Hi,
The ids get generated on the fly during the XML to FO transformation, for the
original <text> tags, and get output in the FO format as <fo:block id=…> . This
is expressed as
<fo:block id="#{generate-id()}"
in the XSL document. See generate-id() in
http://www.w3schools.com/XSL/func_generateid.asp . So basically, I’m just doing
the XSLT transformation (my own format to FO), and adding as bonus the id
generation. Find the XSLT and FO details below
Cheers
Igor
------
The relevant parts of the XSL look like
<xsl:template match="body">
<fo:block space-after.optimum="3pt" space-before.optimum="4pt">
<xsl:apply-templates/>
</fo:block>
</xsl:template>
<xsl:template match="text">
<xsl:if test="@alignment='Left'">
<fo:block id="#{generate-id()}"
font-size="8pt" font-weight="normal" font-family="sans-serif" line-height="9pt"
space-after.optimum="8pt" text-align="left">
<xsl:value-of select="."/>
</fo:block>
</xsl:when>
------
A section of the output fo, as produced by apache fo, looks like this (indented
by me) – see how the ids appear in the fo:block tags
<fo:block>
<fo:block text-align="right" space-after.optimum="8pt" line-height="9pt"
font-family="sans-serif" font-weight="normal" font-size="8pt" id="#N10011">
Adress 1 line
</fo:block>
<fo:block text-align="right"space-after.optimum="8pt" line-height="9pt"
font-family="sans-serif" font-weight="normal" font-size="8pt" id="#N10017">
Address 2 line
</fo:block>
<fo:block text-align="center" space-after.optimum="10pt" line-height="13pt"
font-family="sans-serif" font-weight="normal" font-size="12pt" id="#N1001F">
Another text line in different font
</fo:block>
</fo:block>

Subject: Re: Absolute position of original text in final PDF
Hi Igor,
It is not clear to me how these <text> elements are defined - in your xml
input? If so how do you transform them to fo whilst retaining the id
attribute? Could you provide a small example of the xml and the corresponding
xsl that you wish to be input of fop.
Thanks,
Pete

Dear FOP mailinglist readers,
I’ve been fighting with the Apache FOP source for a week, but I can’t solve my
problem alone…
One of the features of the application I’m writing produces a PDF, based on an
XML that follows a simple schema (header info, tables, images and text, but
nothing fancy). Generating the FO then the PDF are the easy steps. Fop does the
job marvelously. Now I need to output to the user the coordinates of bounding
boxes. Those bounding boxes must represent the placement in the PDF of the
original text within the XML. To provide an example:
If I had in my original XML ,
<text id=”xxx”>This text appears somewhere in the PDF</text>
I would want, during the XML to PDF process, to output something like
Bounding_box {id=”xxx”, x=34, y=45, w=444,h=25}
I understand this as “the original text of tag xxx is contained in the pdf in
the rectangle starting at point (34,45), of width 444, and height 25”
(if the text is split into several pages or areas, receiving a list of
rectangles would be fine)
To summarize: how can I know the position in the final PDF of the original text?
I’ve tried decorating different classes of FOP, looking at the FOTreeBuilder,
the AreaTreeParser, but failed to maintain the identifier of the original text
tags.
I’d prefer staying with release 0.95, but can also use the trunk if required.
While browsing, I thought that the accessibility features might help, but
couldn’t figure out how
http://svn.apache.org/viewvc/xmlgraphics/fop/trunk/src/documentation/content/xdocs/trunk/accessibility.xml?view=markup
I thought relying on the Area Tree, but couldn’t retrieve the original id that
were set to the original XML tags.

Thanks for any help
