Method Detail

getEncoding

String getEncoding()

Return the encoding applied while reading the markup resource. The encoding is determined by analyzing the <?xml version=".." encoding=".." ?> tag.

Returns:

if null, JVM defaults have been used.

getDoctype

CharSequence getDoctype()

Gets the <!DOCTYPE ...> tag if found in the markup

Returns:

Null, if not found

getInputFromPositionMarker

CharSequence getInputFromPositionMarker(int toPos)

Wicket dissects the markup into Wicket relevant tags and raw markup, which is not further analyzed by Wicket. The method getInputFromPositionMarker() is used to access the raw markup.

Parameters:

toPos - To position

Returns:

The raw markup in between the position marker and toPos

getInput

CharSequence getInput(int fromPos,
                      int toPos)

Wicket dissects the markup into Wicket relevant tags and raw markup, which is not further analyzed by Wicket. The getInputSubsequence() method is used to access the raw markup.

Parameters:

fromPos - From position

toPos - To position

Returns:

The raw markup in between fromPos and toPos

parse

void parse(CharSequence string)
    throws IOException

Parse the markup provided. Use nextTag() to access the tags contained one after another.

Note: xml character encoding is NOT applied. It is assumed the input provided does have the correct encoding already.

Parameters:

string - The markup to be parsed

Throws:

IOException - Error while reading the resource

parse

void parse(InputStream inputStream)
    throws IOException

Reads and parses markup from an input stream, using UTF-8 encoding by default when not specified in XML declaration. Use nextTag() to access the tags contained, one after another.

Parameters:

inputStream - The input stream to read and parse

Throws:

IOException - Error while reading the resource

parse

void parse(InputStream inputStream,
           String encoding)
    throws IOException

Reads and parses markup from an input stream. Use nextTag() to access the tags contained, one after another.

Parameters:

inputStream - A resource like e.g. a file

encoding - Use null to apply JVM/OS default

Throws:

IOException - Error while reading the resource

next

IXmlPullParser.HttpTagType next()
                         throws ParseException

Move to the next XML element

Returns:

o, if end of file. Else a TAG, COMMENT etc.

Throws:

ParseException

getElement

XmlTag getElement()

Returns:

The current element

getString

CharSequence getString()

Returns:

The xml string from the last element

setPositionMarker

void setPositionMarker()

Set the position marker of the markup at the current position.

setPositionMarker

void setPositionMarker(int pos)

Set the position marker of the markup

Parameters:

pos -
