Visual FoxPro

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:
Visual FoxPro

LOCAL lnSuccess
LOCAL loXml
LOCAL lcResult

lnSuccess = 0

loXml = CreateObject('Chilkat.Xml')

lnSuccess = loXml.LoadXmlFile("qa_data/xml/pigs.xml")
IF (lnSuccess <> 1) THEN
    ? loXml.LastErrorText
    RELEASE loXml
    CANCEL
ENDIF

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

lcResult = loXml.ChilkatPath("animal|species|*")
* Output should be "pot belly pig"
? lcResult

* 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
lcResult = loXml.ChilkatPath("animal[1]|type|*")
* Output should be "House Pig"
? lcResult

* Find the pig having the name "Nigel" and display the
* birth date.  To do this, we&apos;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:
lcResult = loXml.ChilkatPath("/C/name,Nigel|..|birth|*")
* Output should be "June, 1991"
? lcResult

* Navigate to the 1st animal&apos;s picture and print the filename,
* description, and caption.
* The "$" updates the caller&apos;s internal pointer to reference
* the node that is the result of evaluating the path.
* An empty string is returned for success, and a NULL/nil/0
* pointer (reference) is returned on failure.  
lcResult = loXml.ChilkatPath("animal|picture|$")
IF (loXml.LastMethodSuccess <> 1) THEN
    ? "Failed to navigate to animal|picture."
    RELEASE loXml
    CANCEL
ENDIF

* Display the contents of the file/description/caption child nodes
? "Picture Info:"
? loXml.GetChildContent("file")
? loXml.GetChildContent("description")
? loXml.GetChildContent("caption")

* Return back to the root of the XML document:
loXml.GetRoot2()

* Display the value of the "spay-neuter" attribute of the 1st animal:
? "----"
lcResult = loXml.ChilkatPath("animal|gender|(spay-neuter)")
? lcResult

RELEASE loXml
