This tip shows how to insert an image into the result-tree of an XSLT transformation using the
unparsed-entity-uri function.
Suppose you have this element:
<sigla SF="SiglaFirma"/>
And an unparsed entity such as a bitmap:
<!ENTITY SiglaFirma SYSTEM "sigla.bmp" NDATA bmp>
You can "load"
sigla.bmp into a XSLT result tree like this:
<img src="{unparsed-entity-uri('SiglaFirma')}" />
