2 XML and XSL Questions

I have two questions that I have been trying to find an answer to for months now. The first is displaying pictures that are in the filemaker container fields. The latest thing I have done is make a seperate field and call it pictureurl and have it in the xsl stylesheet by:

<xsl:value-of select="pictureurl" disable-output-escaping="yes"

so it works as long as I enter in the xml location of the picture manually. I need it to automatically calculate the pitureurl once I insert the picture into the caluculation field though. Is the way to do this by using the external function web-to-html or something of that nature?

My second question is about text wrapping in a field. I have a long field which is sort of the body of a document that I need in the XSL. So far when it displays on the browser as a long line that goes all the way across and I have to scroll over to see it all. I am needing it to wrap to the next line after lets say if the length of the body is > 300. I have tried many fmp calculation scripts to do this and nothing works on the xsl. I have also tried many examples that people have given me with the xsl. Is there any correct way to do this?

Thanks.
