1.XML例子：<?xml version="1.0" encoding="GBK"?>
<root><head><code>1</code>
<message>数据下载成功！</message>
<rownum>1</rownum></head><body>
<DrvZp id="0">
<zpStr>/9j/4AAQSkZJRgABAQAAAAAAAAD/2w......</zpStr>
</DrvZp>
</body></root>
2.memo1.Text:=a.DocumentElement.ChildNodes['body'].ChildNodes['DrvZp'].ChildNodes
['zpStr'].Text;
3.Memo1中的文本为%2F9j%,而实际应为/9i/,文本中还有其它的错误,怎么解决,谢谢
