How to check if path in xpath exists?

This code successfully checks if xpath if a single element exists in xpath:

x = root.xpath("boolean(//*[contains(local-name(), 'bar')])", namespaces=lnamespaces)
print("xx ", x)

But I need to check if a path like foo/bar is exists. I tried:

x = root.xpath("boolean(//*[contains(local-name(), 'foo/bar')])", namespaces=lnamespaces)
print("xx ", x)

However, the code above evaluates to false even if the foo/bar path exists.

Code:

from lxml import etree

mystr = """
<some>
    <foo>
        <bar>
        </bar>
    </foo>

    <baz>
    </baz>
<some>  
"""
etxml = etree.HTML(mystr)

result = etxml.xpath("boolean(//*[contains(local-name(), 'foo/bar')])")
print("result: ", result)

I'm not sure if this is what you need, but I'm afraid the only way I could get there is like this:

tree_struct = etree.ElementTree(etxml)
for e in etxml.iter('bar'):
   print('/foo/bar' in tree_struct.getpath(e))

Output:

True
