调用WebService返回xml数据集出这样的错误!

好久没来这了! 下面是客户反回来的错误信息:
哪位大哥知道,指教下!!!
谢谢了!

抛出异常的接口是：读取故障单的处理结果的时候，接口参数：

对象是alg；读取信息是："id", "z_wf_task", "z_wf_route", "analyst","z_begin_dt","z_complete_dt", "description"

AMS接口中捕获的异常是：System.InvalidOperationException: XML 文档(1, 687)中有错误。 ---> System.Xml.XmlException: “”(十六进制值 0x08)是无效的字符。行 52，位置 55。

查看最近的接口日志发现：CMCP系统调用了AMS系统的Web Service接口查询时，接口里返回异常信息如下：

at System.Xml.XmlScanner.ScanHexEntity()

at System.Xml.XmlTextReader.ParseBeginTagExpandCharEntities()

at System.Xml.XmlTextReader.Read()

at System.Xml.XmlLoader.LoadCurrentNode()

at System.Xml.XmlLoader.ReadCurrentNode(XmlDocument doc, XmlReader reader)

我在网上乱找,不知道有可能是下面几个原因不.

1、WebService 返回复杂类型的数据结构，.Net 和 Java 不能正常调用的问题。
2、XML格式不同导致(WebService封装的与当前支持的xml)
3、Xml Serialization BUG, 调用Web Service容易出错
