NAME
       xml-highlight - Highlight syntax in XML documents

SYNOPSIS
              xml-highlight [options] [<document>...]

DESCRIPTION
       The  xml-highlight tool adds syntax highlighting to program listings in
       an XML document.  By default this is accomplished by wrapping  detected
       syntax  in  XSL-FO inline elements with the proper namespace to allow a
       stylesheet to pass them through to the final FO processor.  The  actual
       elements used can be customized, however.

       To  enable  highlighting  on text in an element, include the processing
       instruction <?language ...?> in the element, where ... is the  name  of
       the language.

OPTIONS
       -c, --classes <classes>
              Use a custom class definitions file.

       -f, --overwrite
              Overwrite input XML file(s) instead of outputting to stdout.

       -h, -?, --help
              Show help/usage message.

       -s, --syntax <syntax>
              Use a custom syntax definitions file.

       --version
              Show version information.

       In addition, the following options allow configuration of the XML pars‐
       er:

       --dtdload
              Load the external DTD.

       --huge Remove any internal arbitrary parser limits.

       --net  Allow network access to load external DTD and entities.

       --noent
              Resolve entities.

       --xinclude
              Do XInclude processing.

       --xml-catalog <file>
              Use an XML catalog when resolving entities.   Multiple  catalogs
              may be loaded by specifying this option multiple times.

CLASS FILE FORMAT
       The  following  describes the format of the custom class file specified
       with -c.

   Classes
       Markup element: <classes>

       Attributes:

       · None

       Child elements:

       · <class>

   Class
       Represents a type of syntax and how it should be highlighted.  This el‐
       ement  can  also occur within the syntax element or within a particular
       language element, in which case it is specific to that language.

       Markup element: <class>

       Attributes:

       · id, the identifier of the class.

       Child elements:

       The element class contains one child element of  any  kind,  which  any
       matching syntax will be wrapped in to.

   Example custom classes file
              <classes xmlns:fo="http://www.w3.org/1999/XSL/Format">
              <class id="type">
              <fo:inline color="green"/>
              </class>
              <class id="control">
              <fo:inline color="blue"/>
              </class>
              <class id="string">
              <fo:inline color="red"/>
              </class>
              <class id="comment">
              <fo:inline color="pink"/>
              </class>
              </classes>

SYNTAX FILE FORMAT
       The  following describes the format of the custom syntax file specified
       with -s.

   Syntax
       Markup element: <syntax>

       Attributes:

       · None

       Child elements:

       · class

       · language

   Language
       Describes the syntax of a particular language.

       Markup element: <language>

       Attributes:

       · name, the identifier of the language.

       · caseInsensitive, indicates whether keywords are  case-insensitive  in
         this language, with one of the following values:

         · "no" - Keywords are case-sensitive (default)

         · "yes" - Keywords are case-insensitive

       Child elements:

       · <class>

       · <area>

       · <keyword>

   Area
       Matches a section of delimited text, such as strings, comments, etc.

       Markup element: <area>

       Attributes:

       · start, the opening delimiter.

       · end, the closing delimiter.

       · class, reference to the class element to use for this area.

       Child elements:

       If attribute class is not used, this element can contain one element of
       any kind, in which the text matching the area will be wrapped.

   Keyword
       Matches a particular keyword.

       Markup element: <keyword>

       Attributes:

       · match, the keyword to match.

       · class, reference to the class element to use for this keyword.

       Child elements:

       If attribute class is not used, this element can contain one element of
       any kind, in which the text matching the keyword will be wrapped.

   Example custom syntax file
              <syntax>
              <language name="c">
              <area start="&quot;" end="&quot;" class="string"/>
              <area start="/*" end="*/" class="comment"/>
              <keyword match="if" class="control"/>
              <keyword match="else" class="control"/>
              <keyword match="int" class="type"/>
              <keyword match="char" class="type"/>
              </language>
              </syntax>
