Hans, I have the following sample: \startbuffer[demo] <doc> <div id="a-b"> is it working </div> </doc> \stopbuffer \startxmlsetups xml:initialize \xmlsetsetup{#1}{doc}{xml:*} \xmlsetsetup{#1} {div[@id='a\letterpercent-b']} {xml:a:b} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:a:b \input knuth \stopxmlsetups \starttext \xmlprocessbuffer{main}{demo}{} \stoptext The only way to get the Knuth in the quote is to remove "\letterpercent" in the lpath. I guess I must be doing something wrong in this sample. In my real document, I cannot simply remove it, I get an error. As a general consideration, houw about making not mandatory to escape characters in lpaths? This would ease the traslation from XML code to lpaths. Many thanks for your help, Pablo -- http://www.ousia.tk
