    <p>What I am doing is reading a <strong>xml</strong> file and trying to add a child node to a given <strong>xml</strong> file. But the problem is, it is not showing properly in the file here is the code: </p> <pre><code>xmlDocPtr doc; xmlNodePtr nodeptr=NULL , node = NULL , node_child =NULL; doc = xmlParseFile("Mainfile.xml"); if (doc == NULL ) { fprintf(stderr,"Document not parsed successfully. \n"); return; } nodeptr = xmlDocGetRootElement(doc); if (nodeptr == NULL) { fprintf(stderr,"empty document\n"); xmlFreeDoc(doc); return; } if (xmlStrcmp(nodeptr-&gt;name, (const xmlChar *) "story")) { fprintf(stderr,"document of the wrong type, root node != story"); xmlFreeDoc(doc); return; } node = xmlNewNode( NULL, BAD_CAST "Account" ); xmlNewProp(node, BAD_CAST "id", BAD_CAST "A001"); xmlAddChild(nodeptr , node); node_child = xmlNewChild(node, NULL, BAD_CAST "Country",BAD_CAST "US"); xmlAddChild(node,node_child); xmlAddChild(nodeptr , node); node_child = xmlNewChild(node, NULL, BAD_CAST "City", BAD_CAST "ABC"); xmlAddChild(node,node_child); xmlAddChild(nodeptr , node); node_child = xmlNewChild(node, NULL, BAD_CAST "ZIP",BAD_CAST "34040"); xmlAddChild(node,node_child); xmlAddChild(nodeptr , node); xmlSaveFile("Mainfile.xml", doc); xmlFree(doc); </code></pre> <p>And the structure of given xml file is </p> <pre><code>&lt; ?xml version="1.0"? &gt; &lt; Project &gt; &lt; author &gt;John Fleck&lt; /author &gt; &lt; datewritten &gt;June 2, 2002&lt; /datewritten &gt; &lt; keyword &gt;example keyword&lt; /keyword &gt; &lt; Account id = "A000" &gt; &lt; Country &gt;UK&lt; /Country &gt; &lt; City &gt;XYZ&lt; /City &gt; &lt; Zip &gt;67688&lt; /Zip &gt; &lt; /Account &gt; &lt; /Project &gt; </code></pre> <p>and after using my code the xml showing the content in below format </p> <pre><code>&lt; ?xml version="1.0"? &gt; &lt; Project &gt; &lt; author &gt;John Fleck&lt; /author &gt; &lt; datewritten &gt;June 2, 2002&lt;/datewritten&gt; &lt; keyword &gt;example keyword&lt; /keyword &gt; &lt; Account id = "A000" &gt; &lt; Country &gt;UK&lt; /Country &gt; &lt; City &gt;XYZ&lt; /City &gt; &lt; Zip &gt;67688&lt; /Zip &gt; &lt; /Account &gt; &lt; Account id = "A001" &gt;&lt; Country &gt;US&lt; /Country &gt;&lt; City &gt;ABC&lt; /City &gt;&lt; Zip &gt;34040&lt; /Zip &gt;&lt; /Account &gt;&lt; /Project &gt; </code></pre> <p>The main problem is it is not adding the child node with proper indentation.</p> <p>Can anyone suggest me what I'm doing wrong? </p>

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.
