xmlpretty - XML pretty printer


xmlpretty [--options] [filename]


xmlpretty is the commandline interface to XML::Handler::YAWriter, acting as a tool to add
and remove pretty printing to XML files.

xmlpretty has several methods to add human readablitiy.

If you want to add readablity without adding so-called ignorable whitespace, use it in the
following way :

$ xmlpretty --AddHiddenNewline \
--AddHiddenAttrTab \
--CatchEmptyElement \
uglyfile.xml > prettyfile.xml

If you do not want to process the file further, but only want it human readable, add
visible whitespace to the file as follows :

$ xmlpretty --PrettyWhiteNewline \
--PrettyWhiteIndent \
--CatchEmptyElement \
uglyfile.xml > prettyfile.xml

You may use YAWriter to clean whitespace from XML documents. This may work in 99% of the
cases where you want to get rid of ignorable whitespace caused by the various forms of
pretty printing.

$ xmlpretty --NoWhiteSpace \
--NoComments \
--AddHiddenNewline \
--AddHiddenAttrTab \
--CatchEmptyElement \
prettyfile.xml > cleanfile.xml

Options are given in a gnu like --option idiom.

AddHiddenNewline boolean
Add hidden newline before ">"

AddHiddenAttrTab boolean
Add hidden tabulation for attributes

CatchEmptyElement boolean
Catch empty Elements, apply "/>" compression

CatchWhiteSpace boolean
Catch whitespace with comments

IsSGML boolean
This option will cause start_document, processing_instruction and doctype_decl to
appear as SGML. The SGML is still well-formed of course, if your SAX events are well-

NoComments boolean
Supress Comments

NoDTD boolean
Supress DTD

NoPI boolean
Supress Processing Instructions

NoProlog boolean
Supress <?xml ... ?> Prolog

NoWhiteSpace boolean
Supress WhiteSpace to clean documents from prior pretty printing.

PrettyWhiteIndent boolean
Add visible indent before any eventstring

PrettyWhiteNewline boolean
Add visible newlines before any eventstring

SAX1 boolean (not yet implemented)
Output only SAX1 compilant eventstrings

Automatic recoding between 8bit and 16bit does not yet work correctly !

I have Perl-5.6 at home and here I can specify "use utf8;" in the right places to make
recoding work. But I dislike saying "use 5.00555;" because many systems run 5.00503.
