.SH "DESCRIPTION"
.PP
The
\fBne_xml_parse_response\fR
function reads an HTTP response body and processes it using the given XML parser\&. The function must be called
\fBne_begin_request\fR
has returned successfully for the request, and then invokes
\fBne_read_response_block\fR
until the entire response body has been read\&. On successful return,
\fBne_end_request\fR
must be called to finalise response processing\&.
.PP
The
\fBne_xml_dispatch_request\fR
and
\fBne_xml_dispatchif_request\fR
functions is equivalent to calling
ne_request_dispatch
to dispatch an HTTP request and process the response, parsing the response body using the given XML parser under certain conditions:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
For
\fBne_xml_dispatch_request\fR, any
2xx
class response with an XML content\-type\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
For
\fBne_xml_dispatchif_request\fR, if the
\fIacceptor\fR
callback returns non\-zero, and the response uses an XML content\-type\&.
.RE
.sp
In both cases, the rules in
\m[blue]\fBRFC 7303\fR\m[]\&\s-2\u[1]\d\s+2
are followed to identify XML content\-types, that is
text/xml,
application/xml, or any other content\-type ending in a
+xml
suffix\&. The
\fIuserdata\fR
parameter is passed to the
\fIacceptor\fR
function\&.
.PP
For all three functions:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
the XML parser is invoked repeatedly until the end of the document is reached\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
if an error occurs during XML parsing, the session error string is set to describe the parse error, and the connection is terminated without continuing to process the response\&.\&.
.RE
.sp
.SH "RETURN VALUE"
.PP
All functions documented here return zero on success, or an
NE_* error code
on failure\&.
.SH "HISTORY"
.PP
\fBne_xml_dispatchif_request\fR
is available in neon 0\&.36\&.0 and later\&.
