  1. POWriting after a Node with XmlWriter
    text
    copied!<p>I'm low on documentation about XmlReader, I have an structure for a node that looks like this</p> <pre><code>&lt;person key="17000000"&gt; &lt;name&gt;John Doe&lt;/name&gt; &lt;age&gt;23&lt;/age&gt; &lt;/person&gt; </code></pre> <p>And a file containing a group of people, that must be ordered by key.</p> <pre><code>&lt;group&gt; &lt;person key="123"&gt; ... &lt;/person&gt; &lt;person key="130"&gt; ... &lt;/person&gt; &lt;/group&gt; </code></pre> <p>I'm writing a function that inserts them in the correct order but I'm having issues telling the place where a new person must be inserted. So far I'm doing the following:</p> <ol> <li>Create reader for the group file and a writer for a temporary file.</li> <li>Read until reader's key is bigger than request's key, write nodes to temp while reading.</li> <li>Write the request structure to the temp file.</li> <li>Read the rest of the file and write to the temp file.</li> <li>Replace the group file with the temp file.</li> </ol> <p>So far is not working, and the file is looking like this (if 130 is inserted after 123):</p> <pre><code>&lt;group&gt; &lt;group&gt; &lt;person key="123"&gt; ... &lt;/person&gt; &lt;/group&gt; &lt;person key="130"&gt; ... &lt;/person&gt; &lt;/group&gt; </code></pre> <p>Is there a general way to insert structures in Xml files? </p> <p>I have some restrictions, like, I must use XmlReader and XmlWriter and memory usage is limited, so I can work with a reader and writer pointer and that's it.</p> <p>I appreciate your help!</p>
