Re: [Tutor] Importing XML files.
Peter and Alan,
Peter, Thanks for the information. The library did the trick and I can get
access to the XML content.
Alan, thanks for the explanation of the tree structure. I was aware of this
already for HTML and XML. Just didn't understand the terminology used from the
XML library. The tutorials I have viewed didn't explain this information. I
will continue investigating. The library provided has addressed my concerns for
now.

You may be lucky in that you can avoid the hard way outlined by Alan --
Python's stdandard library includes a module that handles Apple's plist format.
I tried your sample, and the module seems to turn it into nested
dicts:
>>> import plistlib, pprint
>>> with open("sample.xml", "rb") as f:
... data = plistlib.load(f)
...
>>> pprint.pprint(data, width=70)
{'Application Version': '12.8.0.150',
'Date': datetime.datetime(2019, 1, 14, 3, 56, 30),
'Features': 5,
'Library Persistent ID': 'F2D33B339F0788F0', 'Major Version': 1, 'Minor
Version': 1, 'Music Folder': 'file:///Volumes/Itunes/iTunes/iTunes%20Media/',
'Show Content Ratings': True,
'Tracks': {'6493': {'Album': 'In Her Sights (Unabridged)',
'Album Artist': 'Robin Perini',
'Artist': 'Robin Perini',
'Artwork Count': 1,
'Bit Rate': 64,
'Comments': "Jasmine 'Jazz' Parker, "
'Jefferson County SWAT’s only '
'female sniper, can thread the '
'eye of a needle with a bullet. '
'But she carries with her a '
'secret from her past', [snip]
>>> data["Date"].isoformat()
'2019-01-14T03:56:30'
>>> list(data["Tracks"].values())[0]["Artist"]
'Robin Perini'
Looks good, except for the mojibake -- but that was already in your email.

You really need to find a tutorial on XML (And maybe even start with one on HTML?) To parse out the information from an XML file, even using a parser like etree, requires that you understand the structure of the file. And that includes really understanding the terminology. In very simple terms an XML file (or more correctly a "document") is a tree structure. It starts with a parent node then that has child nodes. Each child may have children of its own ad infinitum. Each node is identified by a pair of tags which are simply names between angle brackets - for example There is a start and closing tag, the closing one having a '/' at the start. Between the tags is the text (which may include more tags for child nodes). tags can also include attributes which are names inside the opening tags brackets, often with an assigned value. The rules governing what constitutes a valid tag or attribute and which tags can be nested within which others are all defined in a definition file, often called a schema or DTD file. There is a standard header that tells the reader where to find the schema. You might also see comments which are just notes to explain whats going on and contain no actual data... Here is a meaningless pseudocode example: Some text here Child2 text here Text here on same line More child2 text Text for subchild Finishing off child2 text... More text here, could be lorts of it over many lines For more than that google XML tutorial...

[Tutor] Importing XML files.
All, I am trying to import ITunes XML files. I have been doing some reading and I am somewhat confused with some XML terminology. What is: Tag – I think it is the in the itunes library file. Text = The text between the Attrib -- don’t know. If I am correct in my thinking. If you look up all the tags using the xml module. How do you then isolate all the name text? I do not have any working code at this present time. I have been playing with the xml methods and reading some example tutorials. But I am stumped with the above terminology which is a small road block. Below is an example extract of my xML ITunes to see if this helps.

All we can say from this is that you are passing the correct variable to mapInput(). But what does mapUInput() do? Show us that code too. And what does mapLocation do with the return value from mapInput()? We need to see that code too. > ... Hoewer it does work if I input a string > without the currLocation variable. That probably makes sense to you but makes no sense to us. How can it "work" if you remove the variable that you are saying doesn't work? Maybe you need to explain what you are trying to achieve? -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
