    <p>I need to develop an application that will read and understand text file in which I'll find a custom language that describe a list of operations (ie cooking recipe). This language has not been defined yet, but it will probably take one of the following shape :</p> <ul> <li><strong>C++ like code</strong></li> </ul> <p>(This code is randomly generated, just for example purpose) :</p> <pre><code>begin repeat(10) { bar(toto, 10, 1999, xxx); } result = foo(xxxx, 10); if(foo == ok) { ... } else { ... } end </code></pre> <ul> <li><strong>XML code</strong></li> </ul> <p>(This code is randomly generated, just for example purpose) :</p> <pre><code>&lt;recipe&gt; &lt;action name="foo" argument"bar, toto, xxx" repeat=10/&gt; &lt;action name="bar" argument"xxxxx;10" condition="foo == ok"&gt; &lt;true&gt;...&lt;/true&gt; &lt;false&gt;...&lt;/false&gt; &lt;/action&gt; &lt;/recipe&gt; </code></pre> <p>No matter which language will be chosen, there will have to handle simple conditions, loops.</p> <p>I never did such a thing but at first sight, it occurs to me that describing those operations into XML would be simplier yet less powerful.</p> <p>After browsing StackOverFlow, I've found some chats on a tool called "ANTLR"... I started reading "The Definitive ANTLR Reference" but since I never done that kind of stuff, I find it hard to know if it's really the kind of tool I need...</p> <p>In other words, what do I need to read a text file, interpret it properly and perform actions in my C# code. Those operations will interact between themselves by simple conditions like :</p> <ul> <li>If operation1 failed, I do operation2 else operation3.</li> <li>Repeat the operation4 10 times.</li> </ul> <p>What would be the best language to do describe those text file (XML, my own) ? What are the key points during such developments ?</p> <p>I hope I'm being clear :)</p> <p>Thanks a lot for your help and advices !</p>

    1. COI wouldn't say the XML is less powerful just more wordy. Once the C++ language is parsed into an expression tree it could easily be turned into XML without loss of power.

    2. COYeah, I'm afraid of encountering difficulties with loops, conditions, etc... As Moo-Juice said, I have trouble seeing XML as a language to describe logic... I see it more like a way of describin a static structre... Am I wrong ?

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.
