      • scriptBlock

        private boolean scriptBlock
        True if a <script></script> or <style></style> block is read. CDATA sections within are handled as rawText.

      • isLink

        private boolean isLink
        Used to distinguish <a href=""> from <a name="">.

                               Sink sink)

        Goes through a common list of possible html5 start tags. These include only tags that can go into the body of an xhtml5 document and so should be re-usable by different xhtml-based parsers.

        The currently handled tags are:

        <article>, <nav>, <aside>, <section>, <h1>, <h2>, <h3>, <h4>, <h5>, <header>, <main>, <footer>, <em>, <strong>, <small>, <s>, <cite>, <q>, <dfn>, <abbr>, <i>, <b>, <code>, <samp>, <kbd>, <sub>, <sup>, <u>, <mark>, <ruby>, <rb>, <rt>, <rtc>, <rp>, <bdi>, <bdo>, <span>, <ins>, <del>, <p>, <pre>, <ul>, <ol>, <li>, <dl>, <dt>, <dd>, <a>, <table>, <tr>, <th>, <td>, <caption>, <br/>, <wbr/>, <hr/>, <img/>.

        Parameters:
        parser - A parser.
        sink - the sink to receive the events.
        Returns:
        True if the event has been handled by this method, i.e. the tag was recognized, false otherwise.

      • baseStartTag

        protected boolean baseStartTag​(java.lang.String elementName,
                               SinkEventAttributeSet attribs,

                             Sink sink)

        Goes through a common list of possible html end tags. These should be re-usable by different xhtml-based parsers. The tags handled here are the same as for baseStartTag(XmlPullParser,Sink), except for the empty elements (<br/>, <hr/>, <img/>).

        Parameters:
        parser - A parser.
        sink - the sink to receive the events.
        Returns:
        True if the event has been handled by this method, false otherwise.

                              MacroExecutionException
        Goes through the possible start tags. Just calls baseStartTag(XmlPullParser,Sink), this should be overridden by implementing parsers to include additional tags.

                            MacroExecutionException

                   throws org.codehaus.plexus.util.xml.pull.XmlPullParserException
        Handles text events.

        This is a default implementation, if the parser points to a non-empty text element, it is emitted as a text event into the specified sink.

      • emitHeadingSections

        protected void emitHeadingSections​(int newLevel,
                                   Sink sink,
                                   boolean enforceNewSection)
        Make sure sections are nested consecutively and correctly inserted for the given heading level

        HTML5 heading tags H1 to H5 imply same level sections in Sink API (compare with Sink.sectionTitle(int, SinkEventAttributes)). However (X)HTML5 allows headings without explicit surrounding section elements and is also less strict with non-consecutive heading levels. This methods both closes open sections which have been added for previous headings and/or opens sections necessary for the new heading level. At least one section needs to be opened directly prior the heading due to Sink API restrictions.

        For instance, if the following sequence is parsed: 

         <h2></h2>
 <h5></h5>

        we have to insert two section starts before we open the <h5>. In the following sequence 

         <h5></h5>
 <h2></h2>

        we have to close two sections before we open the <h2>.

        The current heading level is set to newLevel afterwards.

        Parameters:
        newLevel - the new section level, all upper levels have to be closed.
        sink - the sink to receive the events.
        enforceNewSection - whether to enforce a new section or not

        Close open heading sections.
        Parameters:
