我想从XML文档中显示VehicleLicensePlateState代码，具体取决于是否是加拿大州代码（例如AB，BC等）或美国州代码（WI，IL等）。
首先，我需要检查XML文档中是否找到加拿大或美国的VehicleLicensePlateState代码。
如果两者都找不到，我想显示JurisdictionText（在XML文档中路径为/ Integration / Citation / Agency / @Word）
我的IXML文档一次只能有一个VehicleLicensePlateState代码，而不是美国或加拿大，但不能同时拥有两个。
为了检查Canadian VehicleLicensePlateState代码，有一个查找.xsd文档。
还有一个带有US VehicleLicensePlateState代码的.xsd文档。我已经为每个发布了缩写代码。
根据我当前的XML文档，输出应该如下所示
<nc:IdentificationJurisdiction>
<nc:JurisdictionUSPostalServiceCode>QC</nc:JurisdictionUSPostalServiceCode>
</nc:IdentificationJurisdiction>
