How to convert HTML tags(rich text) into XML-FO?
I have a basic task. The website has a text area to type some comments.
Currently it's a regular text area and the text is appearing as is in
generated PDF using FOP-0.95.
Now new task is to enable user to create rich text for the comments. I will
probably use Yahoo UI JavaScript library. Or do you have other suggestions?
As a result, Yahoo JS will generate some HTML tags in this text. So how to
convert those tags into PDF with FOP (how to interpret those tags)?
Thank you,
-Gennady

Hi Ferran,
Thank you for your suggestion.
Actually, this is what I ended up doing in FOP jsp file:
//handle bold
formatNotes = formatNotes.replaceAll("<strong>", "<fo:wrapper
font-weight=\"bold\">");
formatNotes = formatNotes.replaceAll("</strong>", "</fo:wrapper>");
//handle italic
formatNotes = formatNotes.replaceAll("<em>", "<fo:wrapper
font-style=\"italic\">");
formatNotes = formatNotes.replaceAll("</em>", "</fo:wrapper>");
//handle color
formatNotes = formatNotes.replaceAll("", "</fo:wrapper>");
//handle font-size
formatNotes = formatNotes.replaceAll("", "<fo:wrapper
text-decoration=\"underline\">");
formatNotes = formatNotes.replaceAll("</u>", "</fo:wrapper>");
formatNotes = formatNotes.replaceAll("<p>", "");
formatNotes = formatNotes.replaceAll("</p>", "");
And then finally, this:<fo:block font-size="12pt" text-align="left"
font-family="sans-serif" color="black">
<fo:wrapper font-weight="bold">My
Remarks:</fo:wrapper>
<%= formatNotes %>
</fo:block>
I know, it's a stupid way, but it works out well - doesn't create me any
extra stuff.

Hello,
I have developed a simple example using namespaces:
The XML:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<name>TEST HTML-FO</name>
<descripcion xmlns="http://www.w3.org/1999/xhtml">Pellentesque habitant
morbi tristiquesenectus et netus et malesuada fames ac
<u>turpis</u></descripcion>
</root>
the XSLT:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:xhtml="http://www.w3.org/1999/xhtml">
...
<fo:flow flow-name="xsl-region-body" font-size="10pt">
<fo:block font-size="15pt">
<xsl:value-of select="name"/>
</fo:block>
<fo:block font-size="15pt">
<xsl:apply-templates select="xhtml:descripcion"/>
</fo:block>
</fo:flow>
...
<!-- HTML ENTITIES -->
<xsl:template match="xhtml:b">
<fo:inline font-weight="bold">
<xsl:apply-templates/>
</fo:inline>
</xsl:template>
<xsl:template match="xhtml:i">
<fo:inline font-style="italic">
<xsl:apply-templates/>
</fo:inline>
</xsl:template>
<xsl:template match="xhtml:u">
<fo:inline text-decoration="underline">
<xsl:apply-templates/>
</fo:inline>
</xsl:template>
</xsl:stylesheet>
May be it usefull...
I attach the files.

If the content of the comment edit-box is posted back to the server,
it will (should) contain only the linefeeds explicitly entered by the
user. If that text is subsequently saved to a database and transformed
to FO for output, then specifying linefeed-treatment="preserve" on the
surrounding fo:block should suffice to keep the hard returns/paragraph
marks in tact.
HTH!

Dear Andreas,
I am working on same problem as a was described below (using FOP to
create pdf with some dynamical fields entered by users included field
Comment) but I need to save at least breaks in Comment entered by users
just to let them have all their paragraphs not glued together. What you
can recommend me to do besides to ask users enter each paragraphs as a
separate comment?
Thank you.
Tatiyana.

Strictly speaking, you wouldn't need to save it as an XHTML *file*. If
you have it in a memory buffer somewhere, then this should do fine
too, but... (see below)

How then do you discern bold text from regular text in the source? I
mean: if the comment is saved in the database as "just some comment",
how would the processor know that the word "comment" is to appear in
bold? Are RTF commands stored in the database somehow?
Just a reminder: FOP converts FO to PDF (or other output formats).
That's it.
For convenience, the user can also supply XML with a stylesheet that
transforms the XML to FO before FOP actually processes it. If you need
to render something else than XML to PDF, FOP is actually not suited
for that task.

I can't really judge that based upon the info provided so far. It
depends greatly on the answer to my above question....

Hi Andreas,
Basically I am saving in the database some record from user input in Struts
Web app which has some 20 values like name, addreess, phone, email, ... and
1 value "coments" which is saved like this:
just some comment. So I don't want to save this value comments as a separate
XHTML file. For this I used Rich Text Editor I found here:
http://www.dynamicdrive.com/dynamicindex16/richtexteditor/index.htm
All I need is to send it along with name, address, etc. to FOP in order to
generate in PDF this - make word "comment" bolded:
just some comment
So what is the best way/tool/library to use to accomplish this?
Thanks so much for help.

Provided that the generated HTML is well-formed XHTML (= XML), it can
be transformed via XSLT to FO. There are various tools/stylesheets
available for that purpose, mentioned on FOP's resource page ( http://xmlgraphics.apache.org/fop/resources.html#products-other
)
