如何从URI获取xml命名空间的前缀?
示例:
<Name xmlns:tiger="http://www.census.gov">
</Name>
我有
"http://www.census.gov"
我想获得前缀
tiger
如何在Actionscript / Flex中执行此操作?

答案不适用于这个复杂的例子:
<Name xmlns:tiger="http://www.census.gov" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.opengis.net/wfs" xmlns:wfs="http://www.opengis.net/wfs" xmlns:ows="http://www.opengis.net/ows" xmlns:gml="http://www.opengis.net/gml" xmlns:ogc="http://www.opengis.net/ogc" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:it.geosolutions="http://www.geo-solutions.it" xmlns:cite="http://www.opengeospatial.net/cite" xmlns:worldWS="worldWS" xmlns:sde="http://geoserver.sf.net" xmlns:topp="http://www.openplans.org/topp" xmlns:sf="http://www.openplans.org/spearfish" xmlns:nurc="http://www.nurc.nato.int" xmlns:solWS="solWS">
tiger:poly_landmarks
</Name>
我有空数组。
我自己的答案
对于编辑示例
var xml:XML = <Name xmlns:tiger="http://www.census.gov" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.opengis.net/wfs" xmlns:wfs="http://www.opengis.net/wfs" xmlns:ows="http://www.opengis.net/ows" xmlns:gml="http://www.opengis.net/gml" xmlns:ogc="http://www.opengis.net/ogc" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:it.geosolutions="http://www.geo-solutions.it" xmlns:cite="http://www.opengeospatial.net/cite" xmlns:worldWS="worldWS" xmlns:sde="http://geoserver.sf.net" xmlns:topp="http://www.openplans.org/topp" xmlns:sf="http://www.openplans.org/spearfish" xmlns:nurc="http://www.nurc.nato.int" xmlns:solWS="solWS">
tiger:poly_landmarks
</Name>
var ns:Namespace = xml.namespace("http://www.census.gov");
if(ns.uri == "http://www.census.gov")
....
答案 0 :(得分:2)
var xml:XML = <Name xmlns:tiger="http://www.census.gov"></Name>;
var ns:Array = xml.namespaceDeclarations();
trace(ns[0].prefix); //output: tiger
复杂xml的UPD(输出tiger
):
var xml:XML = <Name xmlns:tiger="http://www.census.gov" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.opengis.net/wfs" xmlns:wfs="http://www.opengis.net/wfs" xmlns:ows="http://www.opengis.net/ows" xmlns:gml="http://www.opengis.net/gml" xmlns:ogc="http://www.opengis.net/ogc" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:it.geosolutions="http://www.geo-solutions.it" xmlns:cite="http://www.opengeospatial.net/cite" xmlns:worldWS="worldWS" xmlns:sde="http://geoserver.sf.net" xmlns:topp="http://www.openplans.org/topp" xmlns:sf="http://www.openplans.org/spearfish" xmlns:nurc="http://www.nurc.nato.int" xmlns:solWS="solWS">
tiger:poly_landmarks
</Name>
var nss:Array = xml.namespaceDeclarations();
for each(var ns:Namespace in nss)
{
if(ns.uri == "http://www.census.gov")
{
trace(ns.prefix);
break;
}
}
