我在Tibco business works模块中有以下代码
$ES_GetInfo/root/pfx4:GetInformationAndPropertyDetailsResponse/pfx4:LicenseInfo/pfx4:CoreEnt/pfx4:Ent
[pfx4:Ent/pfx4:EntOfferingCode = $Read_DB_Data/group/ROW/EOC]
/pfx4:EntState = "Disabled"我可以理解它是在将"EntOfferingCode"与"EOC"进行比较,但无法获得表达式"/pfx4:EntState = 'Disabled'"
根据TIBCO,整个表达式返回一个布尔值。
"/pfx4:entState='Disabled'"是什么意思?是合乎逻辑的,还是有条件的,还是其他的?

整个表达式都是逻辑条件。“/”只是XPath (XML Path Language)语法中的xml schema元素分隔符。您可以从这里的https://docs.tibco.com/pub/activematrix_businessworks/6.3.0/doc/html/GUID-D319018B-AA74-428D-A034-E477778AD2B6.html开始学习tibco xpath
该表达式首先过滤所有EntOfferingCode = $Read_DB_Data/group/ROW/EOC的"Ent“节点,然后检查过滤结果中是否存在EntState =”Disabled
该表达式可以替换为
not (empty($Start/pfx:GetInformationAndPropertyDetailsResponse/pfx:LicenseInfo/pfx:CoreEnt/pfx:Ent[ pfx:EntOfferingCode= "EOC" and pfx:EntState = "Disabled"]))例如
如果模式类似于

$ES_GetInfo/root/pfx4:GetInformationAndPropertyDetailsResponse/pfx4:LicenseInfo/pfx4:CoreEnt/pfx4:Ent/pfx4:EntState = "Disabled"它将为这两个示例返回true
