How to extract value from xml file using grep

Question

I have a XML file as follow

<?xml version="1.0" ?>
<coverage branch-rate="0" branches-covered="0" branches-valid="0" complexity="0" line-rate="0.7606" lines-covered="270" lines-valid="355" timestamp="1595999208833" version="5.2.1">
    <!-- Generated by coverage.py: https://coverage.readthedocs.io -->
    <!-- Based on https://raw.githubusercontent.com/cobertura/web/master/htdocs/xml/coverage-04.dtd -->
    <sources>
        <source>/home/lebanon/appt</source>
    </sources>
    <packages>
        <package branch-rate="0" complexity="0" line-rate="1" name="application">
            <classes>
                <class branch-rate="0" complexity="0" filename="application/__init__.py" line-rate="1" name="__init__.py">
                    <methods/>
                    <lines>
                        <line hits="1" number="23"/>
                    </lines>
                </class>
            </classes>
        </package>
</coverage>

I want to retrieve line-rate value inside the tag. How can this be achieved using grep ?

IMHO experts always advice to use tools like xmlstarlet, xmlint for dealing with xml files. Because they understand xmls well. So please do let us know if you have these tools available in your system? If not could you please get them? Because depending upon that only we may receive answers, cheers. — RavinderSingh13, Jul 29 '20 at 05:29

You should not parse xml with grep (although you can), so with xmllint you can do this

xmllint --xpath '/coverage/@line-rate' file.xml
