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:

//  Get the content of the "species" node for the 1st animal:
string result;
result = xml.ChilkatPath("animal|species|*");
//  Output should be "pot belly pig"
textBox1.Text += result + "\r\n";

//  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"
textBox1.Text += result + "\r\n";

//  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"
textBox1.Text += result + "\r\n";

//  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 (result == null ) {
    textBox1.Text += "Failed to navigate to animal|picture." + "\r\n";
    return;
}

//  Display the contents of the file/description/caption child nodes
textBox1.Text += "Picture Info:" + "\r\n";
textBox1.Text += xml.GetChildContent("file") + "\r\n";
textBox1.Text += xml.GetChildContent("description") + "\r\n";
textBox1.Text += xml.GetChildContent("caption") + "\r\n";

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

//  Display the value of the "spay-neuter" attribute of the 1st animal:
textBox1.Text += "----" + "\r\n";
result = xml.ChilkatPath("animal|gender|(spay-neuter)");
textBox1.Text += result + "\r\n";
