Hi,
Take a look at this blog post:
http://blogs.msdn.com/b/ericwhite/archive/2008/07/10/how-to-create-hierarchy-from-flat-data-using-linq.aspx
It does exactly what you are wanting to accomplish.
One point - if you want to get the text of those headings exactly, including the numbering, then you will want to make use of ListItemRetriever, which returns the list item (i.e. 1.1.1.1) for any given paragraph that is part of a numbered or bulleted list.

Use LINQ to extract the data from a file...

Hi,
I have created a Subprocedure CreateEventList
which populates an EventsComboBox
with a current day's events (if any).
I need to store the events in a generic List communityEvents
which is a collection of
communityEvent
objects. This List needs to be created and assigned to the instance variable
communityEvents.
This method should call helper method ExtractData
which will use LINQ to extract the data from my file.
The specified day is the date selected on the calendar control. This method will be called from the CreateEventList.
This method should clear all data from List communityEvents.
A LINQ
query that creates CommunityEvent
objects should select the events scheduled for selected
day from the file. The selected events should be added to List
communityEvents.
See code below.
Thanks,
public class CommunityEvent
private int day;
public int Day
get
return day;
set
day = value;
private string time;
public string Time
get
return time;
set
time = value;
private decimal price;
public decimal Price
get
return price;
set
price = value;
private string name;
public string Name
get
return name;
set
name = value;
private string description;
public string Description
get
return description;
set
description = value;
private void eventComboBox_SelectedIndexChanged(object sender, EventArgs e)
if (eventComboBox.SelectedIndex == 0)
descriptionTextBox.Text = "2.30PM. Price 12.50. Take part in creating various types of Arts & Crafts at this fair.";
if (eventComboBox.SelectedIndex == 1)
descriptionTextBox.Text = "4.30PM. Price 00.00. Take part in cleaning the local Park.";
if (eventComboBox.SelectedIndex == 2)
descriptionTextBox.Text = "1.30PM. Price 10.00. Take part in selling goods.";
if (eventComboBox.SelectedIndex == 3)
descriptionTextBox.Text = "12.30PM. Price 10.00. Take part in a game of rounders in the local Park.";
if (eventComboBox.SelectedIndex == 4)
descriptionTextBox.Text = "11.30PM. Price 15.00. Take part in an Egg & Spoon Race in the local Park";
if (eventComboBox.SelectedIndex == 5)
descriptionTextBox.Text = "No Events today.";

Any help here would be great.
Look, you have to make the file a XML file type -- Somefilename.xml.
http://www.xmlfiles.com/xml/xml_intro.asp
You can use NotePad XML to make the XML and save the text file.
http://support.microsoft.com/kb/296560
Or you can just use Notepad (standard), if you know the basics of how to create XML, which is just text data that can created and saved in a text file, which, represents data.
http://www.codeproject.com/Tips/522456/Reading-XML-using-LINQ
You can do a (select new CommunityEvent) just like the example is doing a
select new FileToWatch and load the XML data into the CommunityEvent properties.
So you need to learn how to make a manual XML textfile with XML data in it, and you need to learn how to use LINQ to read the XML. Linq is not going to work against some flat text file you created. There are plenty of examples out on Bing and Google
on how to use Linq-2-XML.
http://en.wikipedia.org/wiki/Language_Integrated_Query
<copied>
LINQ extends the language by the addition of query
expressions, which are akin to
SQL statements, and can be used to conveniently extract and process data from
arrays, enumerable
classes, XML documents,
relational databases, and third-party data sources. Other uses, which utilize query expressions as a general framework for readably composing arbitrary computations, include the construction of event handlers<sup class="reference" id="cite_ref-reactive_2-0">[2]</sup>
or
monadic parsers.<sup class="reference" id="cite_ref-parscomb_3-0">[3]</sup>

Hi, extract data from xml file and insert into another exiting xml file

RandomAccessFile? If you know where you want to insert it.Are you sure about this? If using this, the receiving file would have to have bytes inserted that exactly match the number of bytes replaced. I'm thinking that you'll likely have to stream through the second XML with a SAX parser and copy information (or insert new information) as you stream with an XML writer of some sort.

If the files are small, you can load the target file in a DOM document, insert the data from the source file and persist the DOM.
If the files are large, you probably want to use a StAX or SAX.

Extracting data from XML

Im fairly new to XML & web services so bear with me please.
Im trying to extract data from XML documents where the structure/element names are unknown.
The condition for extracting data is if keyword matches some data content.
Im using Java and the DOM API with xcerces and I've managed to parse the XML file, what I need to do next is to traverse the data content checking against keywords and if a keyword matches then to strip the tags and save the data locally ?
Ive trawled through all the documentaion but as theres so many different methods Im somewhat unsuare which is the best way to proceed.
thanks

tough question, i would suggest looking at jdom as solution for you, because it is a relatively simple one to use for searching through a dom. aside from that, its probably up to you what sort of logic you want to use.

Extracting data from xml spreadsheet for JSP

Hi,
Currently i am developing a web application where user can upload a MS excel file, then the application will extract data needed and store into database. But facing problems where those excel files may content massive images that make the file size too large to be upload on to the web. Now i try to export those excel files into xml spreadsheet, to get only text data. Need helps on how to extract data from xml spreadsheet. Which API needed?
Thanks

Without getting into too much detail, a DTD defines the elements that can appear in an xml file, the order they can appear in, which elements can be nested within which other elements, what each element can contain, etc, etc. In short, a DTD defines the structure of the xml file and Microsoft defined a DTD for the xml files that are output by Excel.
This is not taken from an xml file produced by Excel but DTDs look a llittle like this very basic example.
<!DOCTYPE note [
<!ELEMENT note (to,from,heading,body)>
<!ELEMENT to      (#PCDATA)>
<!ELEMENT from    (#PCDATA)>
<!ELEMENT heading (#PCDATA)>
<!ELEMENT body    (#PCDATA)>
]>If you open the one produced for you by Excel in Wordpad or another simple text editor, you may see something like this in there.
However, if you are going to use a parser to access the file for you do not worry about getting to grips with DTDs for a short, simple project.

Extract data from XML file to Oracle database

Dear All
Please let me know, how to extract data from XML file to Oracle database which includes texts & images.
Thanking You
Regards Lakmal Marasinghe

I would do it from the database, but then again, I am a database / PL/SQL guy.
IMHO the database will deliver you with more options. I don't know about "speed" between the two.

How to extract data from xml field to dropdown list?

Hi,
I have designed a form and connected to a SQL server database using a web service. The XML data retrieved from wsdl connection is currently hold in a text field called 'XMLfield'. I need to extract the data such as 'PersonnelName' from XMLfield into a dropdown list. I used the following code and I do not get any error, but nothing come up and all my fields in the forms become bank when i click the dropdown list.
I would appreciate it if anyone can help me with this issue.
form1.DropDownList::click - (JavaScript, client)
xfa.datasets.data.loadXML(form1.XMLfield.rawValue,0,1);
form1.XMLfield.rawValue = xfa.datasets.data.saveXML();
var dataGroup = xfa.resolveNode("xfa.data.Timesheet.Personnel.PersonnelName");
var dataGroupLength = dataGroup.nodes.length;
if (dataGroupLength == 0) {
xfa.host.messageBox("There are no parts in the XML doc");
else {
for (var i=0; i < dataGroupLength; i++){
this.addItem(dataGroup.nodes.item(i).nodes.item(0).value);
Thanks,
Roya

Hi Roya,
I think the loadXML will override your form data, so blanking out your fields. You could try loading the xml data at the xfa.datasets level (that is xfa.datasets.loadXML(form1.XMLfield.rawValue,0,1);) or using E4X to process the XML.
Another option though might be more rework is to use the Acrobat SOAP api which will return you a JavaScript object so you wont have to do any XML work.
There's a good intro to the SOAP api here, http://www.avoka.com/blog/page/11/.

I am using oracle database 10g

Let me explain that the issue is not only related to Oracle.
If you google a bit for default namespace and Xpath you will find many topic.
Basically when you have an XML having a definition of namespace without a prefix:
i.e.:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>Example XHTML document</title>
</head>
<body>
    <p>Sample content</p>
</body>
</html>
this means that all unprefixed elements are belonging to this default namespace.
In this case an Xpath equal to '//title/text()' will not get anything because it is assuming to find the element title within a null namespace. But title in this case is automatically assigned to the default namespace.
When you specify a prefix in a namespace then all elements without prefix are associated to namespace NULL. Using a default namespace is causing a lot of headache.
These links can be giving a clearer picture:
http://www.edankert.com/defaultnamespaces.html
Assuming that you have data like this:
WITH mydata AS
(   SELECT '
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>Example XHTML document</title>
</head>
<body>
    <p>Sample content</p>
</body>
</html>' xmldata FROM DUAL
SELECT xmltype (xmldata).EXTRACT ('//title/text()').getstringval ()
FROM mydata;
This query will not give anything back to you. You will have to specify:
SELECT xmltype (xmldata).EXTRACT ('//title/text()', 'xmlns="http://www.w3.org/1999/xhtml"').getstringval ()
FROM mydata;
Note also that you should be able to get the default namespace when it is specified (without prefix) by using:
SELECT xmltype(xmldata).getnamespace() from mydata;
Post your Oracle version to see if it something related to your version. In mine I got this:

7    <body>
8      <p>Sample content</p>

11 )
12 SELECT xmltype(xmldata).getnamespace() from mydata;
XMLTYPE(XMLDATA).GETNAMESPACE()

If this would work, then it would be enough to add the optional additional parameter namespace. In case it is null it will be set as xmlsn="" and it will work anyway:
Please note that it will work both if the XML has a default namespace or not
i.e.:
with default namespace:

Extracting attributes from XML document using plsql

Hello,
I have successfully written a plsql procedure that has been
using Xpath to extract the element values from an XML doument:
i.e.
l_xpath := '/Form_Data/Person_Details/Initials';
l_DomNodeList := xslprocessor.SelectNodes(l_RootNode, l_xpath);
l_DomNode := xmldom.item(l_DomNodeList,0); -- first Element
l_DomNode := xmldom.getfirstchild(l_DomNode);
l_id_number := xmldom.getNodeValue(l_DomNode);
However the data (Initials) I wish to extract is now stored as
attributes within the Person_Details element and I was wondering
how I would go about explicitly extracting the attributes values!
I have not been able to find any examples, although I have been
pointed in the direction of xmldom.getattribute without any
success!
Any help, or code examples greatly appreciated,
- Mark...

example:-
xpath.VALUEOF(i_doc,v_PricingPath||'@LockIndicator');

Gives result as 1.
But if i run change existNode to extractValue it gives me an error
daying the xpath expression is wrong.
Any ideas?

Hello
Can someone tell me please how to Extract Data from (Financial Reporting in) Hyperion Planning & Budgeting into Excel Using ODI?
Would the steps be the same as Creating an ODI Project and Interface: Exporting a Flat File to a Flat File? If not, why?
Best Regards.

Where do you think the financial reports get their data from? Financial Reports pull data from data sources such as Essbase, HFM.
