Processing Instructions

[Andrew Mercer]

I am using BeautifulSoup to parse DITA (xml) files and I am experiencing an issue with processing instructions. Unfortunately I don't understand xml well enough to know if this is a bug with BeautifulSoup or an error in the xml source.

Running the following script:

    import bs4

    xml = '<?xml version="1.0" encoding="utf-8"?><p>Test xml with PI <?dtall break="line"?>a..z<?dtall break="line"?></p>'

    soup = bs4.BeautifulSoup(xml, 'xml')

    str(soup)

Produces the following output:

    '<?xml version="1.0" encoding="utf-8"?>\n<p>Test xml with PI <?dtall break="line">a..z<?dtall break="line"></p>'

The closing ? has been stripped from the <?dtall ... ?> tags.

Any help/advice will be appreciated.
