Difficulty Creating Lxml Element Subclass

I’m trying to create a subclass of the Element class. I’m having trouble getting started though. from lxml import etree try: import docx except ImportError: from docx i

Solution 1:

I don't really get why you want to use a separate class named File.

As Michael0x2a said, you did'nt put a document tag, so it won't work (I don't think Word 2007 can read your file too)

But here is the corrected code:

from lxml import etree
try:
    import docx
except ImportError:
    from docx import docx

classFile(object):
    defmakeelement(tagname, tagtext=None, nsprefix='w', attributes=None,
                    attrnsprefix=None):
        '''Create an element & return it'''# Deal with list of nsprefix by making namespacemap
        namespacemap = Noneifisinstance(nsprefix, list):
            namespacemap = {}
            for prefix in nsprefix:
                namespacemap[prefix] = nsprefixes[prefix]
            # FIXME: rest of code below expects a single prefix
            nsprefix = nsprefix[0]
        if nsprefix:
            namespace = '{'+nsprefixes[nsprefix]+'}'else:
            # For when namespace = None
            namespace = ''
        newelement = etree.Element(namespace+tagname, nsmap=namespacemap)
        # Add attributes with namespacesif attributes:
            # If they haven't bothered setting attribute namespace, use an empty# string (equivalent of no namespace)ifnot attrnsprefix:
                # Quick hack: it seems every element that has a 'w' nsprefix for# its tag uses the same prefix for it's attributesif nsprefix == 'w':
                    attributenamespace = namespace
                else:
                    attributenamespace = ''else:
                attributenamespace = '{'+nsprefixes[attrnsprefix]+'}'for tagattribute in attributes:
                newelement.set(attributenamespace+tagattribute,
                               attributes[tagattribute])
        if tagtext:
            newelement.text = tagtext
        return newelement

    def__init__(self):
        super(File,self).__init__()
        self.document = self.makeelement('document')
        self.document.append(self.makeelement('body'))


f = File()
relationships = docx.relationshiplist()
title    = 'File' 
subject  = 'A very special File'
creator  = 'Me'
keywords = ['python', 'Office Open XML', 'Word']
coreprops = docx.coreproperties(title=title, subject=subject, creator=creator,
    keywords=keywords)
appprops = docx.appproperties()
contenttypes = docx.contenttypes()
websettings = docx.websettings()
wordrelationships = docx.wordrelationships(relationships)
docx.savedocx(f.document, coreprops, appprops, contenttypes, websettings,
wordrelationships, 'file.docx')
