<div dir="ltr"><div><div><div><br></div>Hi<br><br>The returned xml from this query is invalid according to the fdsn stationxml spec. :<br><br><a href="http://service.iris.edu/fdsnws/station/1/query?network=IU&station=ANMO&loc=00&channel=BHZ&level=response&nodata=404">service.iris.edu/fdsnws/station/1/query?network=IU&station=ANMO&loc=00&channel=BHZ&level=response&nodata=404</a><br>
<br></div>The xschema requires all <Zero> elements to come before all <Pole> elements in a <PolesZeros> element, but the document has <Pole>s and then <Zero>s. <br><br>This is a case where xschema's lack of ability to allow unordered content makes it hard to use. RelaxNG has a much nicer way of specifying a schema IMHO, but I guess that stationxml is unlikely to change from xschema.<br>
