 | ###  . 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). |

 |       # 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. |
