<span class="application">xmlcatalog</span> is a command line application
allowing users to monitor and manipulate <span class="acronym">XML</span> and
<span class="acronym">SGML</span> catalogs. It is included in
<span class="application">libxml2</span>.
</p><p>
Its functions can be invoked from a single command from the command line,
or it can perform multiple functions in interactive mode. It can operate
on both <span class="acronym">XML</span> and <span class="acronym">SGML</span> files.
</p></div><div class="refsect1" lang="en"><a name="cloptions"></a><h2>Command Line Options</h2><div class="variablelist"><dl><dt><span class="term"><tt class="option">--shell</tt> <i class="replaceable"><tt>filename</tt></i></span></dt><dd>
Run a shell
allowing interactive queries on catalog file
<i class="replaceable"><tt>filename</tt></i>.
</dd><dt><span class="term"><tt class="option">--create</tt> <i class="replaceable"><tt>filename</tt></i></span></dt><dd>
Create a new
<span class="acronym">XML</span> catalog. Outputs to stdout, ignoring
<i class="replaceable"><tt>filename</tt></i> unless <tt class="option">--noout</tt> is
used, in which case it creates a new catalog file
<i class="replaceable"><tt>filename</tt></i>.
</dd><dt><span class="term"><tt class="option">--add</tt> <i class="replaceable"><tt>'type'</tt></i> <i class="replaceable"><tt>'orig'</tt></i> <i class="replaceable"><tt>'replace'</tt></i> <i class="replaceable"><tt>filename</tt></i></span></dt><dd><p>
Add an entry to catalog file
<tt class="filename">filename</tt>. <i class="replaceable"><tt>type</tt></i>
indicates the type of entry. Possible types are 'public', 'system',
'rewriteSystem', 'delegatePublic', 'delegateSystem'amd
'rewriteURI'. <i class="replaceable"><tt>'orig'</tt></i> is the original
reference to be replaced, and <i class="replaceable"><tt>'replace'</tt></i>
is the <span class="acronym">URI</span> of the replacement entity to be
used. The <tt class="option">--add</tt> option will not overwrite
<i class="replaceable"><tt>filename</tt></i>, outputing to stdout, unless
<tt class="option">--noout</tt> is used. The <tt class="option">--add</tt> will
always take three parameters even if some of the
<span class="acronym">XML</span> catalog constructs will have only a single
argument.
</p><p>
If the <tt class="option">--add</tt> option is used following the
<tt class="option">--sgml</tt> option, only a single argument, a
<i class="replaceable"><tt>filename</tt></i>, is used. This is used to add
the name of a catalog file to an <span class="acronym">SGML</span>
supercatalog, a file that contains references to other included
<span class="acronym">SGML</span> catalog files.
</p></dd><dt><span class="term"><tt class="option">--del</tt> <i class="replaceable"><tt>'values'</tt></i> <i class="replaceable"><tt>filename</tt></i></span></dt><dd>
Remove entries from the catalog file
<i class="replaceable"><tt>filename</tt></i> matching
<i class="replaceable"><tt>'values'</tt></i>. The <tt class="option">--del</tt> option
will not overwrite <i class="replaceable"><tt>filename</tt></i>, outputing to
stdout, unless <tt class="option">--noout</tt> is used.
</dd><dt><span class="term"><tt class="option">--noout</tt></span></dt><dd>
Save output to the named file rather than
outputing to stdout.
