Method Details
-
parse
Parses the given source model and emits Doxia events into the given sink.- Specified by:
parse
in interfaceParser
- Overrides:
parse
in classAbstractXmlParser
- Parameters:
source
- not null reader that provides the source document. You could usenewReader
methods fromReaderFactory
.sink
- A sink that consumes the Doxia events.reference
- a string identifying the source (for file based documents the source file path)- Throws:
ParseException
- if the model could not be parsed.
-
initXmlParser
protected void initXmlParser(org.codehaus.plexus.util.xml.pull.XmlPullParser parser) throws org.codehaus.plexus.util.xml.pull.XmlPullParserException Initializes the parser with custom entities or other options. Adds all XHTML (HTML 5.2) entities to the parser so that they can be recognized and resolved without additional DTD.- Overrides:
initXmlParser
in classAbstractXmlParser
- Parameters:
parser
- A parser, not null.- Throws:
org.codehaus.plexus.util.xml.pull.XmlPullParserException
- if there's a problem initializing the parser
-
baseStartTag
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
-
baseEndTag
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.
-
baseEndTag
-
handleStartTag
protected void handleStartTag(org.codehaus.plexus.util.xml.pull.XmlPullParser parser, Sink sink) throws org.codehaus.plexus.util.xml.pull.XmlPullParserException, MacroExecutionException Goes through the possible start tags. Just callsbaseStartTag(XmlPullParser,Sink)
, this should be overridden by implementing parsers to include additional tags.- Specified by:
handleStartTag
in classAbstractXmlParser
- Parameters:
parser
- A parser, not null.sink
- the sink to receive the events.- Throws:
org.codehaus.plexus.util.xml.pull.XmlPullParserException
- if there's a problem parsing the modelMacroExecutionException
- if there's a problem executing a macro
-
handleEndTag
protected void handleEndTag(org.codehaus.plexus.util.xml.pull.XmlPullParser parser, Sink sink) throws org.codehaus.plexus.util.xml.pull.XmlPullParserException, MacroExecutionException Goes through the possible end tags. Just callsbaseEndTag(XmlPullParser,Sink)
, this should be overridden by implementing parsers to include additional tags.- Specified by:
handleEndTag
in classAbstractXmlParser
- Parameters:
parser
- A parser, not null.sink
- the sink to receive the events.- Throws:
org.codehaus.plexus.util.xml.pull.XmlPullParserException
- if there's a problem parsing the modelMacroExecutionException
- if there's a problem executing a macro
-
handleText
protected void handleText(org.codehaus.plexus.util.xml.pull.XmlPullParser parser, Sink sink) 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.
- Overrides:
handleText
in classAbstractXmlParser
- Parameters:
parser
- A parser, not null.sink
- the sink to receive the events. Not null.- Throws:
org.codehaus.plexus.util.xml.pull.XmlPullParserException
- if there's a problem parsing the model
-
handleComment
protected void handleComment(org.codehaus.plexus.util.xml.pull.XmlPullParser parser, Sink sink) throws org.codehaus.plexus.util.xml.pull.XmlPullParserException Handles comments.This is a default implementation, all data are emitted as comment events into the specified sink.
- Overrides:
handleComment
in classAbstractXmlParser
- Parameters:
parser
- A parser, not null.sink
- the sink to receive the events. Not null.- Throws:
org.codehaus.plexus.util.xml.pull.XmlPullParserException

-
handleCdsect
protected void handleCdsect(org.codehaus.plexus.util.xml.pull.XmlPullParser parser, Sink sink) throws org.codehaus.plexus.util.xml.pull.XmlPullParserException Handles CDATA sections.This is a default implementation, all data are emitted as text events into the specified sink.

consecutiveSections
@Deprecated protected void consecutiveSections(int newLevel, Sink sink, SinkEventAttributeSet attribs) Deprecated.UseemitHeadingSections(int, Sink, boolean)

with last argument beingtrue
- Parameters:
newLevel
-sink
-attribs
-
-
emitHeadingSections
Make sure sections are nested consecutively and correctly inserted for the given heading levelHTML5 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
-
isLastEventSectionStart
private boolean isLastEventSectionStart() -
closeOpenHeadingSections
Close open heading sections.- Parameters:
newLevel
- the new section level, all upper levels have to be closed.sink
- the sink to receive the events.
-
openMissingHeadingSections
Open missing heading sections.- Parameters:
newLevel
- the new section level, all lower levels have to be opened.sink
- the sink to receive the events.
-
getSectionLevel
protected int getSectionLevel()Return the current section level.- Returns:
- the current section level.
-
setSectionLevel
protected void setSectionLevel(int newLevel) Set the current section level.- Parameters:
newLevel
- the new section level.
-
verbatim_
protected void verbatim_()Stop verbatim mode. -
verbatim
protected void verbatim()Start verbatim mode. -
isVerbatim
protected boolean isVerbatim()Checks if we are currently inside a <pre> tag.- Returns:
- true if we are currently in verbatim mode.
-
isScriptBlock
protected boolean isScriptBlock()Checks if we are currently inside a <script> tag.- Returns:
- true if we are currently inside
<script>
tags. - Since:
- 1.1.1.
-
validAnchor
Checks if the given id is a valid Doxia id and if not, returns a transformed one.- Parameters:
id
- The id to validate.- Returns:
- A transformed id or the original id if it was already valid.
