- !!HOW TO USE OPENOFFICE FILES IN A GENERATOR IN COCOON.
+ Pech gehabt! OpenOffice und Cocoon desch geht net.
- Author: [Yves Vindevogel|mailto:yves.vindevogel@implements.be]
- \\Date: 2003-03-14
- ----
- Hi all,
- 
- I think I got a solution to use __OpenOffice (Writer) files as a generator in Cocoon__.
- 
- First of all, thanks to [Conal Tuohy|Con] and [Upayavira] for pointing me at some very important
details.
- 
- Okay, what I did ....
- 
- !1. files and folders
- My cocoon folder looks like this:
- {{{
- cocoon/resources/entities
- cocoon/implements/sxw
- cocoon/implements/xsl
- cocoon/implements/....
- }}}
- 
- The sitemap for the Implements site is mounted as a submap of the sitemap in
- the /cocoon directory.
- 
- I've got the file "test.sxw" in my directory /implements/sxw \\
- I've got the file "html.oowriter.xsl" in my directory /implements/xsl \\
- I've got the files from, in my case opt/OpenOffice.org1.0/share/dtd/officedocument/1_0 \\
- (the DTDs from OpenOffice) copied to the folder /cocoon/resources/entities \\
- I've copy the files 'common.xsl  style_inlined.xsl  table_cells.xsl    table_rows.xsl
- global_document.xsl  main_html.xsl      style_header.xsl    style_mapping.xsl  table_columns.xsl
 table.xsl' from $OO_HOME/share/xslt/xhtml in my directory /implements/xsl \\
- And edit the 'main_html.xsl':\\
- a. set the following variables\\
-     <xsl:variable name="office:meta-file"           select="/office:document/office:document-meta"/>\\
-     <xsl:variable name="office:styles-file"         select="/office:document/office:document-styles"/>\\
-     <xsl:variable name="office:font-decls"          select="$office:styles-file/office:font-decls"/>\\
-     <xsl:variable name="office:styles"              select="$office:styles-file/office:styles"/>\\
- b. edit all '/*/office:body' entries to '/office:document/*/office:body', \\
-             all '$office:meta-file/*' to '$office:meta-file' \\
- in all the .xsl files, edit:\\
-             all '/*/office:body'  to '/office:document/*/office:body'\\
- Edit the style_headers.xsl:\\
- edit the\\
-     <xsl:template name='create-css-styleheader'>\\
-         <xsl:comment>\\
-             <xsl:text>The CSS style header method for setting styles</xsl:text>\\
-         </xsl:comment>\\
-         <xsl:element name="style">\\
-             <xsl:attribute name="type">text/css</xsl:attribute>\\
-             <xsl:comment>\\
-                 <xsl:text>\\
-                     
-                 </xsl:text>\\
- ...\\
- to\\
-     <xsl:template name='create-css-styleheader'>\\
-         <xsl:comment>\\
-             <xsl:text>The CSS style header method for setting styles</xsl:text>\\
-         </xsl:comment>\\
-         <xsl:element name="style">\\
-             <xsl:attribute name="type">text/css</xsl:attribute>\\
-             <xsl:comment>\\
-                 <xsl:text>\\
-                     BODY { background-repeat: no-repeat }\\
-                 </xsl:text>\\
- ...\\
- 
- !2. Sitemap
- This is my sitemap (well, the part for OO)
- 
- {{{
- <map:match pattern="sxw/*.html">
-   <map:aggregate element="office:document">
-     <map:part src="jar:http://web/implements/{1}.sxw!/content.xml"/>
-     <map:part src="jar:http://web/implements/{1}.sxw!/meta.xml"/>
- <!-- additional for styles -->
-     <map:part src="jar:http://web/implements/sxw/{1}.sxw!/styles.xml"/>
-   </map:aggregate>
- <!-- for using the standard OO transformation -->
-      <map:transform src="xsl/main_html.xsl"> 
-       <map:parameter name="metaFileURL" value="http://web/implements/sxw/{1}/meta.xml"/>
-       <map:parameter name="stylesFileURL" value="http://web/implements/sxw/{1}/styles.xml"/>
-       <map:parameter name="absoluteSourceDirRef" value="http://web/implements/sxw/{1}.sxw"/>
-       <map:parameter name="jaredRootURL" value="http://web/implements/sxw/{1}"/>
-      </map:transform>
- 
- <!--  Uncomment this, and comment previous if you want to use html.oowriter.xsl insead
of standard OO transformation
-    <map:transform src="xsl/html.oowriter.xsl"/> -->
-   <map:serialize type="html"/>
- </map:match>
- <map:match pattern="*.sxw">
-   <map:read src="{1}.sxw" mime-type="application/zip"/>
- </map:match>
- <!-- additional for xml reading -->
-     <map:match pattern="sxw/*/**.xml">
-      <map:read src="jar:http://web/implements/sxw/{1}.sxw!/{2}.xml" mime-type="text/plain"/>
-     </map:match>
- <!-- additional for images -->
-     <map:match pattern="sxw/*/Pictures/*.png">
-      <map:read src="jar:http://web/implements/sxw/{1}.sxw!/Pictures/{2}.png" mime-type="image/png"/>
-     </map:match>
- 
-     <map:match pattern="sxw/*/**.xml">
-      <map:read src="jar:http://10.10.5.100/implements/sxw/{1}.sxw!/{2}.xml" mime-type="text/plain"/>
-     </map:match>
- 
-     <map:match pattern="sxw/*.sxw">
-      <map:read src="sxw/{1}.sxw" mime-type="application/zip"/>
-     </map:match>
- 
- }}}
- 
- The basic element is this one is the "jar:http://" thing.  Thanks to Conal for
- pointing me to this.  OpenOffices uses a kind of zip file to store its files
- in.  The Jar: protocol is able to read those zips straight away.  Conal made
- a wiki page for this:
- \\[JarProtocolExample]
- 
- The only problem is the need for a "http://web/....".
- \\You need to specify the full path, the Jar: protocol does not work with the cocoon sitemap.
- 
- His wiki page shows the <map:read>, which works fine.  You can read whatever you
- want from the zip file.
- 
- !3. Generator
- I went further: I wanted to use the content.xml in that zip in a generator.
- \\So I changed the <map:read> into <map:generate>
- \\This results in an error:
- 
- {{{
- message File "jar:http://web/implements/test.sxw!/office.dtd" not found.
- description org.apache.cocoon.ProcessingException: 
- Failed to execute pipeline.: org.xml.sax.SAXParseException: 
- File "jar:http://web/implements/test.sxw!/office.dtd" not found.
- }}}
- 
- This is correct, the dtd is not in the zipped file.  It's only a reference.
- 
- !4. Fixing problem 1: modify the catalog
- I modified the /resources/entities/catalog file.  I added two lines
- \\(Thanks Upayavira for showing me this thing)
- 
- {{{
- -- Open Office DTDs --
- PUBLIC "-//OpenOffice.org//DTD OfficeDocument 1.0//EN" "office.dtd"
- PUBLIC "-//OpenOffice.org//DTD Manifest 1.0//EN" "Manifest.dtd"
- }}}
- 
- That corrects the error, but gives a new one ....
- 
- {{{
- org.apache.cocoon.ProcessingException: Failed to execute pipeline.: org.xml.sax.SAXParseException:
- A '(' character or an element type is required in the declaration of element type "draw:text-box".
- }}}
- 
- !5. Fixing problem 2: modify the DTD
- Appearantly, there's something in that file.  I looked at it, but I could not
- find a mistake.  I'm not an expert on those things, so, maybe someone can
- look into it for me ....
- 
- I used a workaround however.  You can modify the
- /resources/entities/office.dtd (from OO) file.  There's entries like this:
- 
- 
- {{{
- <!ENTITY % dtypes-mod SYSTEM "dtypes.mod">
- %dtypes-mod;
- <!ENTITY % nmspace-mod SYSTEM "nmspace.mod">
- %nmspace-mod;
- <!ENTITY % office-mod SYSTEM "office.mod">
- %office-mod;
- <!ENTITY % style-mod SYSTEM "style.mod">
- %style-mod;
- <!ENTITY % meta-mod SYSTEM "meta.mod">
- %meta-mod;
- <!ENTITY % script-mod SYSTEM "script.mod">
- %script-mod;
- <!ENTITY % drawing-mod SYSTEM "drawing.mod">
- %drawing-mod;
- <!ENTITY % text-mod SYSTEM "text.mod">
- %text-mod;
- <!ENTITY % table-mod SYSTEM "table.mod">
- %table-mod;
- <!ENTITY % chart-mod SYSTEM "chart.mod">
- %chart-mod;
- <!ENTITY % datastyl-mod SYSTEM "datastyl.mod">
- %datastyl-mod;
- <!ENTITY % form-mod SYSTEM "form.mod">
- %form-mod;
- <!ENTITY % settings-mod SYSTEM "settings.mod">
- %settings-mod;
- }}}
- 
- When you remove them all, the generator should work
- (Sax does not check a lot, this is a workaround, not a solution ;-) )
- 
- !6. Aggregation
- Next thing I did, was to use the <map:aggregate> to combine the files from the
- zipped file into one.  I enclose the original xml from all the files in a new
- <document> tag.  At first, I used the <office:document> tag, but this gave problems
in my XSL.
- 
- After that, it outputs both files as a combined xml file, like we needed ! 
- 
- !7. Sample XSL
- I then reused an xsl file I wrote before, when I extracted the files to xml
- with a little perl too.  This xsl file generates a very simple page in html,
- based on the document ...

- Et voila !!!!  That's it ....
- \\Once again, thanks to all who helped.
- 
- Could somebody please check this to see if he/she could reproduce my work on
- his/her machine ??
