(CkPython) Demonstrates the ChilkatPath XML Method

Demonstrates how to use the ChilkatPath method. This example uses the XML sample file pigs.xml. The pigs.xml file contains this content:

Chilkat Python Downloads install with pip pip3 install chilkat or download... Python Module for Windows, MacOS, Linux, Alpine Linux, Solaris

import sys
import chilkat

xml = chilkat.CkXml()

success = xml.LoadXmlFile("qa_data/xml/pigs.xml")
if (success != True):
    print(xml.lastErrorText())
    sys.exit()

# Get the content of the "species" node for the 1st animal:

result = xml.chilkatPath("animal|species|*")
# Output should be "pot belly pig"
print(result)

# Get the content of the "type" node for the 2nd animal:
# Indexing begins at 0.  Therefore, the 2nd direct child having
# the tag "animal" is at index 1
result = xml.chilkatPath("animal[1]|type|*")
# Output should be "House Pig"
print(result)

# Find the pig having the name "Nigel" and display the
# birth date.  To do this, we'll navigate to the node having
# tag="name" with the exact content "Nigel", then navigate up, 
# and finally navigate back down to the "birth" node:
result = xml.chilkatPath("/C/name,Nigel|..|birth|*")
# Output should be "June, 1991"
print(result)

# Navigate to the 1st animal's picture and print the filename,
# description, and caption.
# The "$" updates the caller's internal pointer to reference
# the node that is the result of evaluating the path.
# An empty string is returned for success, and a NULL/nil/0
# pointer (reference) is returned on failure.  
result = xml.chilkatPath("animal|picture|$")
if (xml.get_LastMethodSuccess() != True):
    print("Failed to navigate to animal|picture.")
    sys.exit()

# Display the contents of the file/description/caption child nodes
print("Picture Info:")
print(xml.getChildContent("file"))
print(xml.getChildContent("description"))
print(xml.getChildContent("caption"))

# Return back to the root of the XML document:
xml.GetRoot2()

# Display the value of the "spay-neuter" attribute of the 1st animal:
print("----")
result = xml.chilkatPath("animal|gender|(spay-neuter)")
print(result)
