OpenOffice.org in the Limelight

How CHIP Special Linux uses OpenOffice.org Writer as an editorial tool in a multiplatform publishing house.
HTML Format

Obtaining proper documents in HTML format is slightly more difficult. StarWriter and OpenOffice.org Writer produce sophisticated HTML, as shown in Figure 2. You can convert this HTML, however, by using a simple Perl script. I call mine soffice2html. At the beginning of the script, you should instruct it to replace line endings by spaces, like this:


s/\n/ /;

Next, you can replace some elements of the code with different ones. For example, using the commands:


s/<(\/?)B>/<$1STRONG>/g;
s/<(\/?)I>/<$1EM>/g;

you can replace all <B> ... </B> and <I> ... </I> tag pairs with <STRONG> ... </STRONG> and <EM> ... </EM> tag pairs, so bold and italic is noted according to established standards. You then can remove unwanted tags, such as:


s/<EM><EM>/<EM>/g;
s/<\/EM><\/EM>/<\/EM>/g;

After this, it is good idea to restore some line endings. Simple commands such as:


s/(.+?)</$1\n</g;
s/>(.+?)/>\n$1/g;

put the marks of the line end before and after each HTML tag. To make your script more professional, you can add the finishing touch by using the command:


print OUT "<!-- ", "soffice2html: ",
          scalar localtime, " -->\n";

This adds a comment to the processed HTML file, which is something like:


<!-- soffice2html: Wed Jul 23 17:34:35 2003 -->

Now, if you start with document.sxw and export it to document.html, you should process the latter one using the command soffice2html document.html (Figure 3). Filtering HTML files in this way produces better—that is, more standardized and more readable—code and from 15%–40% smaller files. The current version of the ooo-macro bundle includes the soffice2html script.

To produce a simple Macintosh text file from a document, you should save it in the Text Encoded file type that uses the appropriate character set. For Polish documents, for example, the valid set is Eastern Europe.

This method of exporting is good enough for common tasks, but it's not so good for typographic purposes. Our articles often need to use symbols for keystrokes when discussing specific tasks and other special characters. When you use the standard method to produce Macintosh text files, you lose all those characters. To keep them, you need a macro to convert the characters from UTF-8 to the Macintosh codepage. The appropriate macro, recode_utf_8_to_apple_macintosh, is a part of the ooo-macro bundle.

In order to produce a text file using the above-mentioned macro, run it and then save the document as a Text Encoded file type by using System character set and CR paragraph breaks. The file includes information that makes the typesetter's job faster and easier.

In the Limelight

Using OpenOffice.org Writer as an editorial tool allows you to process documents and share them among authors, proofreaders and typesetters in a way that is transparent for everyone involved. You need only Writer, some TrueType fonts, a small bundle of macros and the Perl script for preparing nice HTML files.

Are the Perl scripts available?

Hobgoblin's picture

Interesting reading - I was particularly interested in the way that 'clean' HTML can be obtained from the raw HTML output of Ooo writer. Are the Perl scripts available?

TIA

Anonymous's picture

It looks like these perl scripts manipulate tags using regular expressions. There are too many edge cases for this to be a good idea. Much better would be to properly parse the HTML, tidy it and walk the DOM tree to remove unwanted elements. The HTML section at CPAN looks like a good place to start doing that. Mind you, there are also interfaces to manipulate OOo documents directly. Good luck, happy hacking!

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
