Hi guys
I have a question about XMLWriter. I have cards and group of cards.
Each class know how to serialize itself.
For card I have xmlOn: (one of my methods) that describes the card attributes
Card>>xmlOn: aWriter
"write a description of the receiver properties as xml uing aWriter, an instance of
XMLWriter"
aWriter tag
name: #card;
with: [self xmlInstVarOn: aWriter]
Group>>xmlOn: aWriter
"write a description of the receiver properties as xml uing aWriter, an instance of
XMLWriter"
| cardWriter |
cardWriter := XMLWriter new.
cards do: [:each | each xmlOn: cardWriter].
aWriter tag
name: #group;
with: [
aWriter tag: #groupName with: self groupName.
aWriter tag: #cards with: [ aWriter raw: cardWriter contents]]
And I'm not really happy. Because I would like to avoid to use raw: and instantiate a
new writer.
I would like to know how I could use the write to pass the results of the iteration over
cards
I wanted to write something like
aWriter tag
name: #group;
with: [
aWriter tag: #groupName with: self groupName.
aWriter tag: #cards with: [self cards do: [:each | each xmlOn: aWriter]]
