This post is a quick reply to the post RSS Is Dying, and You Should Be Very Worried. I really like rss reader. I have a lot of subscriptions to blogs.

Memory Efficient XML Processing not only with DOM
How can I efficiently parse large xml files which can be several GB large? With SAX? Hmmh, well, yes: you can! But this is somewhat ugly. If you prefer a better maintable approach you should definitely try joost which does not load the entire xml file into memory but is quite similar to xslt. But … Continue reading »
Xvantage – Yet Another Xml Serializer!
In one of my last posts I listed some xml serializers and binding tools. After trying XStream, JAXB, XmlEncoder, Apache Digester and X2JB I decided to create another one: xvantage! Why yet another xml tool? To make it clear: At the moment xvantage is in its early stage (one week old) and I hacked it … Continue reading »

Object Oriented, Relational Databases and XML
A long time I invested to explore the project called Datanucleus where you can use object oriented DBs like db4o, relational DBs like derby or just XML files as datasource! Thats fantastic and open source . You can find more implementations of JDO here. Other resources: Derby is a good database, which could pass ACID … Continue reading »
No OOXML
OOXML is now ISO standard! OOXML will divide the (internet) communication into a Microsoft-world and the rest. With the doc-format MS started the ‘way of division’ and now they will be successful!? “Finally I call on users all around the world to look to Norway and follow the example we have set. Raise a storm … Continue reading »
Relax NG
For my open source timetabling application (gstpl) I want to create a file format. There are some standard timetabling formats, but none of them is easy and general. I decided to use a schema to validate the created xml file. Checking the well-formedness is easy, but for validation you need to define a grammer, i.e.define … Continue reading »
