问题
I am trying to use JMeter XPath Assertion on a tag value as below with XPath assertion command:
//m:CurrencyNameResul/text() = Pounds
Webservice Response:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<m:CurrencyNameResponse xmlns:m="http://www.oorsprong.org/websamples.countryinfo">
<m:CurrencyNameResult>Pounds</m:CurrencyNameResult>
</m:CurrencyNameResponse>
</soap:Body>
</soap:Envelope>
I am getting error
prefix must resolve to a namespace
and after referring to JMeter manual below:
NAMESPACES As a work-round for namespace limitations of the Xalan XPath parser implementation on which JMeter is based, you can provide a Properties file which contains mappings for the namespace prefixes:
prefix1=Full Namespace 1
prefix2=Full Namespace 2
…
You reference this file in jmeter.properties file using the property:
xpath.namespace.config
I don't get it, so my questions are:
- what should be the content of Properties file?
- where to put its path?
回答1:
Here is how to proceed:
Create in jmeter/bin folder a file named namespaces.properties containing:
m=http://www.oorsprong.org/websamples.countryinfo
In user.properties set:
xpath.namespace.config=namespaces.properties
Finally fix your assertion to contain:
//m:CurrencyNameResult = 'Pounds'
And check "Use Namespaces"
To end up with:
回答2:
You can amend your XPath query to use name() function like:
(//*[name() = 'm:CurrencyNameResult'])/text()
and you will not have to mess up with amending properties, restarting JMeter, etc.
Moreover if you go for local-name() function instead you will not have to include the namespace prefix into your query:
(//*[local-name() = 'CurrencyNameResult'])/text()
