Re: Special Parsing Using XML-INTO

Jon,

I've looked at it, I understand what it's giving you...

I realize it doesn't give you a string you can just concat into a buffer.

But couldn't you _rebuild_ the input XML string one piece at a time from
the information provided?

when event = *XML_START_ELEMENT;
buffer += '<' + %subst(chars : 1 : stringLen);
when event = *XML_END_ELEMENT;
buffer += '</' + %subst(chars : 1 : stringLen) + '>';

Non trivial for sure. And you probably couldn't get an exact copy of the
input XML. But the result should certainly parse the same..

Rather XML-INTO would be easier or not would depend on the structure of the
XML you are trying to extract I think.

You’ll have to look at XML-SAX Charles.

You _cannot_ do what you are suggesting with XML-SAX because what XML_SAX
passes its handler is: A code to indicate the type of data (basically
beginning of a specific attribute or element name, end of same, etc.), the
actual name of the item found or the data for the element/attribute. As you
can see - there is no way there to get the XML string - it has already been
parsed out into its components.

Doesn’t help.

XML-SAX will break out the components (element name and element data)

just

the same as XML-INTO does. Only difference is it does it one field at a
time. Not helpful for the OP.

I can think of a risky non-guaranteed strategy where XML-SAX might help

-

but it relies on the compiler internals remaining consistent and I
certainly wouldn’t want to base production code on it - a one-time

routine

maybe.

​Jon,

I'll admit to not having used XML-SAX...

However, it would seem to me that it'd be easier to build a string
containing a subset of the XML from within the XML-SAX handler.

At least then you don't have to worry about the structure of the subset
data.

Though the handler might be a bit complex...since you'd have to rebuild

the

string one event / data at a time.
