Compute節(jié)點的ESQL是：
CREATE COMPUTE MODULE flow_Compute
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
-- XML操作示例
SET OutputRoot.XML.employee.(XML.Attribute)id = '001';
SET OutputRoot.XML.employee.name = 'Felix';
SET OutputRoot.XML.employee.age = 33;
SET OutputRoot.XML.employee.address[1] = 'Dalian 88';
SET OutputRoot.XML.employee.address[2] = 'Beijing 188';
SET OutputRoot.XML.employee.address[3] = 'Shanghai 288';
SET OutputRoot.XML.employee.title.VALUE = NULL;
SET OutputRoot.XML.employee.salary VALUE = NULL;
SET OutputRoot.XML.employee.Comments.(XML.Content)=NULL;
RETURN TRUE;
END;
END MODULE;
最終得到的XML是：
<employee id="001"><name>Felix</name><age>33</age><address>Dalian 88</address><address>Beijing 188</address><address>Shanghai 288</address><title/><salary></salary><Comments/></employee>
