大家都知道,soap是使用XML进行类型编码的,D6 Webservice支持olevariant类型直接调用,那,是怎样把olevariant转成xml包的呢?
我想把多个Clientdataset.data(olevariant类型)转成一个xml包,再在后端又把xml包拆分成多个olevariant,应该怎样做呢?
如:Clientdataset.data-->olevariant经转换后成如下格式:
<state xsi:type="xsd:base64Binary">
lhngvQEAAAAYAAAADAAbAAAAAwAAAFYBBmJvbV9ubwEASQAAAAEABVdJRFRIBAABABIAAAAHd
mVyc2lvbgEASQAAAAEABVdJRFRIBAABAAMAAAALRGVzY3JpcHRpb24BAEkAAAABAAVXSURUSAQAA
....
</state>
那位知道如何转换,我好急啊,在线等待!
