|
|
|
|
|
|
The TQXmlNamespaceSupport class is a helper class for XML
|
|
readers which want to include namespace support.
|
|
|
|
<p>
|
|
|
|
<p> You can set the prefix for the current namespace with <a href="#setPrefix">setPrefix</a>(),
|
|
and get the list of current prefixes (or those for a given URI)
|
|
with <a href="#prefixes">prefixes</a>(). The namespace URI is available from <a href="#uri">uri</a>(). Use
|
|
<a href="#pushContext">pushContext</a>() to start a new namespace context, and <a href="#popContext">popContext</a>()
|
|
to return to the previous namespace context. Use <a href="#splitName">splitName</a>() or
|
|
<a href="#processName">processName</a>() to split a name into its prefix and local name.
|
|
<p> See also the <a href="xml.html#sax2Namespaces">namespace description</a>.
|
|
<p>See also <a href="xml-tools.html">XML</a>.
|
|

|
<hr><h2>Member Function Documentation</h2>
|
|
<h3 class=fn><a name="TQXmlNamespaceSupport"></a>TQXmlNamespaceSupport::TQXmlNamespaceSupport ()
|
|
</h3>
|
|
Constructs a TQXmlNamespaceSupport.
|
|
|
|
<h3 class=fn><a name="~TQXmlNamespaceSupport"></a>TQXmlNamespaceSupport::~TQXmlNamespaceSupport ()
|
|
</h3>
|
|
Destroys a TQXmlNamespaceSupport.
|
|
|
|
<h3 class=fn>void <a name="popContext"></a>TQXmlNamespaceSupport::popContext ()
|
|
</h3>
|
|
Reverts to the previous namespace context.
|
|
<p> Normally, you should pop the context at the end of each XML
|
|
element. After popping the context, all namespace prefix mappings
|
|
that were previously in force are restored.
|
|
<p> <p>See also <a href="#pushContext">pushContext</a>().
|
|
|
|
<h3 class=fn><a href="tqstring.html">TQString</a> <a name="prefix"></a>TQXmlNamespaceSupport::prefix ( const <a href="tqstring.html">TQString</a> & uri ) const
|
|
</h3>
|
|
Returns one of the prefixes mapped to the namespace URI <em>uri</em>.
|
|
<p> If more than one prefix is currently mapped to the same URI, this
|
|
function makes an arbitrary selection; if you want all of the
|
|
prefixes, use <a href="#prefixes">prefixes</a>() instead.
|
|
<p> Note: to check for a default prefix, use the <a href="#uri">uri</a>() function with
|
|
an argument of "".
|
|
|
|
<h3 class=fn><a href="tqstringlist.html">TQStringList</a> <a name="prefixes"></a>TQXmlNamespaceSupport::prefixes () const
|
|
</h3>
|
|
Returns a list of all the prefixes currently declared.
|
|
<p> If there is a default prefix, this function does not return it in
|
|
the list; check for the default prefix using <a href="#uri">uri</a>() with an
|
|
argument of "".
|
|
<p> Note that if you want to iterate over the list, you should iterate
|
|
over a copy, e.g.
|
|
<pre>
|
|
<a href="tqstringlist.html">TQStringList</a> list = myXmlNamespaceSupport.prefixes();
|
|
TQStringList::iterator it = list.<a href="tqvaluelist.html#begin">begin</a>();
|
|
while ( it != list.<a href="tqvaluelist.html#end">end</a>() ) {
|
|
myProcessing( *it );
|
|
++it;
|
|
}
|
|
</pre>
|
|
|
|
|
|
<h3 class=fn><a href="tqstringlist.html">TQStringList</a> <a name="prefixes-2"></a>TQXmlNamespaceSupport::prefixes ( const <a href="tqstring.html">TQString</a> & uri ) const
|
|
</h3>
|
|
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|
<p> Returns a list of all prefixes currently declared for the
|
|
namespace URI <em>uri</em>.
|
|
<p> The "xml:" prefix is included. If you only want one prefix that is
|
|
mapped to the namespace URI, and you don't care which one you get,
|
|
use the <a href="#prefix">prefix</a>() function instead.
|
|
<p> Note: the empty (default) prefix is never included in this list;
|
|
to check for the presence of a default namespace, use <a href="#uri">uri</a>() with
|
|
an argument of "".
|
|
<p> Note that if you want to iterate over the list, you should iterate
|
|
over a copy, e.g.
|
|
<pre>
|
|
<a href="tqstringlist.html">TQStringList</a> list = myXmlNamespaceSupport.prefixes( "" );
|
|
TQStringList::Iterator it = list.<a href="tqvaluelist.html#begin">begin</a>();
|
|
while( it != list.<a href="tqvaluelist.html#end">end</a>() ) {
|
|
myProcessing( *it );
|
|
++it;
|
|
}
|
|
</pre>
|
|
|
|
|
|
<h3 class=fn>void <a name="processName"></a>TQXmlNamespaceSupport::processName ( const <a href="tqstring.html">TQString</a> & qname, bool isAttribute, <a href="tqstring.html">TQString</a> & nsuri, <a href="tqstring.html">TQString</a> & localname ) const
|
|
</h3>
|
|
Processes a raw XML 1.0 name in the current context by removing
|
|
the prefix and looking it up among the prefixes currently
|
|
declared.
|
|
<p> <em>qname</em> is the raw XML 1.0 name to be processed. <em>isAttribute</em>
|
|
is TRUE if the name is an attribute name.
|
|
<p> This function stores the namespace URI in <em>nsuri</em> (which will be
|
|
set to <a href="tqstring.html#TQString-null">TQString::null</a> if the raw name has an undeclared prefix),
|
|
and stores the local name (without prefix) in <em>localname</em> (which
|
|
will be set to TQString::null if no namespace is in use).
|
|
<p> Note that attribute names are processed differently than element
|
|
names: an unprefixed element name gets the default namespace (if
|
|
any), while an unprefixed element name does not.
|
|
|
|
<h3 class=fn>void <a name="pushContext"></a>TQXmlNamespaceSupport::pushContext ()
|
|
</h3>
|
|
Starts a new namespace context.
|
|
<p> Normally, you should push a new context at the beginning of each
|
|
XML element: the new context automatically inherits the
|
|
declarations of its parent context, and it also keeps track of
|
|
which declarations were made within this context.
|
|
<p> <p>See also <a href="#popContext">popContext</a>().
|
|
|
|
<h3 class=fn>void <a name="reset"></a>TQXmlNamespaceSupport::reset ()
|
|
</h3>
|
|
Resets this namespace support object ready for reuse.
|
|
|
|
<h3 class=fn>void <a name="setPrefix"></a>TQXmlNamespaceSupport::setPrefix ( const <a href="tqstring.html">TQString</a> & pre, const <a href="tqstring.html">TQString</a> & uri )
|
|
</h3>
|
|
This function declares a prefix <em>pre</em> in the current namespace
|
|
context to be the namespace URI <em>uri</em>. The prefix remains in
|
|
force until this context is popped, unless it is shadowed in a
|
|
descendant context.
|
|
<p> Note that there is an asymmetry in this library. <a href="#prefix">prefix</a>() does not
|
|
return the default "" prefix, even if you have declared one; to
|
|
check for a default prefix, you must look it up explicitly using
|
|
<a href="#uri">uri</a>(). This asymmetry exists to make it easier to look up prefixes
|
|
for attribute names, where the default prefix is not allowed.
|
|
|
|
<h3 class=fn>void <a name="splitName"></a>TQXmlNamespaceSupport::splitName ( const <a href="tqstring.html">TQString</a> & qname, <a href="tqstring.html">TQString</a> & prefix, <a href="tqstring.html">TQString</a> & localname ) const
|
|
</h3>
|
|
Splits the name <em>qname</em> at the ':' and returns the prefix in <em>prefix</em> and the local name in <em>localname</em>.
|
|
<p> <p>See also <a href="#processName">processName</a>().
|
|
|
|
<h3 class=fn><a href="tqstring.html">TQString</a> <a name="uri"></a>TQXmlNamespaceSupport::uri ( const <a href="tqstring.html">TQString</a> & prefix ) const
|
|
</h3>
|
|
Looks up the prefix <em>prefix</em> in the current context and returns
|
|
the currently-mapped namespace URI. Use the empty string ("") for
|
|
the default namespace.
