Re: String replacement in Cocoon
Ah, I see. If you're using XSP and assigning the strings to variables, the escaping is taken care of automatically for you: I didn't know that. That would work if I had only a single insert statemment, but unfortunately, I'm looping over a collection of nodes in an xml document and generating an insert for each node of the collection. With this approach, it seems I'd have to write the java to extract the collection and then loop, generating an esql insert statement for each. It feels ad hoc even if I could make it work quickly. For right now, rather than generating SQL where special characters have to be escaped, I've decided to use cocoon to generate a text file where the characters do not need to be escaped and then use SQLLDR to load the data. I believe my previous problem was my failure to recognize an XSP page can only be a generator. In order to do what I want, I actually need to write a transformer, which I'll learn to do later when I have a little more time.

Ah, ouch. One thought does occur to me: would it be worth storing the XML in an XML db like XIndice instead? It would save the XML-Text conversion step, and you'd be able to use XPath to pull text back out. I believe my previous problem was my failure to recognize an XSP page can only be a generator.

String replacement in Cocoon
I'm trying to replace something like
SQLStatement
INSERT INTO MyTable(text)
VALUES (' What's the matter?')
/SQLStatement
with
SQLStatement
INSERT INTO MyTable(text)
VALUES ('\ What''s the matter\?')
/SQLStatement
where internal 's are replaced by '' and ? and are escaped by a
backslash. I know how to do this using regular expressions, so if I could
assign the value of //SQLStatement into a java variable in an XSP page, I'd
be OK.
I'd like to take the contents of the first SQLStatement and pipe it into
an XSP page (while preserving whitespace) but can't figure out how to do
that. Is this the right approach, or is there another way?
P.S. I've read Jeni Tennison's string replacement method at
http://www.dpawson.co.uk/xsl/sect2/StringReplace.html#d7016e13
but this won't quite do it as I need to use back references

You probably don't really want to do this ... the database should hold the
proper value of the text, not a value modified for display (or
whatever).

Not sure what you're trying to achieve here. Why do you need the \
escaping?

Re: String replacement in Cocoon
I really do need to do this, as I'm generating insert statements for the
database. My information comes in the form of XML documents which I'm
partially pulling apart to enter in the database. Unfortunately, I can't
just take the information between the tags and generate an insert statement,
because the characters '? have special meaning and have to be escaped.
