+=txNode.text();
}
Element.children() returns an Elements object - a list of Element objects. Looking at the parent class, Node, you'll see methods to give you access to arbitrary nodes, not just Elements, such as Node.childNodes().
public static void main(String[] args) throws IOException {
String str = "<div>" +
" Some text <b>with tags</b> might go here." +
" <p>Also there are paragraphs</p>" +
" More text can go without paragraphs<br/>" +
"</div>";
Document doc = Jsoup.parse(str);
Element div = doc.select("div").first();
int i = 0;
for (Node node : div.childNodes()) {
i++;
System.out.println(String.format("%d %s %s",
i,
node.getClass().getSimpleName(),
node.toString()));
}
}
Result:
1 TextNode Some text 2 Element <b>with tags</b> 3 TextNode might go here. 4 Element <p>Also there are paragraphs</p> 5 TextNode More text can go without paragraphs 6 Element <br/>
for (Element el : doc.select("body").select("*")) {
for (TextNode node : el.textNodes()) {
node.text() ));
}
}
