Approval Setting时特殊字符的问题：

如果Approver_Role输入了“
”，那么在申请表单时什么出错，因为在组合XML字符串时遇到了

ServiceForFlowER.cs

approvalXML += "<Approver>"

                            + "<Approver_ID>" + GetEmpID(approverTable.Rows[i][entityApprover.Approver.PhysicalFieldName].ToString()) + "</Approver_ID>"

                            + "<Sequence_No>" + approverTable.Rows[i][entityApprover.ApprovalOrder.PhysicalFieldName].ToString() + "</Sequence_No>"

                            + "<Approver_Role>" + approverTable.Rows[i][entityApprover.Role.PhysicalFieldName].ToString() + "</Approver_Role>"

                            + "</Approver>";

PS：

不合法的XML字符必须被替换为相应的实体。

如果在XML文档中使用类似"

<message>if salary < 1000 then</message>

为了避免出现这种情况，必须将字符"

<message>if salary < 1000 then</message>

下面是五个在XML文档中预定义好的实体:

0c32ad7c6bd6ed742d8142007026ab10	>	大于号
&	&	和
'	'	单引号
"	"	双引号

实体必须以符号"&"开头，以符号";"结尾。

注意: 只有"
