Hello,

in several docbook XML files, i have:

<mediaobject>
<imageobject>
<imagedata fileref="../images/pic1.png"/>
</imageobject>
</mediaobject>

because my XSL toolchain is complicated, fop doesn't manage to find the
png files (bad location). So i would like to preprocess the files by
changing the URLs from "../images/" to "docbook/data/images/". The rest
of the file must not change. Is it possible/easy to do in XSL? If yes, how?

Thanks

Start with the standard "identity transformation" stylesheet. That will
copy the document unchanged.

Then add a template which recognizes the once case you want to handle
differently, and which implements that difference. For example
(untested, and may be slight overkill):

<xsl:template match="imagedata/@fileref[substring(.,0,3)='../']">
<xsl:attribute name="fileref"
select="concat('docbook/data',substring(.,3))"/>
</xsl:template>
