Re: xsl can't get graphic to load from xml file
Ok, I don't think that I mentioned that I am new to this xml and xsl thing. So basically what you are saying is that I cannot have a dynaminc path (one read in from the xsl sheet) and place it in the url? My absolute path is already in the xml. There is no generation what-so-ever. So can this xml data be read into local xsl:variable and then used in the url? I am using apache.xml.fop to generate my pdf off of my xsl. --- Eliot Kimber <ekimber@xxxxxxxxxxxxxxxxxxx> wrote: > There is no simple single solution to this problem > because it depends > entirely on the relative locations of the FO > instance (if you are > generating an instance) and the graphic *at the time > you render them*, > not at the time you generate the FO. > > Therefore, for different processing environments, it > might be most > appropriate to generate an absolute path and in > others you have to > generate a relative path relative to some > pre-defined location. > > In addition, doing path processing is generally > easier in a language > like Java than in XSLT (although you can do it in > XSLT, of course).
