如何在Groovy Code SoapUI 中编写Xpath 查询？
How to write Xpath Query in Groovy Code SoapUI?
我是 groovy 脚本编写的新手，正在尝试编写应该使用此 Xpath 提供输出的代码：
/BillingInvoice/invoicedOrders/entry/value/lines/aggregationKey[text()='INV_GROUP_Meterreading' or text()='INV_GROUP_Power']/../(aggregationKey|amount)
此 Xpath 在在线 Xpath 格式检查中工作正常，但我无法在 Groovy 脚本中工作，因为我对它了解不多。
这里写一个Groovy脚本的目的是提取聚合键对应的所有金额并求和，但目前我连标签元素和值都卡住了
下面是我正在使用的XML，保存在SOAPUI 属性中。我在 Groovy 脚本中解析它：
<BillingInvoice>
<aggregation>
<aggregations>
<aggregations>
<key>INV_GROUP_Power</key>
<showUnitPrice>true</showUnitPrice>
<showVolume>true</showVolume>
<volumeUoM>kW</volumeUoM>
</aggregations>
<aggregations>
<key>INV_GROUP_Meterreading</key>
<showUnitPrice>true</showUnitPrice>
<showVolume>true</showVolume>
<volumeUoM>days</volumeUoM>
</aggregations>
<key>DISTRIBUTION</key>
<showUnitPrice>false</showUnitPrice>
<showVolume>false</showVolume>
</aggregations>

这是 groovy 脚本，它可以满足您的需求。
方法 #1 使用 XmlSlurper
即，使用可能的值之一搜索 aggregationKey 并找到相应 amount 的值并将它们相加。
//Define what key & possible values to filter
def filterMap = [aggregationKey:['INV_GROUP_Meterreading','INV_GROUP_Power']]
//Pass xmlString below, not added for saving space
def xml = new XmlSlurper().parseText(xmlString)
def result = filterMap.collect{ k,v -> xml.'**'.findAll{it.name() == k && it in v}*.parent()*.amount*.text()}.flatten().sum{it as Double}
log.info result
你可以快速在线试用这个demo
方法 #2 使用 xpath
请注意，用于检索所需金额和总和的正确 xpath 是 sum(//lines[aggregationKey[.='INV_GROUP_Meterreading' or .='INV_GROUP_Power']]/amount)
当然，如果有命名空间，那也需要处理。
脚本
import com.eviware.soapui.support.XmlHolder
//Pass xmlString, avoiding to save the space
def holder = new XmlHolder(xmlString)
def result = holder.getNodeValue("sum(//*:lines[aggregationKey[.='INV_GROUP_Meterreading' or .='INV_GROUP_Power']]/*:amount)") as Double
log.info result
我是 groovy 脚本编写的新手，正在尝试编写应该使用此 Xpath 提供输出的代码：
/BillingInvoice/invoicedOrders/entry/value/lines/aggregationKey[text()='INV_GROUP_Meterreading' or text()='INV_GROUP_Power']/../(aggregationKey|amount)
此 Xpath 在在线 Xpath 格式检查中工作正常，但我无法在 Groovy 脚本中工作，因为我对它了解不多。
这里写一个Groovy脚本的目的是提取聚合键对应的所有金额并求和，但目前我连标签元素和值都卡住了
下面是我正在使用的XML，保存在SOAPUI 属性中。我在 Groovy 脚本中解析它：

这是 groovy 脚本，它可以满足您的需求。
方法 #1 使用 XmlSlurper
即，使用可能的值之一搜索 aggregationKey 并找到相应 amount 的值并将它们相加。
//Define what key & possible values to filter
def filterMap = [aggregationKey:['INV_GROUP_Meterreading','INV_GROUP_Power']]
//Pass xmlString below, not added for saving space
def xml = new XmlSlurper().parseText(xmlString)
def result = filterMap.collect{ k,v -> xml.'**'.findAll{it.name() == k && it in v}*.parent()*.amount*.text()}.flatten().sum{it as Double}
log.info result
你可以快速在线试用这个demo
方法 #2 使用 xpath
请注意，用于检索所需金额和总和的正确 xpath 是 sum(//lines[aggregationKey[.='INV_GROUP_Meterreading' or .='INV_GROUP_Power']]/amount)
当然，如果有命名空间，那也需要处理。
脚本
import com.eviware.soapui.support.XmlHolder
//Pass xmlString, avoiding to save the space
def holder = new XmlHolder(xmlString)
def result = holder.getNodeValue("sum(//*:lines[aggregationKey[.='INV_GROUP_Meterreading' or .='INV_GROUP_Power']]/*:amount)") as Double
log.info result
