Xpath Support in Edge browser

Hello Team,

We are facing an issue in Edge browser regarding xpath support.

My DOM element which I need to detect using xPath has 2 css classes applied to it.

<ul>

<li class="myClass1 myClass2"></li>

</ul>

If I mention only one class name in the xPath, it works in Edge browser e.g.

".//*[contains(@class,'myClass1')]"

but if I mention both class names (space separated) it doesn't work e.g

".//*[contains(@class,'myClass1 myClass2')]"

although it works well in all other browsers.
