xgettext and XML files - extracting strings

[Jamenson Espindula]

Hi.
Congratulations for the excellent software "GNU gettext"!

I just started learning "xgettext" from "GNU gettext".

There is a XML file (line numbers are not in original):

 = = = Begin XML file = = =

     1 <?xml version="1.0" encoding="ISO-8859-1"?>
     2 <!DOCTYPE bookinfo PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"
     3   "http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd"; [
     4   <!ENTITY % general-entities SYSTEM "../general.ent">
     5   %general-entities;
     6 ]>

I tried to extract the strings. The POT file produced is:

 = = = Begin "bookinfo.pot" file = = =

As you can see, lines 45 and 46 were skipped.

Here are the "ITS rules" and the "locator" files that are in effect:

 = = = Begin "lfs.its" file = = =

<?xml version="1.0"?>
<its:rules xmlns:its="http://www.w3.org/2005/11/its"; version="1.0">
  <its:translateRule selector="/book" translate="no"/>
  <its:translateRule selector="/bookinfo" translate="no"/>
  <its:translateRule selector="//title" translate="yes"/>
  <its:translateRule selector="//subtitle" translate="yes"/>
  <its:translateRule selector="//authorgroup" translate="yes"/>
  <its:translateRule selector="//copyright" translate="yes"/>
  <its:translateRule selector="//legalnotice" translate="yes"/>
  <its:translateRule selector="//message/p[@translatable = 'no']"
    translate="no"/>
</its:rules>

 = = = End "lfs.its" file = = =

 = = = Begin "lfs.loc" file = = =

<?xml version="1.0"?>
<locatingRules>
  <locatingRule name="LFS" pattern="*.xml" target="lfs.its"/>
</locatingRules>

 = = = End "lfs.loc" file = = =

Why were lines 45 and 46 skipped?

Thank you.
