17: .SH "DESCRIPTION"
18: .PP
19: The
20: \fBxmllint\fR
21: program parses one or more
22: XML
23: files, specified on the command line as
24: \fIXML\-FILE\fR
25: (or the standard input if the filename provided is
26: \fB\-\fR
27: ). It prints various types of output, depending upon the options selected. It is useful for detecting errors both in
28: XML
29: code and in the
30: XML
31: parser itself.
32: .PP
33: \fBxmllint\fR
34: is included in
35: \fBlibxml\fR(3).
