Constructor Detail

Parser

public Parser(org.jsoup.parser.TreeBuilder treeBuilder)

Create a new Parser, using the specified TreeBuilder

Parameters:

treeBuilder - TreeBuilder to use to parse input into Documents.

Method Detail

parseInput

public Document parseInput(String html,
                           String baseUri)

parseInput

public Document parseInput(Reader inputHtml,
                           String baseUri)

getTreeBuilder

public org.jsoup.parser.TreeBuilder getTreeBuilder()

Get the TreeBuilder currently in use.

Returns:

current TreeBuilder.

setTreeBuilder

public Parser setTreeBuilder(org.jsoup.parser.TreeBuilder treeBuilder)

Update the TreeBuilder used when parsing content.

Parameters:

treeBuilder - current TreeBuilder

Returns:

this, for chaining

isTrackErrors

public boolean isTrackErrors()

Check if parse error tracking is enabled.

Returns:

current track error state.

setTrackErrors

public Parser setTrackErrors(int maxErrors)

Enable or disable parse error tracking for the next parse.

Parameters:

maxErrors - the maximum number of errors to track. Set to 0 to disable.

Returns:

this, for chaining

getErrors

public List<ParseError> getErrors()

Retrieve the parse errors, if any, from the last parse.

Returns:

list of parse errors, up to the size of the maximum errors tracked.

settings

public Parser settings(ParseSettings settings)

settings

public ParseSettings settings()

parse

public static Document parse(String html,
                             String baseUri)

Parse HTML into a Document.

Parameters:

html - HTML to parse

baseUri - base URI of document (i.e. original fetch location), for resolving relative URLs.

Returns:

parsed Document

parseFragment

public static List<Node> parseFragment(String fragmentHtml,
                                       Element context,
                                       String baseUri)

Parse a fragment of HTML into a list of nodes. The context element, if supplied, supplies parsing context.

Parameters:

fragmentHtml - the fragment of HTML to parse

context - (optional) the element that this HTML fragment is being parsed for (i.e. for inner HTML). This provides stack context (for implicit element creation).

baseUri - base URI of document (i.e. original fetch location), for resolving relative URLs.

Returns:

list of nodes parsed from the input HTML. Note that the context element, if supplied, is not modified.

parseFragment

public static List<Node> parseFragment(String fragmentHtml,
                                       Element context,
                                       String baseUri,
                                       ParseErrorList errorList)

Parse a fragment of HTML into a list of nodes. The context element, if supplied, supplies parsing context.

Parameters:

fragmentHtml - the fragment of HTML to parse

context - (optional) the element that this HTML fragment is being parsed for (i.e. for inner HTML). This provides stack context (for implicit element creation).

baseUri - base URI of document (i.e. original fetch location), for resolving relative URLs.

errorList - list to add errors to

Returns:

list of nodes parsed from the input HTML. Note that the context element, if supplied, is not modified.

parseXmlFragment

public static List<Node> parseXmlFragment(String fragmentXml,
                                          String baseUri)

Parse a fragment of XML into a list of nodes.

Parameters:

fragmentXml - the fragment of XML to parse

baseUri - base URI of document (i.e. original fetch location), for resolving relative URLs.

Returns:

list of nodes parsed from the input XML.

parseBodyFragment

public static Document parseBodyFragment(String bodyHtml,
                                         String baseUri)

Parse a fragment of HTML into the body of a Document.

Parameters:

bodyHtml - fragment of HTML

baseUri - base URI of document (i.e. original fetch location), for resolving relative URLs.

Returns:

Document, with empty head, and HTML parsed into body

unescapeEntities

public static String unescapeEntities(String string,
                                      boolean inAttribute)

Utility method to unescape HTML entities from a string

Parameters:

string - HTML escaped string

inAttribute - if the string is to be escaped in strict mode (as attributes are)

Returns:

an unescaped string

parseBodyFragmentRelaxed

public static Document parseBodyFragmentRelaxed(String bodyHtml,
                                                String baseUri)

Deprecated. Use parseBodyFragment(java.lang.String, java.lang.String) or parseFragment(java.lang.String, org.jsoup.nodes.Element, java.lang.String) instead.

Parameters:

bodyHtml - HTML to parse

baseUri - baseUri base URI of document (i.e. original fetch location), for resolving relative URLs.

Returns:

parsed Document

htmlParser

public static Parser htmlParser()

Create a new HTML parser. This parser treats input as HTML5, and enforces the creation of a normalised document, based on a knowledge of the semantics of the incoming tags.

Returns:

a new HTML parser.

xmlParser

public static Parser xmlParser()

Create a new XML parser. This parser assumes no knowledge of the incoming tags and does not treat it as HTML, rather creates a simple tree directly from the input.

Returns:

a new simple XML parser.
