[SIXX] feedback

Hi Masashi, I am currently developing a new Smalltalk Wiki implementation (http://scgwiki.iam.unibe.ch:8080/SCG/520) and I am planning to use SIXX to store my large tree-structures to xml. It seems to me the perfect solution, because it can handle circular references and it dialect independent. My first attempt was to dump everything out into a XML file using the following code from your tutorial: sws := SixxWriteStream newFileNamed: 'root.xml'. sws nextPut: wikiRootNode. sws close. The XML file looks fine, but unfortunately the XML parser is not able to read that file again. The problem seems to be the huge binary data (images, pdf) that is stored within ByteArray's. I think storing binary-data to XML is not a good idea anyway, so I want them to be put in special external files. The only thing to change - at least I think so - is my Resource class, that contains this binary data. So it should only dump the filename of the binary data and not the data itself. To archive this goal, I wrote something similar to: Resource>>sixxContentOn: aStream indent: level context: dictionary | filename | filename := self generateUniqueFilename. self dumpToBinaryFile: filename. super sixxContentOn: aStream ident: level context: dictionary But how do I prevent SIXX from saving the binary data again, without hardcoding the other i-vars? How do I archive the loading of the binary data? Could you give me some hints? Thanks a lot for your help Lukas -- Lukas Renggli http://renggli.freezope.org
