Subject: [xquery-talk] Group starting with in XQuery?
Message-ID: <3fe5d2bfa5b7631fd1856beaa2ecc8c4@mail.gmail.com>

Just wondering, is there an elegant way of doing something like this in
XQuery?

    <xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
		<xsl:output indent="yes"/>
		<xsl:strip-space elements="*"/>

		<xsl:template match="@*|node()">
			<xsl:copy>
				<xsl:apply-templates select="@*|node()"/>
			</xsl:copy>
		</xsl:template>

		<xsl:template match="P">
			<xsl:variable name="P" select="."/>
			<xsl:for-each-group select="node()"
group-starting-with="pg">
				<xsl:apply-templates select="self::pg"/>
				<xsl:element name="{node-name($P)}">
					<xsl:apply-templates
select="$P/@*|current-group()[not(self::pg)]"/>
				</xsl:element>
			</xsl:for-each-group>
		</xsl:template>

    </xsl:stylesheet>

Example input:

<Docs>
    <Doc>
        <P>blah blah blah<pg>1</pg>blah blah</P>
        <P>blah blah blah<pg>2</pg>blah blah</P>
    </Doc>
    <Doc>
        <P>blah blah blah<pg>3</pg>blah blah</P>
        <P>blah blah blah<pg>4</pg>blah blah</P>
    </Doc>
</Docs>

If you're asking about XQuery 1.0, the answer is no, unless you regard the solution using recursion as elegant.

In XQuery 3.0 there are "tumbling windows" which give you the capability of XSLT's group-starting-with, and a lot more besides.

Subject: [xquery-talk] map module for XQUERY ?

The following libraries are written in pure XQuery 3.0:

rbtree.xq - https://github.com/jpcs/rbtree.xq

Functional implementation of a red/black tree (ordered set) that allows 
a custom implementation of the comparison function. See the included 
"map.xq" for how this can be used to implement a map data structure 
using "lt" comparison. Should be easy to implement an alternative map 
that allows node keys with a suitable comparison function.

hamt.xq - https://github.com/jpcs/hamt.xq

Functional implementation of a hash array mapped trie (hash set) that 
allows a custom hash function and equality function. See the included 
"hashmap.xq" for how this can be used to implement a map data structure.

Hope that helps,

John

I'd be interested in adding sample uses to the github repository if you 
wanted to donate one when you have something working.

Thnx Michael,

Found a tumbling example, and fiddled until I had this:

xquery version "3.0";

let $xml :=
    <Docs>
        <Doc>
            <P>blah blah blah<pg>1</pg>blah blah</P>
            <P>blah blah blah<pg>2</pg>blah blah</P>
        </Doc>
        <Doc>
            <P>blah blah blah<pg>3</pg>blah blah</P>
            <P>blah blah blah<pg>4</pg>blah blah</P>
        </Doc>
    </Docs>
return
    <Docs>{
        for $doc in $xml/Doc
        return
            <Doc>{
                for $P in $doc/P
                return
                    for tumbling window $w in $P/node()
                    start when true()
                    end next $e
                        when $e instance of element(pg)
                    return (
                        $w[self::pg],
                        <P>{
                            $w[not(self::pg)]
                        }</P>
                    )
            }</Doc>
    }</Docs>

Tested with http://try.zorba.io .. :)

Implenting keys($map) can be done using the fold() function. I recall 
the remove() algorithm being a fair amount harder to implement in a 
functional red/black tree, and I didn't need it so I didn't tackle it.

Very happy to accept contributions of a remove() implementation if you 
do it. :-)

This conversation should probably move to personal email or the github 
issue tracker. This isn't a bug, it's by design. If it didn't work this 
way you'd never be able to replace a key that already existed in a map.

David, I researched these options a year or so ago and concluded it was 
time to learn git/github; however lack of good support for hosting large 
binaries kind of forces you to host those elsewhere. Google code seems 
like the other main option.  I wonder if there isn't a possibility SF 
will right the ship, though?

About git: you can use git more-or-less like svn, although there are 
definitely extra steps.  One thing I have come to really like about it 
is the ability to commit changes without immediately sharing them with 
the world (you commit, and then push, as two steps). You could do this 
with svn branches, kind of, but they seem so heavyweight and I never 
really use them as much as perhaps I should. I do find myself searching 
stackoverflow every so often when I get into weird git situations.

+1 for Github.  It's definitely got a learning curve, but there are
lots of resources out there for folks coming from an SVN world.  But
ultimately whatever works best for you.  Just saw Mike's response and
wanted to add that Github does allow you to package up releases for
easy download: https://github.com/blog/1547-release-your-software

Hi David,

I have been upset by the decline of SourceForge for several years now.
Even before this installer junk, it seemed to me that each consecutive
website re-design that they forced on us was worse and slower than the
previous. The final straw for me was that their new Subversion web
browser interface (after they asked everyone to move their svn repo's)
is now sooo slow it's basically broken!

In eXist we made the decision to move to GitHub. It was not easy and
there was a learning curve for those new to Git, but the collaborative
coding mentality of GitHub is awesome. Also Git itself is just years
ahead of SVN and I cannot imagine going back now. As a bonus, we now
also receive pull-requests for fixes from people we have never heard
of, presumably because its so simple to do that. I really think GitHub
is the best game in town and has been for some time.

We had a pig of a time moving from SourceForge (we have been there for
longer than I can remember), we originally used their CSV before they
had SVN. However, after going through the pain, if you want to do it,
I can make your life easier by explaining how we migrated from
SourceForge to GitHub without loosing any revision history.

Cheers Adam.

Github's pretty good - I used this to become familiar with Git (your 
life will get better ;-)):

http://ftp.newartisans.com/pub/git.from.bottom.up.pdf

The main issue I have is it's lack of release management support. And 
yes, unlike HTML 5 I do believe having release checkpoints benefits 
users. :-)

With a dig at HTML 5, I think this thread is now back on topic, right?

Actually I like that GitHub just expects 'tags' and 'milestones'
because this is all that you need to integrate with your release
management tools. I think here the 'less if more' approach is
brilliant. We use several systems together for our release management
but ultimately its all Maven at the root.

I like github, but its git (or generically distributed source control) that
I like

articles like this

http://thehackernews.com/2013/11/github-accounts-compromised-in-massive.html

have me researching the path Eric van der
Vlist<http://eric.van-der-vlist.com/blog/> has
charted

http://eric.van-der-vlist.com/blog/2013/11/06/from-trac-to-gitlab/

with gitlab ... so far my experience mirrors his and I can setup the
security as well (or bad) as I like.

Message-ID: <52939C12.1010800@safaribooksonline.com>

It occurred to me folks on this list might be interested in an article I 
wrote a couple of weeks ago, but may not have seen it.

http://blog.safariflow.com/2013/11/11/the-making-of-lux-xml-query-for-lucene/

Aside from some technical details, it talks a little more broadly about 
XML's relevance and our experience implementing sites both with 
extensive XML tooling, and without.

I expect brickbats - let them fly!

There's also a related presentation (and video should be forthcoming) 
from a talk I gave at the Lucene Dublin conference here:

The near-universal answer is "github".

Probably. It seems to be winning out as the replacement.

The GIMP image editor recently moved away from sourceforge for the
Microsoft Windows port download, because too many people were
downloading malware or clicking on ads that said Download. The response
has been very positive.

We've got a foot in both camps, with Saxon-HE hosted at SourceForge and Saxon-CE at github. We've never used SF for collaborative development, and we've moved our issue tracking and forums to a redmine site hosted at plan.io, so SF is really there now only as a download site and for preserving history, purposes which it seems to handle perfectly well -- given that we don't choose to go down the "unwanted malware" route (which they certainly haven't tried to encourage or bribe us to do as the post alleges).

We of course develop Saxon-HE as a subset of a commercial code base, so the change management issues are rather different; our master source is on a Subversion system that we host ourselves. We tried a few years ago to move to Mercurial (hg) and failed; we've now got sufficient experience of both hg and git that we would probably succeed if we tried again, but there isn't enough incentive to change for its own sake.

Someone tweeted a few weeks ago that we should move off SF because it wasn't cool any more. I responded that coolth wasn't one of our project objectives, and were there any genuine technical reasons? Perhaps now we're hearing one.

How would you retrieve an item from a map if the key was a function? If
functions don't have identity how would you ensure keys were unique?

For a node you could maybe use generate-id() as a surrogate.
