Error when creating multiple files
I'm trying to create different files from the names listed in an xml file. I've used key grouping in order to ensure that I don't repeat names which appear various times. However, when I execute the processor I get an error that seems to say that i'm trying to create the same file twice.
Here's the complete error :
Code:
Error at xsl:result-document on line 100 of generate-author-pages.xsl:

As you use XSLT 2.0 I would simply use xsl: for-each-group to eliminate duplicate authors instead of working with keys.
That might simplify the code.
It also appears the code extracting parts of the name could be simplified making use of the XSLT 2.0 xsl: analyze-string instruction or the XPath 2.0 tokenize function.
As for the error with the attempt to write the same file twice with one transformation, I am not able to identify the reason for that by reading your code snippets. If you need help debugging that then consider to post minimal but complete samples allowing us to reproduce the problem.

Well, I made minor changes according to your comments. Here's my new xsl file :

I didn't use analyze-string yet because i'm having trouble detecting the last word of the name. I tried using the regex [a-zA-Z\-]+$, \s[a-zA-Z\-]+$ and even .+$ but apparently it never detects anything. Any help for this?
If you want to try out for my main error, here's a link to my xml file : http://dl.dropbox.com/u/13990374/dblp-excerpt.xml

There is one author "BaoCang Ding" and one "Baocang Ding" and I think your code for grouping distinguishes them as unique respectively different names while later on when you create files names your code does some normalization to lower case letters (and/or the file system on the OS does not distinguish between lower and upper case letters in files names), so that seems to be one reason why the XSLT processor gives that error that the stylesheet tries to write twice to a file with a certain name "D/Ding.baocang.html".
So in your grouping code you need to make sure you group on the normalized names.

Totally worked, thanks! :D And do you have any idea for the regex? What I have already works but it would be better if I can simplify the code for readability. This is the xsl I use for testing it :
Code:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:variable name="capitals" select="'AZERTYUIOPQSDFGHJKLMWXCVBN'"/>
<xsl:variable name="smalls" select="'azertyuiopqsdfghjklmwxcvbn'"/>
<xsl:template match="/">
<xsl:apply-templates select="//author[.='José E. Gallardo']"/>
</xsl:template>
<xsl:template match="author">
<xsl:call-template name="create-filename">
<xsl:with-param name="name" select="translate(.,$capitals,$smalls)"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="create-filename">
<xsl:param name="name"/>
<xsl:analyze-string select="$name" regex=".+$">
<xsl:matching-substring>
<xsl:variable name="letter" select="substring(regex-group(1),1,1)"/>
<xsl:variable name="lastname" select="normalize-space(translate(regex-group(1),'.-','=='))"/>
<xsl:variable name="firstname" select="translate(normalize-space(substring($name,1,string-length($name)-string-length($lastname))),' .-','===')"/>
<xsl:variable name="temp-filename" select="concat($letter,'\',$lastname)"/>
<xsl:variable name="temp2-filename" select="concat($temp-filename,'.',$firstname)"/>
<xsl:variable name="filename" select="concat($temp2-filename,'.html','')"/>
<xsl:result-document href="{$filename}">
<xsl:value-of select="."/>
</xsl:result-document>
</xsl:matching-substring>
</xsl:analyze-string>
</xsl:template>
</xsl:stylesheet>
And here's a sample xml to test it with :
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dblp SYSTEM "dblp.dtd">
<dblp>
<incollection mdate="2007-09-21" key="books/ws/BMW07-papers/GallardoCF07">
