Hello, There is a bug reported on the Alioth tracker against the Sgml module. I did not notice it before. Was there a notification on po4a-devel(a)lists.alioth? Otherwise, is there a way to get some notifications from the tracker? Then regarding the bug report: * I've already uploaded a simple fix for a typo reported in the bug report. * the SGML book uses a contrib and epigraph tag. Are those tags standards? Can I add them to the translate category? * for the main part of the bug report, I propose to escape '<', '>' and '&' to {PO4A-lt}, {PO4A-gt} and {PO4A-amp} before feeding nsgmls. And changing them back to the original in the cdata type. I also had some other issues with this PHP book: * around line 795, PO4A-beg/end are changed back to there SGML counterparts only if they appear at the beginning of a line. Why only at the beginning? This cause some PO4A-beg/end to be kept in the output document. * also, the content of the cdata is pushed, but the buffer is not flushed, so it can be pushed too early. In my patch, I appended the content of the cdata to $buffer. Should the content of cdata be verbatim? shouldn't it be translated? * also, I don't really understand what is done with the leading spaces and the added trailing '\n', but this is probably not an issue. * around line 535, & is changed to {PO4A-amp} if it is not the beginning of an entity. This uses: while ($origfile =~ /^(.*?)&([^;\s]*);(.*)$s/) { ... } this regex is too permissive. This cause the following line: ]]><![CDATA[&d_op=viewdownload&cid=79\">Web Installer... being changed in: ]]><![CDATA[_op=viewdownload=79\">Web Installer... I found the following grammar (for XML): http://www.w3.org/TR/REC-xml/#NT-Name It's probably too complicated (the Letter or Digit rules use a lot of Unicode chars). So I propose to only allow ASCII chars (with a non greedy match): while ($origfile =~ /^(.*?)&([A-Za-z_:][-_:.A-Za-z0-9]*?);(.*)$s/) { ... } * my last point: can anybody have a look at the sgmldiff between EN-Book.sgml and po4a-normalize.output? I'm highly incompetent regarding SGML and I based my analysis on po4a and sgmldiff outputs. So please stop me if any of the above statement is wrong. Attached is the patch I plan to commit this week. TIA, -- Nekral
