消除<?xml version="1.0" ?>使用 xml.dom.minidom

Question

I am generating XML files using xml.dom.minidom . Every time I generate a file on the very row there appears <?xml version="1.0" ?> and the generated file looks like this:

<?xml version="1.0" ?> 
 <Root>
     data 
 </Root>

is not there anyway so have an output without and my output should look like

 <Root>
      data 
 </Root>

Answer 1

If you are happy just to trim the first line from the file, use this code;

f = open( 'file.txt', 'r' )
lines = f.readlines()
f.close()

f = open( 'file.txt'.'w' )
f.write( '\n'.join( lines[1:] ) )
f.close()

Answer 2

The best solution I found was to write out .childNodes[0] , ie write out:

doc.childNodes[0].toprettyxml()

to the file, which will omit the xml version tag.

Answer 3

这完成了 old_data 是要剥离的 xml 的工作

new_data = old_data[old_data.find("?>")+2:]
