Using a dynamic URL to add a picture with XSL:FO

Question

Hi there,

I want to add an image to my PDF output. The problem ist, that

<fo:external-graphic src="url('URL here')"/>

will accept nothing but an URL. The link to the image I want to add however is derived from another value inside the XML document being transformed.

Is there any way to generate image URL dynamiclly?

Thanks in advance sebastian

Answer 1

Use Attribute Value Template

An attribute value template consists of an alternating sequence of fixed parts and variable parts. A variable part consists of an XPath expression enclosed in curly brackets ({}). A fixed part may contain any characters, except that a left curly bracket must be written as {{ and a right curly bracket must be written as }}.
