Unable to validate pom.xml of a mule application in SonarQube - maven

Question

I am using SonarQube to validate artifactId, modelVersion etc in pom.xml file for a mule application.To validate these nodes, I have build some rules in SonarQube.but seems,POM rules are not working.Here is my pom xml and code rules.
<rule id ="2" name="Pom Model Version should be 4.0.0"
description="Pom Model Version should be 4.0.0"
severity="MAJOR" type="code_smell">
//*[local-name()='project']/*[local-name()='modelVersion']= '4.0.0'
</rule>
<rule id="3" name="Application Name is too long ok"
description="Application Name is too long, give a proper name"
severity="MAJOR" applies="application" type="code_smell">
string-length(//*[local-name()='project' ]/*[local-name()='artifactId'])>20
</rule>
<rule id ="4" name="Mule Runtime Version should be 4.2.0"
description="Mule Runtime Version should be 4.2.0"
severity="MAJOR" type="code_smell">
//*[local-name()='project']/*[local-name()='properties']/*[local-name()='app.runtime']= '4.2.0'
</rule>

My other rules to validate other xml files are working but above three rules are not working as expected.
