I am generating a PDF from HTML, but instead of interpreting it as normal text my PDF pages are filled with html tags like <p>, <li>, etc.
You'll need to remove all tags and unescape special chars.
PHP example:
$text = preg_replace($html, '<[^>]*>', '');
$text = html_entity_decode($text);
VB.NET example:
Dim text As String = Regex.Replace(html, "<[^>]*>", "")
text = System.Web.WebUtility.HtmlDecode(text)
Java example:
text = html.replaceAll("<[^>]*>", "");
For the html entity decoding you'll find a good answer here: Java: How to unescape HTML character entities in Java?. Otherwise you could just replace them if you know all of them ( , ", ...).

I have a sample code as below.
String sample = "<html>
<head>
</head>
<body>
This is a sample on parsing html body using jsoup
This is a sample on parsing html body using jsoup
</body>
</html>";
Document doc = Jsoup.parse(sample);
String output = doc.body().text();
I get the output as
This is a sample on parsing html body using jsoup This is a sample on `parsing html body using jsoup`
But I want the output as
This is a sample on parsing html body using jsoup
This is a sample on parsing html body using jsoup
How do parse it so that I get this output? Or is there another way to do so in Java?
You can disable the pretty printing of your document to get the output like you want it. But you also have to change the .text() to .html().
Document doc = Jsoup.parse(sample);
doc.outputSettings(new Document.OutputSettings().prettyPrint(false));
String output = doc.body().html();
The HTML specification requires that multiple whitespace characters are collapsed into a single whitespace. Therefore, when parsing the sample, the parser correctly eliminates the superfluous whitespace characters.
I don't think you can change how the parser works. You could add a preprocessing step where you replace multiple whitespaces with non-breakable spaces ( ), which will not collapse. The side effect, though, would of course be that those would be, well, non-breakable (which doesn't matter if you really just want to use the rendered text, as in doc.body().text()).
I'm parsing a HTML file using Jsoup. When getting the text of a h1 it retrieves also tabulations and newlines.
'Name' is what I'm trying to retreive from here:
<h1>\n\t\t\tNAME\n\t\t</h1>
I'm trying to get rid of these characters this way:
String name = document.select( "div header > h1" ).first().ownText().replaceAll( "[^a-zA-Z]+", "" ).trim().toUpperCase();
But this is the result:
NTTTTNAMETNTTT
How can I get the text without all the tabulations and newlines characters?
It seems that the html really contains the strings "\t" and "\n" literally. In that case you probably should clean the source prior to parsing. Something like this should do:
String html = Jsoup.connect(URL).userAgent("Mozilla/5.0").execute().body();
html = html.replaceAll("\\\\[nt]", "");
Document doc = Jsoup.parse(html);
I have a html content as a string.
String attachment = "<div style=\"color:black;font-style:normal;font-size:10pt;font-family:verdana;\"><div><span style=\"background-color: rgb(255,255,255);\">This is special "'; </span></div></div>";
If I try to add this as a multipart form data I get an exception. The reason happens to be the special characters inside the html which is " and '. So I tried escaping the entire string using
org.apache.commons.lang.StringEscapeUtils.escapeJave(attachment);
After doing this the exception disappeared and it was working fine. But the double quotes used for the attributes, like style are also escaped using this method, which is not desired.
Instead of <div> style="color:black;
it was sent as <div> style=\"color:black;
So far I realized that I need to escape only the text inside the html content and not the entire text. i could extract the text content using jsoup or something else then form the html again.
But is there a generic easy solution to do this?
I am trying to clean HTML text and to extract plain text from it using Jsoup. The HTML might contain non-english character.
For example the HTML text is:
String html = "<p>Á <a href='http://example.com/'><b>example</b></a> link.</p>";
Now if I use Jsoup#parse(String html):
String text = Jsoup.parse(html).text();
It is printing:
Á example link.
And if I clean the text using Jsoup#clean(String bodyHtml, Whitelist whitelist):
String text = Jsoup.clean(html, Whitelist.none());
It is printing:
Á example link.
My question is, how can I get the text
Á example link.
using Whitelist and clean() method? I want to use Whitelist since I might be needed to use Whitelist#addTags(String... tags).
Any information will be very helpful to me.
Thanks.
Not possible in current version (1.6.1), jsoup print Á as Á because the entity escaping feature, there is no "don't escape" mode now (check Entities.EscapeMode).
You can 1. unescape these HTML entities, 2. extend jsoup's source code by adding a new escape mode with an empty map.
Can anyone help me in extracting text from within the html tags to plain text?
I have parsed an xml and get some output as body which has html tags now i want to remove the tags and use the text.
thanks in advance!!!!
You can use HTML Parser like JSoup
For example
HTML is
<div style="height:240px;"><br>test: example<br>test1:example1</div>
You can get the html using
Document document = Jsoup.parse(html);
Element div = document.select("div[style=height:240px;]").first();
div.html();
Try a HTML Parser.
If the HTML is escaped, i.e. < instead of < you might have to decode first.
Considering your requirements you might try Jericho HTML Parser
Take a look at TextExtractor class:
Using the default settings, the source segment:
"<div><b>O</b>ne</div><div title="Two"><b>Th</b><script>//a script </script>ree</div>"
produces the text "One Two Three".
If all you want to do is remove HTML tags from a string, you can do this:
String output = input.replaceAll("(?s)\\<.*?\\>", " ");
