Assuming the tag value refers to the text content of the tag, the following steps can be taken to obtain the value of a tag using an absolute XML path and XPath:
Here is an example using Python and the lxml library:
from lxml import etree
# Create an XML document object
xml_doc = etree.parse("example.xml")
# Construct the XPath expression with an absolute path
xpath_expr = "/root/element/subelement"
# Append "/text()" to retrieve the tag value
xpath_expr += "/text()"
# Use the evaluate() method to select the tag and retrieve its value
tag_value = xml_doc.xpath(xpath_expr)[0]
print(tag_value) # Output: "Tag Value"
In this example, the XPath expression "/root/element/subelement/text()" selects the "subelement" tag within the "element" tag within the "root" tag, and retrieves its text content ("Tag Value").
