Hi,

I have a series of expressions like this (shortened from verbose xml)
=====================
[<text:sequence text:ref-name="refAutoNr0">1</text:sequence>
[<text:sequence text:ref-name="refAutoNr1">2</text:sequence>
[<text:sequence text:ref-name="refAutoNr2">3</text:sequence>
[<text:sequence text:ref-name="refAutoNr3">4</text:sequence>
=====================

I want to globally replace each such line with just

====================
\head
====================

followed by a line space so I get

====================
\head

\head

\head

\head
====================

etc.

I am modifying a script with lines like

====================
data.gsub!(/.*?<(office:text).*?>(.*?)<\/\1>.*/mois) do
'\starttext' + "\n" + $2 + "\n" + '\stoptext'
====================

and don't yet know enough to completely understand. Probably a few more
hours/days of study will get me there but I need this urgently so...

THNX in advance

Best
Idris

Regexps and XML always tend to blow up for me. The pattern you're
searching for seems to be a complete element, why not use <insert XML
parser of choice> and XPath?

With REXML, it should be something like:

document.elements.each('//text:sequence') {|sequence|
sequence.replace_with(REXML::Text.new("\\head\n", true))}

Substitute the XPath expression with one of desired precision. I'm a
little unsure around how REXML treats namespaces in XPath and such, but
if you know what prefix will be used in the document, that should work ou=
t.

The script might also require a little more massaging if you're
outputting to plaintext, but treating XML like, well, XML might get the
heavy lifting of searching for patterns in it done faster if you use a
pattern language operating on the DOM structure directly.

Ok, here are 4 bibliography entries. I just did a follow-up posting

you may prefer to respond to that one. Thank you very much for your

Thank you, David, for your pointers. I'm still very much a novice (at
the level of Chris Pine's Learn to Program) so I could not follow them
all, but I do hope to learn more fast. I just sent a follow-up with
more detail, including the script I'm trying to modify; I hope you have
a chance to look at it...

Thank you again
