    <p>So I have to write a "duplicate checker" to compare two XMLs and see if they are the same (contain the same data). Now because they come from the same class and are generated form an XSD the structure the order of the elements inside will most likely be the same.</p> <p>The best way I can think of doing the duplicate check is to set up two dictionaries (dictLeft, dictRight) and saving the xpath#value as the key and the number of times it occurs. Something like this:</p> <p>Left:</p> <pre><code>{ 'my/path/to/name#greg': 1, 'my/path/to/name#john': 2, 'my/path/to/car#toyota': 1} </code></pre> <p>Right</p> <pre><code>{ 'my/path/to/name#greg': 1, 'my/path/to/name#bill': 1, 'my/path/to/car#toyota': 1} </code></pre> <p>Comparing these two dictionaries will give me a fairly accurate indication of whether or not these two XMLs are the same or not (there is the odd chance that I may get false results, but it is very remote).</p> <p>Does anyone else have a better idea? Maybe a function in ElementTree that I do not know about?</p> <p>EDIT: To better explain:</p> <pre><code>&lt;root&gt;&lt;person&gt;&lt;name&gt;Bob&lt;/name&gt;&lt;surname&gt;marley&lt;/surname&gt;&lt;/root&gt; </code></pre> <p>and</p> <pre><code>&lt;root&gt;&lt;person&gt;&lt;surname&gt;marley&lt;/surname&gt;&lt;name&gt;Bob&lt;/name&gt;&lt;/root&gt; </code></pre> <p>would be considered the same. I am ignoring attributes. The idea is to keep the code as simple as possible while not hampering performance too much.</p>

    1. COCan you better define the problem? What is your definition of "the same"? Can child elements be in arbitrary orders? Can different nestings of child elements be considered the same? Are the attributes important, etc. Also, what is your goal here? Performance? Correctness? Simplicity of code?

    2. CO"the same" meaning the data contained is the same, not necessarily the order. I am ignoring attributes.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
