So.. I was pestering Paolo via email about help with reading small XML
files and parsing them.. Below are his suggestions -- mind you the
files to
be parsed are WELL under 1Kb if it matters.
You can create a FilePath object (you will actually get a File) using
#asFile.
So, something like this should work:
content := 'foo.xml' asFile contents.
parser := XML.XMLParser new.
parser validate: false.
parser processDocumentString: content
I don't have the source at hand, but it's better if you avoid reading
the whole contents and instead use a Stream. It should be something
like this:
stream := 'foo.xml' asFile readStream.
parser := XML.XMLParser new.
parser validate: false.
parser processDocumentStream: stream
I've been able to verify that I can do this without issue:
stream := './path-to/foo.xml' asFile readStream.
Transcript show: stream.
but when I add the last few lines and have this code snippet it fails :
stream := './path-to/foo.xml' asFile readStream.
parser := XML.XMLParser new.
parser validate: false.
parser processDocumentStream: stream.
Recompiling classes...
Recompiling class: XML.Attribute
Recompiling selector: #key
Recompiling selector: #value
Recompiling selector: #value:
Recompiling selector: #printOn:
Recompiling selector: #printCanonicalOn:
Recompiling selector: #simpleDescription

Recompiling selector: #isLike:
Recompiling selector: #tag:
Recompiling selector: #tag

Recompiling selector: #name:value:
Recompiling class: XML.Attribute class
Recompiling selector: #name:value:
Object: XMLParser new "" error: did not understand
#processDocumentStream:
MessageNotUnderstood(Exception)>>signal (ExcHandling.st:254)
XML.XMLParser(Object)>>doesNotUnderstand: #processDocumentStream:
(SysExcept.st:1436)
UndefinedObject>>executeStatements
(../../../eps_fltinfra/sdfhelper.st:37)
So, I did a quick search through the XML package (~/packages/xml/...)
for
processDocumentStream but found nothing..
Am I missing something? If someone could point me in the right
direction,
that would be great..
