caml - Caml Query：如何添加附加参数？

Question

我有一个工作查询，我想在查询中添加其他参数，例如：

<Or>
<Eq><FieldRef Name="Service_x0020_Line" /><Value Type="Choice">RPCS</Value></Eq>
<Eq><FieldRef Name="Service_x0020_Line" /><Value Type="Choice">PLM</Value></Eq>
</Or>

我怎么能在这里添加它？：

<And>
<Or>
<Or>
    <Eq><FieldRef Name='BM_x0020_Status' /><Value Type='Choice'>Completed</Value></Eq>
    <Eq><FieldRef Name='BM_x0020_Status' /><Value Type='Choice'>Not yet submitted</Value></Eq>
</Or>
    <Eq><FieldRef Name='BM_x0020_Status' /><Value Type='Choice'>For Approval</Value</Eq>
    </Or>
    <Eq><FieldRef Name='Approval_x0020_Month' /><Value Type='Text'>"+approvalmonth+"</Value></Eq>
    </And>
