== XML ==
Remember that CouchDB uses JSON for documents. I think you have three options
here:
1. Convert XML to a JSON document
Instead of storing the XML you mentioned you could maybe transform your XML
into JSON (not always easy, as attributes and subelements can clash, the other
way around is easier):
----
{
"type": "note",
"to": "Tove",
"from": "Jani",
"heading": "Reminder",
"body": "Don't forget me this weekend!"
}
----
2. Store the XML as a string field
I believe this is what you were trying to do. Surround the XML with quotes and
escape any quotes in the XML. I believe most XML libraries have a function to
output XML as a string with all escaping done automatically.
{
"XML":
"<note><to>Tove</to><from>Jani</from><heading>Reminder</heading><body>Don't
forget me this weekend!</body></note>"
}
3. Store the XML as an attachment
You can store arbitrary files as attachments to CouchDB documents.
I'd go route 1, as that will allow you to make use of CouchDB's indexing
features, etc. If you just want to store the data, all three options will work.
== curl >=7.18 and RHEL/CentOS ==
About the curl >=7.18 dependency, I don't know why 7.18 exactly, but I'm sure
the dependency version hasn't been changed for no reason. People have built
CouchDB 0.11 on RHEL/CentOS 5, but yes, you'll need to install a separate curl
>=7.18 build. You could just install curl from source. Or you could package
curl >= 7.18 for installation in a location where it doesn't clash with the OS
curl package and build CouchDB to find curl >=7.18 there, or maybe include curl
>=7.18 in the CouchDB package itself and make it a selfcontained package. It's
not impossible, it's just more work than when you're able to use the vendor's
curl package.

Onderwerp: Problems inserting XML document into CouchDB 0.10.2 on CentOS 5.4
Hello CouchDB experts,
I am using CouchDB at the moment for a potential large scale implementation. I
am faced with the problem that I can't
insert a simple XML document into my CouchDB via the Futon interface.
The CouchDB is version 0.10.2 installed on CentOS. The error message that I get
on the UI is that the data I insert is not
a string.
The document I try to insert looks like this:
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>
If I mask the the data with "" I can insert the data, but since I plan to
insert XML documents I can have "" everywhere.
At the moment this is a show stopper and I wonder if there is a special way or
procedure on how to store XML data within CouchDB.
The second question I have is, why is CouchDB 0.11 depended on curl 7.18? This
fact makes building the new CouchDB version impossible
without breaking a lot of things within the CentOS (RHEL 5). Has anyone
eventually produced a how to for CentOS on how to build CouchDB 0.11
for CentOS?
Thanks in advance,
Ralf Himmelein
