You need to use the firstChild.nodeValue in order to get the value of the node:

from xml.dom.minidom import parse

dom = parse("data.xml")
for node in dom.getElementsByTagName('CallsPerMinute'):
    print(node.firstChild.nodeValue)

Also, your xml needs your tags closed:

<?xml version="1.0" encoding="UTF-8"?>
<BusinessTransactions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                      Controller="http://10.43.11.143:8090/controller/rest"
                      GenerationTime="2015-12-30T09:47:46.817698-03:00" xsi:noNamespaceSchemaLocation="bt_metrics.xsd">
    <BusinessTransaction>
        <ApplicationName>Portales</ApplicationName>
        <BusinessTransactionName>APP</BusinessTransactionName>
        <AverageResponseTime>142</AverageResponseTime>
        <CallsPerMinute>169</CallsPerMinute>
        <ErrorsPerMinute>15</ErrorsPerMinute>
    </BusinessTransaction>
</BusinessTransactions>
