How can you use Msxml to read XML files from the web in PB8?

In PB8, you can use the MSXML2.XMLHTTP object in the Msxml object library to read XML files from the web. Here is a simple example code:

// 定义变量
OLEObject lole_xmlhttp
OLEObject lole_xml

// 创建MSXML2.XMLHTTP对象
lole_xmlhttp = CREATE OLEObject
lole_xmlhttp.ConnectToNewObject("MSXML2.XMLHTTP")

// 发送HTTP请求获取XML文件
lole_xmlhttp.open("GET", "http://example.com/sample.xml", FALSE)
lole_xmlhttp.send()

// 读取返回的XML数据
IF lole_xmlhttp.status = 200 THEN
    // 创建MSXML2.DOMDocument对象
    lole_xml = CREATE OLEObject
    lole_xml.ConnectToNewObject("MSXML2.DOMDocument")

    // 加载XML数据
    lole_xml.loadXML(lole_xmlhttp.responseText)

    // 处理XML数据
    IF lole_xml.parseError.errorCode <> 0 THEN
        MessageBox("Error", lole_xml.parseError.reason)
    ELSE
        // 在这里可以通过lole_xml对象访问和处理XML数据
        // 例如，获取根节点的名称
        String ls_rootNodeName
        ls_rootNodeName = lole_xml.documentElement.nodeName

        MessageBox("Root Node", ls_rootNodeName)
    END IF
ELSE
    MessageBox("Error", "Failed to retrieve XML data.")
END IF

// 释放对象
DESTROY lole_xmlhttp
DESTROY lole_xml

Please note that the above example is just a basic demonstration of reading an XML file, further processing and parsing may be required based on specific needs in real-world applications.
