loxun 0.8

loxun is a Python library that can be used to write large output in XML using Unicode and namespaces. Of course you can also use it for small XML output with plain 8 bit strings and no namespaces.<br /><br />Here is a very basic example. First you have create an output stream. In many cases this would be a file, but for the sake of simplicity we use a StringIO here:<br /><br /> >>> from StringIO import StringIO<br /> >>> out = StringIO()<br /> >>> xml = XmlWriter(out)<br /><br />Now write the content:<br /><br /> >>> xml.addNamespace("xhtml", "http://www.w3.org/1999/xhtml")<br /> >>> xml.startTag("xhtml:html")<br /> >>> xml.startTag("xhtml:body")<br /> >>> xml.text("Hello world!")<br /> >>> xml.tag("xhtml:img", {"src": "smile.png", "alt": ":-)"})<br /> >>> xml.endTag()<br /> >>> xml.endTag()<br /> >>> xml.close()<br /><br />And the result is:<br /><br /> >>> print out.getvalue().rstrip("rn")<br /> < ?xml version="1.0" encoding="utf-8"? ><br /> < xhtml:html xlmns:xhtml="http://www.w3.org/1999/xhtml" ><br /> < xhtml:body ><br /> Hello world!<br /> < xhtml:img alt=":-)" src="smile.png" / ><br /> < /xhtml:body ><br /> < /xhtml:html ><br /><br />Here are some key features of "loxun":<br /><br />?*A* small memory foot print: the document is created on the fly by writing to an output stream, no need to keep all of it in memory.<br />?*A* easy to use namespaces: simply add a namespace and refer to it using the standard namespace:tag syntax.<br />?*A* mix unicode and string: pass both unicode or plain 8 bit strings to any of the methods. Internally loxun converts them to unicode, so once a parameter got accepted by the API you can rely on it not causing any messy UnicodeError trouble.<br />?*A* automatic escaping: no need to manually handle special characters such as < or & when writing text and attribute values.<br />?*A* robustness: while you write the document, sanity checks are performed on everything you do. Many silly mistakes immediately result in an XmlError, for example missing end elements or references to undeclared namespaces.<br />?*A* open source: distributed under the GNU Lesser General Public License 3 or later.<br /><br />loxun-0.8.zip#md5=a0b0891c0f47cf638727302fa76491f2
