Hi friends. It's been a while.

I working on a project that parses multiples XML and image files. The first
XML (initial data file, idf.xml) contains a serie of nodes, for example:
example of idf.xml
<data><file_name>"data.xml"</file_name></data>
<prefs><file_name>"preferences.xml"</file_name></prefs>
....
I use a sequential preloadnetthing with every node founded in idf.xml, for
each file I use streamstatus to track downloading progress. What I want is to
track the progress of the entire package (data.xml + preferences.xml). That is,
to know the filesize of every xml before the first call of streamstatus.

One aproach is to store the filesize of each file in the idf.xml as:

<data><file_name>"data.xml"</file_name><file_size>27676</file_size></data>

So when I parse the file I know the data.xml + preferences.xml file size and
use it as a 100% value.
I don?t like this solution, It works, but I don' t like it.

There is another way to achieve that?, I would appreciate any sugestions.

Best Regards.

Can you use streamSize?

(And do the filenames really need quotes around them?)

I Can't test it now. But I think I can't, when I preloadnetthing with a XML I
have no cast member to access to its streamsize prop.

Do I need to import it in a cast member as "link to external file" and then
preload it?. This can be done, however, there are image files that changes in
filenames and number, so I have the problem again.

Thanks for the reply, the problem is that I didn?t explain what do the program
do with the files.

For XMLs:

Preload
Use it (populate a proplist)
forget it

For Images:
preload it
create a new #bitmap cast member
import the image to the member with importFileInto
Create a new 3d texture with the member.
don' t forget it until program closes.

The xml is the simplest case, in fact I can put the filesize in the firs XML
(initial data file), But the image files are more complex ( or tedious)

For the double quotes, I made a maxcript XML scene exporter that gave me
problems with some file names. I think It was the & character. So I enclosed
file names with quotes as a fast solution. Maybe I must define a DTD for the
XML (well, another story for that).
