Remove namespace prefix with sed

Question

I want to convert this piece of xml:

  
    Apples
    Bananas
           


        

Answer 1

Here's how you could do it with hxpipe and hxunpipe from the W3C HTML-XML-utils (packaged for many distributions):

$ hxpipe infile | sed 's/^\([()]\)v1:/\1/g' | hxunpipe

  

    
Apples
    
Bananas
  

hxpipe parses XML/HTML and turns it into an awk/sed-friendly line based format:

$ hxpipe infile
(v1:table
-\n  
(v1:tr
-\n    
(v1:td
-Apples
)v1:td
-\n    
(v1:td
-Bananas
)v1:td
-\n  
)v1:tr
-\n
)v1:table
-\n

where lines starting with ( and ) are opening and closing tags, so removing the first v1: from lines starting with ( or ) (which is what the sed command above does) achieves the desired effect. Notice that text lines start with a -, so there can't be any false positives.
