.SH "NAME"
tv_merge \- Merge (combine) two XMLTV files.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
tv_merge \-i \s-1FILE\s0 \-m \s-1FILE\s0 \-o \s-1FILE\s0
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Read \s-1XMLTV\s0 listings from two files and merge them together.
Unlike tv_cat (which just joins files) this will update (add/replace/delete)
the origin \s-1XMLTV\s0 file with channels and programmes contained in the second
file.
.PP
It works with multiple channels, and will insert any new programmes
and delete any overlapping programmes.
.PP
\&\fB\s-1IMPORTANT\s0\fR
The input files must be pre-sorted into datetime within channel order
by using the \*(L"\-\-by\-channel\*(R" option to tv_sort
  e.g. tv_sort \-\-by\-channel \-\-output \s-1FILE  FILE\s0
.PP
All programmes must have start and stop times.
.PP
(Note: Programmes in the merged-in file \fIreplace\fR any in the master file,
i.e. data are not updated \fIwithin\fR programmes)
.PP
This program uses XML::TreePP which doesn't write <\s-1DOCTYPE\s0> definitions in the
output file. If you need to add a suitable <\s-1DOCTYPE\s0> tag then use the \-t parameter.
  e.g. tv_merge \-i \s-1FILE\s0 \-m \s-1FILE\s0 \-o \s-1FILE\s0 \-t
.SH "EXAMPLE"
.IX Header "EXAMPLE"
Use \f(CW\*(C`tv_merge \-i master.xml \-m newadditions.xml \-o newmaster.xml\*(C'\fR to
merge all channels/programmes in \fInewadditions.xml\fR.
