+<title>Building XML tree using libxml2 API</title>
+
+<para>
+One of the ways building a xml tree into an 
+SOAP envelope is to use directly the libxml2 API.
+You can obtain the xmlNodePtr of an envelope
+with the SoapEnv structure.
+</para>
+
+<synopsis>
+typedef struct _SoapEnv
+{ 
+  xmlNodePtr root; 
+  xmlNodePtr cur;
+}SoapEnv;
+</synopsis>
+
+<para>
+Here is "root" your xml node to &lt;SOAP-ENV:Envelope&gt;.
+</para>

+
+<para>
+You can build a xml tree using following functions
+</para>
+
+<synopsis>
+xmlNodePtr 
+soap_env_add_item(SoapEnv* env, const char *type, 
+		  const char *name, const char *value);
+xmlNodePtr 
+soap_env_add_itemf(SoapEnv* env, const char *type, 
+		  const char *name, const char *value, ...);
+xmlNodePtr 
+soap_env_push_item(SoapEnv *env, const char *type,
+		   const char *name);
+void
+soap_env_pop_item(SoapEnv* env);
+</synopsis>
+
+<para>
+soap_env_add_itemf() does the same thing like soap_env_add_item()
+but with a C style argument list. (Max buffer for value is 1054)
