This small program: from lxml.html import tostring, fromstring e = fromstring(”’ <html><head> <link href="/comments.css"

This small program:

from lxml.html import tostring, fromstring
e = fromstring('''
<html><head>
        <link href="/comments.css" rel="stylesheet" type="text/css">
        <link href="/index.css" rel="stylesheet" type="text/css">
    </head>
    <body>
        <span></span>
        <span></span>
    </body>
</html>''')

print (tostring(e, encoding=str)) #unicode on python 2

will print:

<html><head><link href="/comments.css" rel="stylesheet" type="text/css"><link
href="/index.css" rel="stylesheet" type="text/css"></head><body>
        <span></span>
        <span></span>
    </body></html>

The spaces and line breaks in head removed.
This happens even if we place the two <link> elements in <body>.
It seems blank text nodes (\s*) between head elements are removed.

How I can preserve spaces and line breaks between <link>s? (I expect output to be exactly same as input)

    Finally, I used html5lib to parse html and generate lxml like tree with it.

    parser = html5lib.HTMLParser(tree=html5lib.getTreeBuilder("lxml"), namespaceHTMLElements=False)
