Getting values within anchor tag in process variables in Process Model

Hi All,

In Script Task, I am calling a rule, and storing its result in a process variable, which further needs to be passed in Execute Stored Procedure Plug-in. The plug-in is sending alert notification that Missing required ACP with name: P_VALUE_NAMES, but I have passed the value to the ACP. On monitoring the process variable, the string is getting stored in the following format and not in normal text (Appian version 17.4)

<a title="Filing_Type;Rep_Period_Type;Rep_Period_Year;Rep_Period_Start_Dt;Rep_Period_End_Dt;Rep_Content_Type;Reporting_Code;Freq_Change_Code;Qtr_Of_Change;Content_Change_Code;Last_Rep_Flag;No_Rep_Flag;Sys_Calc_Res_Set;Generate_Report_Flag;Initiate_Req_Flg;Reporting_Period_Close;Aifm_File_Name;Fund_Status_Flg;Xml_Version">Filing_Type;Rep_Period_Type;Rep_Period_Year;Rep_Period_Start_Dt;Rep_Period_End_Dt;Rep_Content_Type;Reporting_Code;Freq_Change_Code;Qtr_Of_Change;Content_Change_Code;Last_Rep_Flag;No_Rep_Flag;Sys_Calc_...</a>

Please advise on how to remove the anchor tag and to get the value in the process variable as 

"INIT|H1|2014|01/04/2014|30/06/2014|1|3|null|null|null|FALSE|TRUE|YES|YES|null|SDG848_DATMAN_AMF_000001_14|OPEN|1.2~AMND|Q1|2017|01/01/2017|31/03/2017|2|4|null|null|null|FALSE|FALSE|YES|YES|null|FISL3_|OPEN|1.1"

Thanks and Regards
