Is the result of this builder reusable? XQueryBuilder.xquery("//foo");

I want to perform an XQuery outside of DSL (in a Processor).  Something like:

 XQueryBuilder hostXQ = XQueryBuilder
    .xquery("//remote[remoteId/@value='CBOE34']/server/@value");
 String host = hostXQ.evaluateAsString(exchange);

Second question is can I parameterize the XQuery like so:

 XQueryBuilder hostXQ = XQueryBuilder
    .xquery("//remote[remoteId/@value=$accountId]/server/@value");

        hostXQ.setParameters(new HashMap<String, Object>() {{
                put("accountId", "CBOE34");}});
        String host1 = hostXQ.evaluateAsString(exchange);

        hostXQ.setParameters(new HashMap<String, Object>() {{
            put("accountId", "CBOE78");}});
        String host2 = hostXQ.evaluateAsString(exchange);


Thanks,


Chris

I think you can use the XQueryBuilder in the Processor just like you showed.
If you want to call the evaluateAsString multiple times, you need to make sure the message body is reread able.  
You can convert the message body into String before you process it in your processor.
