> I like to use a split step with the XPathBuilder in a routetemplate.
> It's possible to create a template with a split like this:
> routeTemplate("split-xpath-router")
> .templateOptionalParameter("expression")
> .templateParameter("in")
> .templateParameter("out")
> .from("\{{in}}")
> .split().xpath("\{{expression}}")
> .to("\{{out}}")
> .end()
> However, it doesn't seem possible to use XPathBuilder in the template,
> because the template parameter doesn't get interpolated. This leads to:
> javax.xml.xpath.XPathExpressionException: net.sf.saxon.trans.XPathException:
> Unexpected token "{" at start of expression
> I tried with:
> routeTemplate("split-xpath-router")
> .templateOptionalParameter("expression")
> .templateParameter("in")
> .templateParameter("out")
> .from("\{{in}}")
> .split().xpath("\{{expression}}")
> .to("\{{out}}")
> .end()
> I tried it like this:
> .split({color:#cc7832}new
> {color}XPathBuilder({color:#6a8759}""{color}).saxon().threadSafety({color:#cc7832}true{color}))
> And
> .split().method({color:#cc7832}new
> {color}XPathBuilder({color:#6a8759}""{color}))
> I expected it something like this:
> routeTemplate("split-xpath-router")
> .templateOptionalParameter("expression")
> .templateParameter("in")
> .templateParameter("out")
> .from("\{{in}}")
>
> .split().xpathBuilder("\{{expression}}").saxon().threadSafety({color:#cc7832}"true"{color})
> .to("\{{out}}")
> .end()
