retrive a parameter in the xsl
Hi,
i want to obtain the pagination under this form: Page 1 of 12
there is an interesting link in the Apache Fop FAQ http://xmlgraphics.apache.org/fop/fo.html#fo-total-pages
but i'm having trouble to get the wanted result , in my pdf rendering class
i do the tranformation 2 times , the first time i check if there is any problem with the xsl or the xml data then i got and generate the pdf wich is the final rendering so in the first one i retrieve the number of pages and i use the result in the second rendering.
//setup XSLT
TransformerFactory tranFactory = TransformerFactory.newInstance();
Transformer aTransformer = tranFactory.newTransformer(xsltfile);
aTransformer.setParameter("page-count",nbrPages);
aTransformer.transform(src, res);
System.out.println("getParameter : "+aTransformer.getParameter("page-count"));
it works the print print the number of pages now in my xslt
i declare a variable like:
<xsl:variable name="page-count"></xsl:variable>
and i'm trying to print it:
<xsl:value-of select="$page-count" />
but no result(i'm feeling like missing something btu what ;d?) ?
and thanks a lot

RE: retrive a parameter in the xsl
Posted by Eric Douglas <ed...@blockhouse.com>.
Rather than trying to transform it twice so the second time knows the
number of pages, I found the simplest way to get the page count is to
force a page reference onto the last page.
...
</xsl:for-each>
</xsl:for-each>
<fo:block>
<xsl:attribute name="id">last-page</xsl:attribute>
<xsl:attribute
name="position">absolute</xsl:attribute>
<xsl:attribute name="left">0</xsl:attribute>
<xsl:attribute name="top">0</xsl:attribute>
<xsl:attribute name="width">0</xsl:attribute>
<xsl:attribute name="height">0</xsl:attribute>
</fo:block>
</fo:flow>
...
Then where I want to put the last page number into my text, I put a page
number variable I made up into my text tag in the xml:
<xsl:for-each select="TEXT">
<xsl:choose>
<xsl:when test="VARIABLE =
'%CURRENT_PAGE%'"><fo:page-number /></xsl:when>
<xsl:when test="VARIABLE =
'%LAST_PAGE%'"><fo:page-number-citation ref-id="last-page"/></xsl:when>
<xsl:otherwise><xsl:value-of
select="."/></xsl:otherwise>
</xsl:choose>
</xsl:for-each>

Hi,
what you need is xsl:param instead of xsl:variable. the syntax is the
same for both elements.
Note that this list is for FOP usage; to ask XSLT questions, the list
cited in [1] is more relevant.
