- .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\&.
