### __init__(self, name_or_xmlnode, from_jid=None, to_jid=None, stanza_type=None, stanza_id=None, error=None, error_cond=None, stream=None) (Constructor) | source code
Initialize a Stanza object. Parameters: `name_or_xmlnode` (: `unicode` or `libxml2.xmlNode` or Stanza) - : XML node to be wrapped into the Stanza object or other Presence object to be copied. If not given then new presence stanza is created using following parameters. `from_jid` (: JID) - : sender JID. `to_jid` (: JID) - : recipient JID. `stanza_type` (: `unicode`) - : staza type: one of: "get", "set", "result" or "error". `stanza_id` (: `unicode`) - : stanza id -- value of stanza's "id" attribute. If not given, then unique for the session value is generated. `error` (: pyxmpp.error.StanzaErrorNode) - : error object. Ignored if stanza_type is not "error". `error_cond` (: `unicode`) - : error condition name. Ignored if stanza_type is not "error" or error is not None.

### add_content(self, content) | source code
Add an XML node to the stanza's payload. Parameters: `content` - : XML node to be added to the payload. Types: `content`: `libxml2.xmlNode`, UTF-8 `str` or unicode, or an object with "as_xml()" method.

### add_new_content(self, ns_uri, name) | source code
Add a new XML element to the stanza payload. Parameters: `ns_uri` (: `str`) - : XML namespace URI of the element. `name` (: `str` or `unicode`) - : element name.

### get_error(self) | source code
Get stanza error information. Returns: pyxmpp.error.StanzaErrorNode object describing the error.

### get_from(self) | source code
Get "from" attribute of the stanza. Returns: JID value of the "from" attribute (sender JID) or None.

### get_from_jid(self) | source code
Get "from" attribute of the stanza. Returns: JID value of the "from" attribute (sender JID) or None.

### get_id(self) | source code
Get "id" attribute of the stanza. Returns: `unicode` value of the "id" attribute (stanza identifier) or None.

### get_stanza_id(self) | source code
Get "id" attribute of the stanza. Returns: `unicode` value of the "id" attribute (stanza identifier) or None.

### get_stanza_type(self) | source code
Get "type" attribute of the stanza. Returns: `unicode` value of the "type" attribute (stanza type) or None.

### get_to(self) | source code
Get "to" attribute of the stanza. Returns: JID value of the "to" attribute (recipient JID) or None.

### get_to_jid(self) | source code
Get "to" attribute of the stanza. Returns: JID value of the "to" attribute (recipient JID) or None.

### get_type(self) | source code
Get "type" attribute of the stanza. Returns: `unicode` value of the "type" attribute (stanza type) or None.

### serialize(self) | source code
Serialize the stanza into an UTF-8 encoded XML string. Returns: `str` serialized stanza.

### set_content(self, content) | source code
Set stanza content to an XML node. Parameters: `content` (: `libxml2.xmlNode` or unicode, or UTF-8 `str`) - : XML node to be included in the stanza.

### set_from(self, from_jid) | source code
Set "from" attribute of the stanza. Parameters: `from_jid` (: JID) - : new value of the "from" attribute (sender JID).

### set_id(self, stanza_id) | source code
Set "id" attribute of the stanza. Parameters: `stanza_id` (: `unicode`) - : new value of the "id" attribute (stanza identifier).

### set_new_content(self, ns_uri, name) | source code
Set stanza payload to a new XML element. Parameters: `ns_uri` (: `str`) - : XML namespace URI of the element. `name` (: `str` or `unicode`) - : element name.

### set_to(self, to_jid) | source code
Set "to" attribute of the stanza. Parameters: `to_jid` (: JID) - : new value of the "to" attribute (recipient JID).

### set_type(self, stanza_type) | source code
Set "type" attribute of the stanza. Parameters: `stanza_type` (: `unicode`) - : new value of the "type" attribute (stanza type).

### xpath_eval(self, expr, namespaces=None) | source code
Evaluate an XPath expression on the stanza XML node. The expression will be evaluated in context where the common namespace (the one used for stanza elements, mapped to 'jabber:client', 'jabber:server', etc.) is bound to prefix "ns" and other namespaces are bound accordingly to the `namespaces` list. Parameters: `expr` (: `unicode`) - : XPath expression. `namespaces` (: `dict` or other mapping) - : mapping from namespace prefixes to URIs.
