The GNUstep XML parser is a collection Objective-C classes
wrapping the C XML parsing library (libxml).
The underlying C library handles high performance parsing,
while the ObjectiveC classes provide ease of
use/integration.

- GNUstepBase/GSXML.h
Availability: Not in OpenStep/MacOS-X
The GSHTMLParser class is a simple subclass of
GSXMLParser which should parse reasonably well
formed HTML documents. If you wish to parse XHTML
documents, you should use GSXMLParser... the
GSHTMLParser class is for older 'legacy'
documents.
- Declared in:
- GNUstepBase/GSXML.h
Availability: Not in OpenStep/MacOS-X
You may create a subclass of this class to handle
incremental parsing of html documents... this is
provided for handling legacy documents, as modern
html documents should use xhtml, and for those you
should simply subclass
GSSAXHandler
- Declared in:
- GNUstepBase/GSXML.h
Availability: Not in OpenStep/MacOS-X
XML SAX Handler.
GSSAXHandler is a callback-based interface to
the
GSXMLParser
which operates in a similar (though not identical)
manner to SAX.
Each GSSAXHandler object is associated with a
GSXMLParser object. As parsing progresses,
the methods of the GSSAXHandler are invoked by the
parser, so the handler is able to deal with the
elements and entities being parsed.
The callback methods in the GSSAXHandler class do
nothing - it is intended that you subclass
GSSAXHandler and override them.
If you create a GSXMLParser passing nil
as the GSSAXHandler, the parser will parse data to
create a
GSXMLDocument
instance which you can then examine as a whole
... this is generally the preferred mechanism for
parsing as it permits the parser to validate
the parsed document againts a DTD, and your
software can then examine the document secure
in the knowledge that it contains the expected
structure. Use of a GSSAXHandler is
preferred for very large documents with
simple structure... in which case incremental
parsing is more efficient.

Availability: Not in OpenStep/MacOS-X
Converts a node type string to a numeric
constant which can be compared with the result
of the -type

is. Because this method is quite inefficient, you
should cache the numeric type returned and re-use
the cached value.

Return attributes and values as a dictionary
- (NSString*)
content;
Availability: Not in OpenStep/MacOS-X
Return node content as a string. This should return
meaningful information for text nodes and for
entity nodes containing only text nodes.
If
entity substitution was not enabled during parsing,
an element containing text may actually contain both
text nodes and entity reference nodes, in this case
you should not use this method to get the content of
the element, but should examine the child nodes of the
element individually and perform any entity
reference you need to do explicitly.
NB.
There are five standard entities which are
automatically substituted into the content
text rather than appearing as entity nodes in their
own right. These are '<', '>', ''', '"'
and '&'. If you with to receive content in which
these characters are represented by the original
entity escapes, you need to use the
-escapedContent
method.
- (NSString*)
description;
Availability: Not in OpenStep/MacOS-X
Returns a string representation of the node and all
its children (ie the XML text) or nil
if
the node does not have reasonable contents.

Return the document in which this node exists.
- (NSString*)
escapedContent;
Availability: Not in OpenStep/MacOS-X
This performs the same function as the
-content
method, but retains escaped character information
(the standard five entities <, >,
', ", and &) which
are normally replaced with their standard equivalents
(<, >, ', ", and &).

ignore non-element nodes such as whitespace text
separating elements.
- (

Returns the next element node, skipping past any
other node types (such as text nodes). If there is no
element node to be returned, this method returns
nil
.
NB. This method is not
available in java, as the method name conflicts
with that of java's Enumerator class.

propertiesAsDictionaryWithKeyTransformationSel: (SEL)keyTransformSel;
Availability: Not in OpenStep/MacOS-X
Return attributes and values as a dictionary, but
applies the specified selector to each key before
adding the key and value to the dictionary. The
selector must be a method of NSString taking no

probably not of much use elsewhere.
- (void)
setNamespace: (
GSXMLNamespace*)space;
Availability: Not in OpenStep/MacOS-X
Sets the namespace of the receiver to the value
specified.
Supplying a nil
namespace removes any namespace previously set or
any namespace that the node inherited from a parent
when it was created.
- (void)
setObject: (NSString*)value
forKey: (NSString*)key;
Availability: Not in OpenStep/MacOS-X
Set (or reset) an attribute carried by a node.

[n1 setObject: @"prop3" forKey: @"name3"];
- (
NSInteger)
type;

node types is to use this method and compare the
return value with a value you previously obtained
using the
+typeFromDescription:
method.

Availability: Not in OpenStep/MacOS-X
The XML parser object is the pivotal part of parsing an
XML document - it will either build a tree representing
the document (if initialized without a GSSAXHandler),
or will cooperate with a GSSAXHandler object to provide
parsing without the overhead of building a tree.
The parser may be initialized with an input source (in
which case it will expect to be asked to parse the
entire input in a single operation), or without. If
it is initialised without an input source, incremental
parsing can be done by feeding successive parts of
the XML document into the parser as NSData objects.

Method summary
+ (NSString*)
loadEntity: (NSString*)publicId
at: (NSString*)location;
Availability: Not in OpenStep/MacOS-X
This method controls the loading of external
entities into the system. If it returns an empty
string, the entity is not loaded. If it returns a
filename, the entity is loaded from that file.
If it returns nil
, the default entity
loading mechanism is used.
The default entity loading mechanism is to construct
a file name from the locationURL, by replacing all path
separators with underscores, then attempt to
locate that file in the DTDs resource directory of
the main bundle, and all the standard system
locations.
As a special case, the default loader examines the
publicID and if it is a GNUstep DTD, the loader
constructs a special name from the ID (by
replacing dots with underscores and spaces with
hyphens) and looks for a file with that name and
a '.dtd' extension in the GNUstep bundles.
NB. This method will only be called if there is no
SAX handler in use, or if the corresponding method in
the SAX handler returns nil
.

- Declared in:
- GNUstepBase/GSXML.h
- Conforms to:
- NSURLHandleClient
Availability: Not in OpenStep/MacOS-X
The GSXMLRPC class provides methods for constructing
and parsing XMLRPC method call and response documents
... so that calls may be constructed of standard
objects.
The correspondence between XMLRPC values and
Objective-C objects is as follows -
-
i4 (or
int) is an
NSNumber
other than a real/float or boolean.
-
boolean is an
NSNumber
created as a BOOL.
-
string is an
NSString
object.
-
double is an
NSNumber
created as a float or
double.
-
dateTime.iso8601 is an
NSDate
object.
-
base64 is an
NSData
object.
-
array is an
NSArray
object.
-
struct is an
NSDictionary
object.
If you attempt to use any other type of
object in the construction of an
XMLRPC document, the
[NSObject -description]
method of that object will be used to create a striong, and the resulting object will be encoded as an XMLRPC string element.
In particular, the names of members in a
struct must be strings, so if
you provide an
NSDictionary
object to represent a struct the keys of the dictionary will be converted to strings if necessary.
The class also provides a method for
making a synchronous XMLRPC method
call (with timeout), or an
asynchronous call in which
the call completion is handled by a
delegate.
You may also use the class to
implement an XMLRPC server, by
calling the
-parseMethod:params:
method to parse the data POSTed to your server, and -buildResponseWithParams:
(or -buildResponseWithFaultCode:andString:) to produce the data to be sent back to the client.
In order to simply make a synchronous
XMLRPC call to a server, all you
need to do is write code like:
GSXMLRPC *server = [[GSXMLRPC alloc] initWithURL: @"http://server/path"];
id result = [server makeMethodCall: name params: p timeout: 30];
Saying that you want to call the specified method
('name') on the server, passing the parameters
('p') and with a 30 second timeout.
If there
is a network or http-level error or a timeout, the
result will be an error string, otherwise it will be
an array (on success) or a dictionary containing the
fault details.

Initialise the receiver to make XMLRPC calls to
the specified url and (optionally) with the
specified SSL parameters.
The
url argument may be nil
, in
which case the receiver will be unable to make XMLRPC
calls, but can be used to parse incoming requests
and build responses.
If the SSL credentials are
non-nil, connections to the remote server will be
authenticated using the supplied certificate
so that the remote system knows who is contacting it.

nil
as
long as the call has not completed.
The call may be cancelled by calling the
-timeout:
method This
method
returns
YES
