How to start learning XPATH and XQUERY

Hello
Please I am needing some guide to know if there is a guide that I could follow so that I can handle from the very beginning till the end an XML Document.
Besides I need to know if with JDeveloper I can edit and update an XML document (data type XMLTYPE column) inside of a table.
I'll appreciate your help.
Paola.
@}--->----->>----------

You could have a start here http://www.w3schools.com/. also the old XMLDB manuals 9.2, 10.1 had primers on handling xml (appendix section), another source for you could be the w3c organization: http://www.w3.org/.
AFAIK, JDeveloper doesn't have that functionality yet. AFAIK the latest toad version is able to do this...

  • XSLT, XPath and XQuery

    Hi,
    1.Can you differentiate these XSLT, XPath and XQuery.
    2.How Do I Force a Rollback in a BPEL Flow.
    Thanks in advance

    XQuery is to XML what SQL is to database tables. XQuery was designed to query XML data.
    XPath is used to navigate through elements and attributes in an XML document. XPath is a major element in W3C's XSLT standard - and XQuery and XPointer are both built on XPath expressions.

  • How to start learning OAF

    Hi,
    I'm very new to OA Framework, and I have read through most of the threads in this forum and skimmed through the development guide, but I still have a few questions.
    1) Where can I download Jdeveloper 10g with OA externsions? It seems Jdeveloper can be downloaded from Metalink, but I don't know how to sign up for it. Can I download Jdeveloper 10g with OA externsions without having Metalink access?
    2) Is a database required to learn and develop OAF components? One of the steps for setting up Jdeveloper obtain a dbc file. I don't know were to obtain a dbc file nor do I have a database to work with.

    Thanks,
    HusseinHi Hussein,
    Thanks for the quick response. Unfortunately, I don't have a CSI number or a DBA to turn to. I'm a college student, and I'm not working for an IT company. Hence I lack a lot of resources. I made this thread to see if I am wasting my time learning OAF because I can't acquire the necessary resources (db and jdeveloper).

  • How to start learning about Oracle identity mgmt

    Hi All,
    I want to learn OID, Can any one suggest from where to start learning this topic and practising it.
    Thnaking You,
    Rakesh.

    It seems a good approach, although I think SSO can be learned independently (although it can use an LDAP dir to store credentials, it can be done without learning much about it).
    In all the IdM world, I think the basic start point is to learn about LDAP. And as OIM has not a ldap backend like other provisioning solutions, you will interact a lot with directories. This is the first step I always ask for people who starts working with me. SSL/TLS and certs should be studied later, gaining a complete understand of directories world.
    Every Directory differs only in their own admin console, but if you use pure LDAP, all dirs are the same. OID has its things, but with strong LDAP knowledgement, there will be no problem in understand it.
    OIM is the last stand, because it integrates everything. I suggest that first, you try to learn how to use it, as if you were an administrator (this can be done if you get some VM with oim preinstalled with at least 2 connectors working). Then, when you get all oim concepts (users, orgs, groups, access policies, process, etc), you can begin with implementing your own stuff, like making your own installation, deploying connectors, extending their functionality, etc.
    OIM has the power of being extended with java code, so after all of it, I recommend as the very final step, to get inside the java world and begun writing your own code, decompiling the connectors code so you can figure how oim works, etc etc

  • How to start learning German?

    I love Arch.  Absolutely love it.  But with the announcement of April 1 regarding the transition to German, I was wondering if there are any books available that will help me learn this fine lanaguage and continue using this excellent distro?
    Hopefully, I would like a German version of  the edutainment game "Reader Rabbit" to begin the basics; preferably open-source, but if I must I'll get wine working if I really have to!
    Thanks, Archers!
    Gute Nacht!

    If you are actually serious about learning German: First of all make sure, that you have an ongoing motivation to learn the language. If that's missing, you'll probably give up frustrated after some weeks, because learning a language can be frustrating.
    Then get yourself a dictionary and a course book with many demonstrative explanations for the grammar. Start by learning the basics: nouns, articles, verbs and the basic sentence structure S-V-O (subject-verb-object). Try to find a German-speaking friend and try to practise your knowledge, even if you can only say simple things like "Ich spreche Deutsch.", "Der Mond ist rund." or a little more complicated: "Heute ist der erste April."
    Also start to read as much as you can. Learning vocabularly is no fun, but it's easier if you remember vocabulary from the context, because you see that a word is important and not only word of many in a vocabulary list.
    Now expand your knowledge slowly by learning more, reading more and practicing your new knowledge as often as possible and try not to get frustrated once you encounter the more challenging parts of the German language.
    Also consider a stay in a German-speaking country once you have basic knowledge. You'll be amazed how fast you learn when you're in contact with native speakers - just don't get frustrated.
    Good luck!
    Funny thing is that I started looking for resources to learn German this morning.
    I studied it at school for 5 years (over 30 years ago) and although I can read German pretty well, albeit with a limited vocabulary, I have never spoken it since.
    My daughter is moving to Bonn in May and I plan to visit her in September / October so I want to have some proficiency by then.
    At the moment I am sure my grammar would be like the Englishman in Allo Allo.
