###
### converts input in TEI P5 format (https://www1.ids-mannheim.de/kl/projekte/korpora/textmodell.html)
### into output in KorAP-XML format (https://github.com/KorAP/KorAP-XML-Krill -> 'KorAP-XML document')
###
### input restrictions:
###
### . utf8 encoded
### . TEI P5 formatted input with certain restrictions:
### . mandatory: text-header with integrated textsigle, text-body
### . optional: corp-header with integrated corpsigle, doc-header with integrated docsigle
###
### . all tokens inside the primary text (inside $data) may not be newline seperated, because newlines
### are removed (see below: 'inside text body') and a conversion of newlines into blanks between 2 tokens
### could lead to additional blanks, where there should be none (e.g.: punctuation characters like ',' or
### '.' should not be seperated from their predecessor token).
### - see also '~ whitespace handling ~'
###
### . POS and MSD inline annotations handling (see below: expected format)
### ...
###
### notes on the output:
###
### . zip file output (default on stdout) with utf8 encoded entries (which together form the KorAP-XML format)
### ...

# the 3rd form of nodes, next to text-nodes (XML_READER_TYPE_TEXT) and tag-nodes (XML_READER_TYPE_ELEMENT) are nodes
# of the type 'XML_READER_TYPE_SIGNIFICANT_WHITESPACE'
#
# when modifiying the above example (at the top of this sub) by inserting an additional blank between '</node1>' and '<node2>',
# the output for '$data->[2]->[0]->[5]->[1]->[1]' becomes a blank (' ') and it's type is '14' (see manpage of XML::LibXML::Reader):

} elsif ( $e->[0] == XML_READER_TYPE_TEXT || $e->[0] == XML_READER_TYPE_SIGNIFICANT_WHITESPACE ){
# notes on ~ whitespace related issue ~ (see below source code)
#
# example: '... <head type="main"><s>Campagne in Frankreich</s></head><head type="sub"> <s>1792</s> ...'
#
# Two text-nodes should normally be separated by a blank. In the above example, that would be the 2 text-nodes
# 'Campagne in Frankreich' and '1792', which are separated by the whitespace-node ' '.
#
# Assumed, that the above example marks the general case, then the text-node 'Campagne in Frankreich' leads to the
# setting of '$add_one' to 1, so that when opening the 2nd 'head'-tag and setting it's from-index, it gets the right
# offset, which is the start-index of '1792'.
#
# To check, that the above consideration holds, we save the from-index of a read whitespace-node into the hash %ws.
# By this, it can be checked when closing a tag, if the 'non-tag'-node (text or whitespace) before the last 'non-tag'-
# node was actually a whitespace-node ($ws{ $fval - 1 }).
#
# For whitespace-nodes, also $add_one has to be set to 0, so when opening the next tag (in the above example the 2nd
# 's'-tag), no additional 1 is added, because this was already done by the whitespace-node itself (by incrementing the
# variable $dl).
#
# Now, what happens, when 2 text-nodes are not seperated by a whitespace-node (blank)? (e.g.: <w>Augen<c>,</c></w>)
#
# In this case, the falsely increased from-value has to be decreased again by 1 when closing the referring tag
# (...$fval - 1; # recorrect).
#
# Comparing the 2 examples '<w>fu</w> <w>bar</w>' and '<w>fu</w><w> </w><w>bar</w>' (even though, the 2nd one makes less
# sense, because of '<w> </w>'), in both the ' ' is handled as a whitespace-node (XML_READER_TYPE_SIGNIFICANT_WHITESPACE).
#
# So the from-index of the 2nd w-tag (in the second example) would refer to 'bar', which may not have been the intention
# (even, if '<w> </w>' doesn't make a lot of sense). TODO: could this be a bug, which needs to be fixed?
#
# Empty tags also cling to the next text-token - e.g. in '...<w>tok1</w> <w>tok2</w><a><b/></a><w>tok3</w>...' the from-
# and to-indizes for the tags 'a' and 'b' are both 9, which is the start-index of the token 'tok3'.

=head1 NAME
tei2korapxml - Conversion of TEI P5 based formats to KorAP-XML
=head1 SYNOPSIS
cat corpus.i5.xml | tei2korapxml > corpus.korapxml.zip
=head1 DESCRIPTION
C<tei2korapxml> is a script to convert TEI P5 and I5 based documents
to the KorAP-XML format. If no specific input is defined, data is
read from C<STDIN>. If no specific output is defined, data is written
to C<STDOUT>.
This program is usually called from inside another script.
=head1 INSTALLATION
C<tei2korapxml> requires L<libxml2-dev> bindings to build. When
these bindings are available, the preferred way to install the script is
to use L<cpanm|App::cpanminus>.
$ cpanm https://github.com/KorAP/KorAP-XML-TEI.git
In case everything went well, the C<tei2korapxml> tool will
be available on your command line immediately.
Minimum requirement for L<KorAP::XML::TEI> is Perl 5.16.
=head1 OPTIONS
=over 2
=item B<--base|-b>
The base directory for output. Defaults to C<.>.
=item B<--help|-h>
Print help information.
=item B<--version|-v>
Print version information.
