copied!<ul> <li>Manual approach</li> </ul> <p>Well you could use a more classic approach of using a mapping in your fileformat (that is, if you have access to the spec (the content) of your files).</p> <p>You already give the perfect example of what your text should look like:</p> <pre><code>segment: 2A name: Aorta_Ascendens length: 2 radius: 1.47 wall_thickness: .164 young modulus: 4 compliance: 53.4 </code></pre> <p>What's the problem with that format ? So it gives better flexibility (safety) because you can check for sure that a member is what you expect to read. You could separate objects with a delimiter:</p> <pre><code>segment: 2A name: Aorta_Ascendens length: 2 radius: 1.47 wall_thickness: .164 young modulus: 4 compliance: 53.4 **@** segment: 2B name: Aorta_Ascendens length: 3 radius: 1.00 wall_thickness: .164 young modulus: 4 compliance: 53.4 </code></pre> <p>Use ifstream.readlines() to get an array of C++ style strings, which will help you parse using <code>find()</code> function (returns <code>string::npos</code> if not found).<br> In the Parse() function it involves iterating over the lines of the file, first, use <code>find</code> to look for <code>:</code> character, takes the left part using <code>substr</code> to check which member to assign the value (and how to parse, integer, enumeration ?...) and another <code>substr</code> with a little calculation (eg <code>size - posfound</code>) to take the right part, and put that into your <code>lexical_cast</code> of choice. Either <code>boost::lexial_cast</code> or <code>std::istringstream</code>.</p> <ul> <li>boost way</li> </ul> <p>Otherwise, you have the choice of using <code>boost::serialization</code> which will let you write only one super simple function to read this kind of formats. (cf annex)</p> <ul> <li>data binding (to xml, jason, ini...)</li> </ul> <p>Or more complex data binding frameworks like Code Synthesis XSD (Xerces?):<br> <a href="http://www.codesynthesis.com/products/xsd/" rel="nofollow">http://www.codesynthesis.com/products/xsd/</a></p> <ul> <li>Python !</li> </ul> <p>And even more simple, use python. you just have to do <code>eval()</code></p> <p>PS: Annex (with <code>boost::serialization</code>) taken from the doc :</p> <pre><code>class gps_position { private: friend class boost::serialization::access; // When the class Archive corresponds to an output archive, the // & operator is defined similar to <<. Likewise, when the class Archive // is a type of input archive the & operator is defined similar to >>. template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & degrees; ar & minutes; ar & seconds; } int degrees; int minutes; float seconds; public: gps_position(){}; gps_position(int d, int m, float s) : degrees(d), minutes(m), seconds(s) {} }; </code></pre> <p>isn't it stupid simple ? and its guaranteed to work. (well as long as you wrote the file with the same serializer).<br> refer to <a href="http://www.boost.org/doc/libs/1_55_0/libs/serialization/doc/index.html" rel="nofollow">http://www.boost.org/doc/libs/1_55_0/libs/serialization/doc/index.html</a></p>
