A helper class for creating XML or HTML markup. The builder supports various 'pretty printed' formats.
Example:
new MarkupBuilder().root {
a( a1:'one' ) {
b { mkp.yield( '3 <
5' ) }
c( a2:'two', 'blah' )
}
}
Will print the following to System.out:
<root> <a a1='one'> <b>3 < 5</b> <c a2='two'>blah</c> </a> </root>Notes:
mkp
is a special namespace used to escape
away from the normal building mode of the builder and get access
to helper markup methods such as 'yield' and 'yieldUnescaped'.
See the javadoc for getMkp() for further details.Constructor and description |

Prints markup to System.out
Sends markup to the given PrintWriter
pw
- the PrintWriter to useSends markup to the given Writer but first wrapping it in a PrintWriter
writer
- the writer to useSends markup to the given IndentPrinter. Use this option if you want to customize the indent used or provide your own IndentPrinter.
out
- the IndentPrinter to use Returns true
if attribute values are output with
double quotes; false
if single quotes are used.
By default, single quotes are used.
Property that may be called from within your builder closure to access helper methods, namely MarkupBuilderHelper.yield, MarkupBuilderHelper.yieldUnescaped, MarkupBuilderHelper.pi, MarkupBuilderHelper.xmlDeclaration and MarkupBuilderHelper.comment.
Returns the escapeAttributes property value.
Whether empty elements are expanded from <tagName/> to <tagName></tagName>.
true
, if empty elements will be represented by an opening tag
followed immediately by a closing tag.Determine whether empty attributes will appear in the produced markup.
true
, if empty attributes will be
removed from the resulting markup.Determine whether null attributes will appear in the produced markup.
true
, if null attributes will be
removed from the resulting markup.Sets whether the builder outputs attribute values in double quotes or single quotes.
useDoubleQuotes
- If this parameter is true
,
double quotes are used; otherwise, single quotes are.Defaults to true. If set to false then you must escape any special characters within attribute values such as '&', '<', CR/LF, single and double quotes etc. manually as needed. The builder will not guard against producing invalid XML when in this mode and the output may not be able to be parsed/round-tripped but it does give you full control when producing for instance HTML output.
escapeAttributes
- the new valueWhether empty elements are expanded from <tagName/> to <tagName></tagName>.
expandEmptyElements
- if true
, empty
elements will be represented by an opening tag
followed immediately by a closing tag.
Defaults to false
.Allows empty attributes to be removed from the generated markup.
omitEmptyAttributes
- if true
, empty
attributes will not be included in the resulting markup.
Defaults to false
.Allows null attributes to be removed from the generated markup.
omitNullAttributes
- if true
, null
attributes will not be included in the resulting markup.
If false
null attributes will be included in the
markup as empty strings regardless of the omitEmptyAttribute
setting. Defaults to false
