PROGRAM:
NAME
xml2po - program to create a PO-template file from a DocBook XML file and merge it back
into a (translated) XML file
SYNOPSIS
xml2po [OPTIONS] [XMLFILE]
DESCRIPTION
This manual page documents briefly the xml2po command.
xml2po is a simple Python program which extracts translatable content from free-form XML
documents and outputs gettext compatible POT files. Translated PO files can be turned into
XML output again.
It can work it´s magic with most "simple" tags, and for complicated tags one has to
provide a list of all tags which are "final" (that will be put into one "message" in PO
file), "ignored" (skipped over) and "space preserving".
OPTIONS
The program follows the usual GNU command line syntax, with long options starting with two
dashes (`-´). A summary of options is included below.
-a, --automatic-tags
Automatically decide if tags are to be considered "final" or not.
-k, --keep-entities
Don´t expand entities (default). See also the -e option.
-e, --expand-all-entities
Expand all entities (including SYSTEM ones).
-m, --mode=TYPE
Treat tags as type TYPE (default: docbook).
-o, --output=FILE
Print resulting text (XML while merging translations with "-p" or "-t" options, POT
template file while extracting strings, and translated PO file with "-r" option) to
the given FILE.
-p, --po-file=FILE
Specify a PO FILE containing translation and output XML document with translations
merged in.
-r, --reuse=FILE
Specify a translated XML document in FILE with the same structure to generate
translated PO file for XML document given on command line.
-t, --translation=FILE
Specify a MO file containing translation and output XML document with translations
merged in.
-u, --update-translation=LANG.po
Update a PO file using msgmerge.
-l, --language=LANG
Explicitly set language of the translation.
-h, --help
Show summary of options.
-v, --version
Show version of program.
EXAMPLES
Creating POT template files
To create a POT template book.pot from an input file book.xml, which consists of
chapter1.xml and chapter2.xml (external entities), run:
/usr/bin/xml2po -o book.pot book.xml chapter1.xml chapter2.xml
To expand entities use the -e option:
/usr/bin/xml2po -e -o book.pot book.xml
Creating translated XML files (merging back PO files)
After translating book.pot into LANG.po, merge the translations back by using -p option
for each XML file:
/usr/bin/xml2po -p LANG.po -o book.LANG.xml book.xml
/usr/bin/xml2po -p LANG.po -o chapter1.LANG.xml chapter1.xml
/usr/bin/xml2po -p LANG.po -o chapter2.LANG.xml chapter2.xml
If you used the -e option to expand entities, you should use it again to merge back the
translation into an XML file:
/usr/bin/xml2po -e -p LANG.po -o book.LANG.xml book.xml
Updating PO files
When base XML file changes, the real advantages of PO files come to surface. There are 2
ways to merge the translation. The first is to produce a new POT template file
(additionally use the -e if you decided earlier to expand entities). Afterwards run
msgmerge to merge the translation with the new POT file:
/usr/bin/msgmerge -o tmp.po LANG.po book.pot
Now rename tmp.po to LANG.po and update your translation. Alternatively, xml2po provides
the -u option, which does exactly these two steps for you. The advantage is, that it also
runs msgfmt to give you a statistical output of translation status (count of translated,
untranslated and fuzzy messages). Additionally use the -e if you decided earlier to expand
entities:
/usr/bin/xml2po -u LANG.po book.xml
