public class QXmlNamespaceSupport
The QXmlNamespaceSupport
class is a helper class for XML readers which want to include namespace support. You can set the prefix for the current namespace with setPrefix()
, and get the list of current prefixes (or those for a given URI) with prefixes()
. The namespace URI is available from uri()
. Use pushContext()
to start a new namespace context, and popContext()
to return to the previous namespace context. Use splitName()
or processName()
to split a name into its prefix and local name.

Method Detail |

public final void popContext()
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.
pushContext()
.
public final java.lang.String prefix(java.lang.String arg__1)
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 prefixes()
instead.
Note: to check for a default prefix, use the uri()
function with an argument of "".
setPrefix()
.
public final java.util.List prefixes()
If there is a default prefix, this function does not return it in the list; check for the default prefix using uri()
with an argument of "".
public final java.util.List prefixes(java.lang.String arg__1)
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 prefix()
function instead.
Note: The empty (default) prefix is never included in this list; to check for the presence of a default namespace, call uri()
with "" as the argument.
public final void pushContext()
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.
popContext()
.
public final void reset()
public final void setPrefix(java.lang.String arg__1, java.lang.String arg__2)
Note that there is an asymmetry in this library. prefix()
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 uri()
. This asymmetry exists to make it easier to look up prefixes for attribute names, where the default prefix is not allowed.
prefix()
.
public final java.lang.String uri(java.lang.String arg__1)
public final QXmlNamespaceSupport.ProcessedName processName(java.lang.String qname, boolean isAttribute)
qname is the raw XML 1.0 name to be processed. isAttribute is true if the name is an attribute name.
Note that attribute names are processed differently than element names: an unprefixed element name gets the default namespace (if any), while an unprefixed attribute name does not.
public final QXmlNamespaceSupport.SplitName splitName(java.lang.String qname)
public QXmlNamespaceSupport clone()
