<itemizedlist>
|

or has a corresponding end tag.

</para></listitem>
|

<listitem><para>
|
||||
There is exactly one root element. This element must contain
|
||||
all other elements in the document. Only comments, white
|
||||
space, and processing instructions may come after the close
|
||||
of the root element.
|
||||
</para></listitem>

<listitem><para>
|

All elements nest properly.

or double).

</itemizedlist>

|

<para>
|
||||
If the document has a DTD, and it strictly complies with that
|
||||
DTD, then the document is also considered <emphasis>valid</emphasis>.
|
||||
<command>&dhpackage;</command> is a non-validating parser --
|
||||
it does not check the DTD. However, it does support
|
||||
external entities (see the <option>-x</option> option).

<title>OPTIONS</title>
|
||||
|
||||
<para>
|
||||
When an option includes an argument, you may specify the argument either
|
||||
separately ("<option>-d</option> output") or concatenated with the
|
||||
option ("<option>-d</option>output"). <command>&dhpackage;</command>
|
||||
supports both.

||||

||||
<varlistentry>
|
||||
<term><option>-c</option></term>
|
||||
<listitem>
|
||||
<para>
|
||||
If the input file is well-formed and <command>&dhpackage;</command>
|
||||
doesn't encounter any errors, the input file is simply copied to
|
||||
the output directory unchanged.
|
||||
This implies no namespaces (turns off <option>-n</option>) and
|
||||
requires <option>-d</option> to specify an output file.

||||

||||

<term><option>-d output-dir</option></term>
|
||||
<listitem>
|
||||
<para>
|
||||
Specifies a directory to contain transformed
|
||||
representations of the input files.
|
||||
By default, <option>-d</option> outputs a canonical representation
|
||||
(described below).
|
||||
You can select different output formats using <option>-c</option>
|
||||
and <option>-m</option>.
|
||||
</para>
|
||||
<para>
|
||||
The output filenames will
|
||||
be exactly the same as the input filenames or "STDIN" if the input is
|
||||
coming from standard input. Therefore, you must be careful that the
|
||||
output file does not go into the same directory as the input
|
||||
file. Otherwise, <command>&dhpackage;</command> will delete the
|
||||
input file before it generates the output file (just like running
|
||||
<literal>cat < file > file</literal> in most shells).
|
||||
</para>
|
||||
<para>
|
||||
Two structurally equivalent XML documents have a byte-for-byte
|
||||
identical canonical XML representation.
|
||||
Note that ignorable white space is considered significant and
|
||||
is treated equivalently to data.

<literal>US-ASCII</literal>,

<para>

Normally <command>&dhpackage;</command> memory-maps the XML file

before parsing; this can result in faster parsing on many

platforms.
|

<option>-r</option> turns off memory-mapping and uses normal file
|
||||
IO calls instead.
|
||||
Of course, memory-mapping is automatically turned off
|
||||
when reading from standard input.
|
||||
</para>
|
||||
<para>
|
||||
Use of memory-mapping can cause some platforms to report
|
||||
substantially higher memory usage for
|
||||
<command>&dhpackage;</command>, but this appears to be a matter of
|
||||
the operating system reporting memory in a strange way; there is

not a leak in <command>&dhpackage;</command>.

</para>
|

<para>
|
||||
Non-validating parsers are not required to resolve external
|
||||
entities, or even expand entities at all.
|
||||
Expat always expands internal entities (?),
|
||||
but external entity parsing must be enabled explicitly.
|
||||
</para>
|
||||
<para>
|
||||
External entities are simply entities that obtain their
|
||||
data from outside the XML file currently being parsed.
|

</para>
|

<para>
|

This is an example of an internal entity:

</literallayout>
|

</para>
|

|

<literallayout>
|

<!ENTITY header SYSTEM "header-&vers;.xml"> (parsed)
|

<!ENTITY logo SYSTEM "logo.png" PNG> (unparsed)

|

<para>
|

<command>&dhpackage;</command> returns a 0 - noerr result,
|

even if the file is not well-formed. There is no good way for

a program to use <command>&dhpackage;</command> to quickly
|

check a file -- it must parse <command>&dhpackage;</command>'s
|
||||
standard output.
|

</para>
|

<para>
|
||||
The errors should go to standard error, not standard output.
|

</para>
|

<para>
|

There should be a way to get <option>-d</option> to send its

output to standard output rather than forcing the user to send
|

it to a file.

<para>

I have no idea why anyone would want to use the

me, I'd like to add this information to this manpage.
