Xml Web服务响应的xslt表中出错

伙计们，我需要为来自webservice的响应提交设计xsl表，但我面临的问题是，来自webservice的每个xml标记的格式都是“ns1:element name”，但在样式表中使用它时，会显示错误“前缀ns1未定义”

xslt语句如下所示：

 <xsl:template match="ns1:OTA_AirLowFareSearchRS">

    <xsl:for-each select ="ns1:OTA_AirLowFareSearchRS/PricedItineraries/PricedItinerary">

<ns1:OTA_AirLowFareSearchRS Version="2.001" xmlns="http://www.opentravel.org/OTA/2003/05" xmlns:ns1="http://www.opentravel.org/OTA/2003/05">

       <ns1:PricedItineraries>
        <ns1:PricedItinerary CompositeFlightNumber="AI" CountCompositeFlightNumber="1" FareType="Non-Refundable" InboundSegmentReference="1" MatrixFare="true" Mode="" OriginDestinationRPH="BLRHYDAI517AI20130321" OutboundSegmentReference="1" Priority="1" RecommendationRPH="1" Refundable="true" ReturnOnly="false" SequenceNumber="1.0" SupplierCode="1AWS">

来自webservice的示例xml如下所示：

3032

将名称空间添加到xslt中

<xsl:stylesheet xmlns:ns1="http://www.opentravel.org/OTA/2003/05">

添加后，可以在XSLT中使用名称空间

<xsl:template match="ns1:OTA_AirLowFareSearchRS">
