  1. POWhy doesn't boost::serialization check for tag names in XML archives?
    text
    copied!<p>I'm starting to use boost::serialization on XML archives. I can produce and read data, but when I hand-modify the XML and interchange two tags, it "fails to fail" (i.e. it proceeds happily).</p> <p>Here's a small, self-complete example showing what I see:</p> <pre><code>#include &lt;iostream&gt; #include &lt;fstream&gt; #include &lt;boost/archive/xml_oarchive.hpp&gt; #include &lt;boost/archive/xml_iarchive.hpp&gt; #include &lt;boost/serialization/nvp.hpp&gt; #include &lt;boost/serialization/split_member.hpp&gt; using namespace std; int main (void) { boost::archive::xml_oarchive oa (cout); static const string producer = "XXX", version = "0.0.1"; oa &lt;&lt; boost::serialization::make_nvp ("producer", producer); oa &lt;&lt; boost::serialization::make_nvp ("producer_version", version); } </code></pre> <p>This writes XML to standard output, which contains:</p> <pre><code>&lt;producer&gt;XXX&lt;/producer&gt; &lt;producer_version&gt;0.0.1&lt;/producer_version&gt; </code></pre> <p>Now, I replace all the code in the main function with a reader:</p> <pre><code> boost::archive::xml_iarchive ia (cin); string producer, version; ia &gt;&gt; boost::serialization::make_nvp ("producer", producer); ia &gt;&gt; boost::serialization::make_nvp ("producer_version", version); cout &lt;&lt; producer &lt;&lt; " " &lt;&lt; version &lt;&lt; endl; </code></pre> <p>which works as expected when fed the previous output (outputs "XXX 0.0.1"). If, however, I feed it XML in which I changed the order of the two lines "producer" and "producer_version", it still runs and outputs "0.0.1 XXX".</p> <p>Thus, it fails to recognize that the tags don't have the expected names, and just proceed. I would have expected it to thrown a <code>xml_archive_parsing_error</code> exception, as indicated in <a href="http://www.boost.org/doc/libs/1_42_0/libs/serialization/doc/exceptions.html#xml_archive_tag_mismatch" rel="nofollow noreferrer">the doc</a>.</p> <p>Does someone here have experience with that? What I am doing wrong?</p>
