Thank you for writing to us...

XML carefully places the file or other data source and the abstract model of the XML document away. If you want to determine whether an XML document has been modified to compare two XML documents for equality, it can be inconvenient to compare a digital signature directly, such as a test package, or for security purpos
Modify xml files in DOS batch processing and xml files in dos batch processing
In the past, batch processing and dos were only at the cd ping ipconfig level. I thought it should be very easy to change the file. If I read the file and replace it with another one, I will not write it back. Baidu's example will be changed, that is not a matter of minutes. It is much more complicated than you think.
