Method Detail

parse

public static Document parse(String html,
                             String baseUri)
Parse HTML into a Document. The parser will make a sensible, balanced document tree out of any HTML.

Parameters:
html - HTML to parse
baseUri - The URL where the HTML was retrieved from. Used to resolve relative URLs to absolute URLs, that occur before the HTML declares a <base href> tag.
Returns:
sane HTML

parse

public static Document parse(String html)
Parse HTML into a Document. As no base URI is specified, absolute URL detection relies on the HTML including a <base href> tag.

Parameters:
html - HTML to parse
Returns:
sane HTML
See Also:
parse(String, String)

connect

public static Connection connect(String url)
Creates a new Connection to a URL. Use to fetch and parse a HTML page.

Use examples:

Parameters:
url - URL to connect to. The protocol must be http or https.
Returns:
the connection. You can add data, cookies, and headers; set the user-agent, referrer, method; and then execute.

parse

public static Document parse(File in,
                             String charsetName,
                             String baseUri)
                      throws IOException
Parse the contents of a file as HTML.

Parameters:
in - file to load HTML from
charsetName - (optional) character set of file contents. Set to null to determine from http-equiv meta tag, if present, or fall back to UTF-8 (which is often safe to do).
baseUri - The URL where the HTML was retrieved from, to resolve relative links against.
Returns:
sane HTML
Throws:
IOException - if the file could not be found, or read, or if the charsetName is invalid.

parse

public static Document parse(File in,
                             String charsetName)
                      throws IOException
Parse the contents of a file as HTML. The location of the file is used as the base URI to qualify relative URLs.

Parameters:
in - file to load HTML from
charsetName - (optional) character set of file contents. Set to null to determine from http-equiv meta tag, if present, or fall back to UTF-8 (which is often safe to do).
Returns:
sane HTML
Throws:
IOException - if the file could not be found, or read, or if the charsetName is invalid.
See Also:
parse(File, String, String)

parse

public static Document parse(InputStream in,
                             String charsetName,
                             String baseUri)
                      throws IOException
Read an input stream, and parse it to a Document.

Parameters:
in - input stream to read. Make sure to close it after parsing.
charsetName - (optional) character set of file contents. Set to null to determine from http-equiv meta tag, if present, or fall back to UTF-8 (which is often safe to do).
baseUri - The URL where the HTML was retrieved from, to resolve relative links against.
Returns:
sane HTML
Throws:
IOException - if the file could not be found, or read, or if the charsetName is invalid.

parseBodyFragment

public static Document parseBodyFragment(String bodyHtml,
                                         String baseUri)
Parse a fragment of HTML, with the assumption that it forms the body of the HTML.

Parameters:
bodyHtml - body HTML fragment
baseUri - URL to resolve relative URLs against.
Returns:
sane HTML document
See Also:
Document.body()

parseBodyFragment

public static Document parseBodyFragment(String bodyHtml)
Parse a fragment of HTML, with the assumption that it forms the body of the HTML.

Parameters:
bodyHtml - body HTML fragment
Returns:
sane HTML document
See Also:
Document.body()

parse

public static Document parse(URL url,
                             int timeoutMillis)
                      throws IOException
Fetch a URL, and parse it as HTML. Provided for compatibility; in most cases use connect(String) instead.

The encoding character set is determined by the content-type header or http-equiv meta tag, or falls back to UTF-8.

Parameters:
url - URL to fetch (with a GET). The protocol must be http or https.
timeoutMillis - Connection and read timeout, in milliseconds. If exceeded, IOException is thrown.
Returns:
The parsed HTML.
Throws:
IOException - If the final server response != 200 OK (redirects are followed), or if there's an error reading the response stream.
See Also:
connect(String)

clean

public static String clean(String bodyHtml,
                           String baseUri,
                           Whitelist whitelist)
Get safe HTML from untrusted input HTML, by parsing input HTML and filtering it through a white-list of permitted tags and attributes.

Parameters:
bodyHtml - input untrusted HMTL
baseUri - URL to resolve relative URLs against
whitelist - white-list of permitted HTML elements
Returns:
safe HTML
See Also:
Cleaner.clean(Document)

clean

public static String clean(String bodyHtml,
                           Whitelist whitelist)
Get safe HTML from untrusted input HTML, by parsing input HTML and filtering it through a white-list of permitted tags and attributes.

Parameters:
bodyHtml - input untrusted HTML
whitelist - white-list of permitted HTML elements
Returns:
safe HTML
See Also:
Cleaner.clean(Document)

isValid

public static boolean isValid(String bodyHtml,
                              Whitelist whitelist)
Test if the input HTML has only tags and attributes allowed by the Whitelist. Useful for form validation. The input HTML should still be run through the cleaner to set up enforced attributes, and to tidy the output.

Parameters:
bodyHtml - HTML to test
whitelist - whitelist to test against
Returns:
true if no tags or attributes were removed; false otherwise

clean(String, org.jsoup.safety.Whitelist)
