我正在使用php soap,我已经请求xml:
<?xml version="1.0" encoding="utf-16"?>
<Search xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<ExtraParamList i:nil="true" />
<Form>
<ProductId>20</Id>
</Form>
</Search>
我有错误:The prefix 'i' is not defined.
如果删除i:nil="true"
我有错误Object reference not set to an instance of an object.
