Xpath in Python . Getting SyntaxError("invalid predicate")

Question

import xml.etree.ElementTree as ET
tree = ET.parse('test.xml')

xpathobjects = tree.findall(".//BuildingNodeBase[name = 'Building name']")

I am wanting to pull a BuildingNodeBase with a child tag name that has value Building name.

But Getting:

SyntaxError("invalid predicate")

The XPath support in ElementTree is limited, but your type of expression is supported. It's just that you need to remove the extra spaces around the =:

.//BuildingNodeBase[name='Building name']

I use lxml but I guess you can adopt this for your use:

from lxml import etree

tree = etree.parse('test.xml')

xpathobjects = tree.xpath(".//BuildingNodeBase[@name = 'Building name']")
