Hi Tiffany,

Could you post your XSLT sofar? And also some typical input XML, that'll
help too.

Cheers,

Subject: [xsl] Dynamic image and text alignment

i am trying to control the image and text alignment in my presentation
dynamically based on the user choice input.  the trick is to allow multiple
variations of image/text presentation on one page.

Page example:

paragraph 1 (user choice creates flag = left-right <xsl:if
test="body_image_placement='left-right'">)

	image flush left
	text right aligned to image


paragraph 2 (user choice creates flag = top-bottom <xsl:if
test="body_image_placement='top-bottom'">)

	image above text
	text below image

paragraph 3 (user choice creates flag = top-bottom <xsl:if
test="body_image_placement='top-bottom'">)

	no image
	text flush left

Rendered page:


paragraph 1		X	this is the text that appears
				right aligned to image



paragraph 2		X

			this is the text that appears below the
			image


paragraph 3		this is the text that apppears with no image


any suggestions?

No guarantees: but yes, that's what I would expect to happen.

I'm not clear what you mean.
