Hi, I'd like to write a Lua function that processes the href attribute from a HTML file and outputs different content depending on the URL. However, I don't know how to convert the XML attribute and the contents of the link tag to a string value for the Lua function. I've tried the following, which does not work but makes my intention clearer: \startxmlsetups xml:a \directlua{getlinkcode("\\xmlatt{#1}{href}", "\\xmlflush{#1}")} \stopxmlsetups It's probably calls to lxml.att and lxml.flush instead of the strings, but how do I convert the "#1" ?
