Thanks Laurens,
Where do I execute xdmp:save? It doesn't appear to work with the cq. Do
I need to execute it from a DOS prompt? So far, I have only used the
GUIs to work with MarkLogic.

Greetings,
Would anyone be so kind as to inform me how I might export XML content
from Marklogic to an XML file? If possible, I would like to export all
of the content to XML files.
Thanks.

Hi Gerald,
I have used xdmp:save for that purpose. For a small database you can
iterate
over all your files but eventually your query will timeout. In my case I
just split the collection in a few batches.
I would be interested in a pattern to run this type of query as a
sequence
of transactions.
Maybe someone else can comment on that?
Best regards,
Laurens van den Oever

Hi,
I've recently used xqsync to back up some 500K small files on a dev
machine and to restore them on the test server.
while the dump of the files caused no problems, trying to import them
gave a number of intermittent "non-fatal" errors (see
http://pastebin.com/m263dba50 for more) like this:
WARNING: error in input package E:\data-000.zip
Aug 6, 2009 4:43:00 PM com.marklogic.ps.SimpleLogger logException
SEVERE: non-fatal
java.util.concurrent.ExecutionException:
com.marklogic.ps.xqsync.SyncException:
com.marklogic.xcc.exceptions.XQueryException: SVC-MEMALLOC: Memory
allocation error: VirtualAlloc 134217728 bytes: Not enough storage is
available to process this command.
the commandline I used to import the files is this one (based on
Michael Blakeley's very useful tutorial):
java -cp "xqsync.jar;xcc.jar;xstream-1.3.1.jar;xpp3-1.1.4.jar"
-Xmx1024m -DTHREADS=20 -Dfile.encoding=UTF-8
-DOUTPUT_CONNECTION_STRING=xcc://admin:xxxx@10.101.4.118:8088
-DINPUT_PACKAGE=E: com.marklogic.ps.xqsync.XQSync
following the xqsync readme file, I chose a generous heapsize of 1Gb
for 500K documents and increased the number of concurrent threads as
the docs are small, about 1Kb in size.
a big chunk of the error messages in context can be seen here:
http://pastebin.com/m263dba50
what I'd like to know is whether these errors mean that some documents
have not been imported, and what would the best strategy to make sure
all documents are imported correctly?
cheers,
Jakob.

Hi,
I have an xml like follows and my database contains just one document
with similar tags.
<Root>
<title>cook1
<Category count ="1" >wine and beer, wine and water </category
<Category count ="2" >this is a sample document </category>
</title>
<title>cook2
<Category count ="1" >party and cocktail</category>
<2title>
<title>cook3
<Category count ="1" >wine</category>
</title>
</root>
I would like to use "search: search" function and get following the
string term "wine". .
1. Total number of the matches found in number of <title> tags.
In this example, although the "wine" appears twice in the <title>
"Cook1", it should be counted as 1 and it should return only two
search:result nodes. I set <max-matches> to 1 control this.
But I need to find out how many such matches exist in entire
document. Is there way to find this out without traversing through the
entire search:result ?
2. Along with the search:snippet I always want to display the value
of the <title> tag inside with search:result along with search:snippet.
How can I do this ?
Thank you,
--Joshil
