Build the delta from two xml documents

Hi,
i look for a solution to solve the following problem:
i want to build a xml-based interface to pass my data to a client(Web etc.) and i dont know in which way the client manipulates the data and what in the xml-document was changed, inserted or deleted.
What i have is the original-document and the changed-document (both based on the same DTD). How can i determine the delta from the two documents, cause i must know what actions to be taken (for example put <?bc4j remove?> or an appropriate tag for the XDK in the xml)
any suggestion ???
TIA
Oliver

The Oracle XDK for Java comes with a utility called XMLDiffer that, given XML Documents A and B, produces an XSLT stylesheet S that transforms A to B.
Might be of use to you. That's the only inhouse XML diffing technology that I'm aware of. We use it internally in JDeveloper for merging machine-generate web.xml file edits with the user's hand-written web.xml file edits.

How to compare the contents of two XML documents

Hi all,
I was trying to compare the contents of two xml documents, they are both validate for the same XML Schema. i was using the xmlunit to do this. but some how it doesn't work like what i have expected. for example:
1.xml : <test><item>2</item><item>1</item></test>
2.xml: <test><item>3</item><item>2</item><item>1</item></test>
the result from XMLUnit is this two xmls are different, but it compares <item>2</item> with <item>3</item>, which i cannot find out where the real diiffs are.
does anybody know how i can do this correct?
best regards,
tina

I faced a similar problem in one of my projects and hence wrote my own comparator. Most comparators like ExamXML etc show XML as different if the nodes under a parent node occur in different seqeunce or a set of repeated nodes occur in different sequence. The comparator that I wrote gives you the flexibility to configure how to identify a node from a set of repeated nodes and is able to compare them successfully if they occur in any order. You can view the sample output at http://geocities.com/dheerendra_itbhu/TipsFromDheeru.html
and contact me in case you need the source code.

Possible to combine two xml documents into a single query?

In ASP, PHP, etc. if I wanted to combine two tables and
filter by one =
item, I would create a recordset combining the two on one
common element =
and have one recordset. Is that possible with xml documents
and Spry =
datasets?
I have xml information sent to me 4 times a day from a
weather service. =
This happens automatically, but the two xml documents
(current.xml and =
forecast.xml) are set in stone by the service. However, if in
my Spry =
dataset, I could combine them so I could list the 15 cities
in a master =
region and have tabs for the current conditions and forecast
which would =
each access a separate xml document but needs to do that from
the city =
link on the left, that would work great.
Can I do this as I would be able to if I had a database with
different =
tables?
Thanks!
Nancy

Hi Kin:
They are really static xml files that are placed in a folder
directly by =
the weather service. The files in question are current.xml
and =
forecast.xml.
And there is not one per city .. but just one of each. the
location =
node in current.xml and the citycode node in forecast.xml
contain the =
same information.
If I were doing this in a recordset with a database, I would
write =
something like SELECT whatever from current, forecast WHERE =
current.location =3D forecast.citycode AND current.location
=3D variable =
(which would be what is clicked on).
This sets up a master/detail arrangement for the first one
that works =
fine. Click on the city code (which I have to write something
to say If =
location =3D FAT, document.write "Fresno" and so on) and the
rest of the =
current information displays fine on the right side of the
page. Now I =
have to marry that to the forecast.xml file so that when
citycode =3D =
FAT, the five day information for Fresno shows up .. and so
on. I was =
planning to use Spry tabs or whatever to show the data.

How to insert data into a table from an xml document

using the XmlSql Utility, how do I insert data into a table from an xml document, using the sqlplus prompt.
if i use the xmlgen.insertXML(....)
requires a CLOB file, which i dont have, only the xml doc.
Cant i insert directly from the doc to the table?
the xmlgen examples I have seen first convert a table to a CLOB xmlString and then insert it into another table.
Isnt there any other way?

Your question is little perplexing.
If you're using XML SQL Utility from
the commandline, just use putXML.
java OracleXML putXML

The size of a XML document stored in a XMLType table

Is there a way to find out (via SQL) the size of a XML document stored in a XMLType table or XMLType column (storage OR based)?
For instance in the way you could it retrieve if the XML document was stored in an XMLType column (CLOB based)
SQL> r
1 select dbms_lob.getlength(t.gegevens.getclobval()) "SIZE"
2 from hgo.hgo010_detam t
3* where rownum < 2
SIZE

Saving the data from two info path forms in to a single list in share point 2010

Hi ,
I have two info path forms are in share point page FM 1 and FM 2.
In FM 1 I am getting data from lists by using drop down and casket drop down and FM 2 i need to enter manually after entering
i want to save both forms information(FM 1 & FM 2 ) in to a single list of share point 2010
If any knows the solution please reply me
Thanking You,
Arun Darly

Hi，
Based on your description, my understanding is that you want to save the data from two info path forms in to a single list in share point 2010.
We can't save the data from two info path forms in to a single list, but we can
save the data from two info path forms in to a single library.
Open the FM 1 and FM 2 in Infopath(you have save it Locally once).
Publish the FM 1 and FM 2 as content types named FM 1 and FM 2.
Add the content types FM 1 and FM 2 into a document library, Then you can save the data
from two info path forms in to a single library.

Read xml-structure from a xml-document stored in a xmltype-column?

Hello,
I have several xml-documents stored in a table with a xmltype-column.
Is it possible to read the structure of one xml-document? I need to know what data are exists in the xml-documents.
I had read some hours here, but I dont find a suitable solution for that.
To make a example, what I need:
I have stored the following xml-document in the table:
<?xml version = '1.0'?>
<ROWSET>
<ROW num="6">
<EMPLOYEE_ID>105</EMPLOYEE_ID>
<FIRST_NAME>David</FIRST_NAME>
<LAST_NAME>Austin</LAST_NAME>
<EMAIL>DAUSTIN</EMAIL>
<PHONE_NUMBER>590.423.4569</PHONE_NUMBER>
<HIRE_DATE>6/25/1997 0:0:0</HIRE_DATE>
<JOB_ID>IT_PROG</JOB_ID>
<SALARY>4800</SALARY>
<MANAGER_ID>103</MANAGER_ID>
<DEPARTMENT_ID>60</DEPARTMENT_ID>
</ROW>
</ROWSET>
I need to return the following:
ROWSET
...ROW
......EMPLOYEE NUMBER
......FIRST_NAME VARCHAR2
......DEPARTMENT_ID NUMBER

Hi,
I was on a wrong way. The datatype is not stored in xml, this was a mistake from me.
I needed something to printout some values from a xml-file. This xml-file was generated bei MS Excel. The data are in /Workbook/Worksheet/Table/Cell and I didnt know how to access it.
I write for that the following:
DECLARE
v_xml XMLType;
v_doc dbms_xmldom.DOMDocument;
v_node dbms_xmldom.DOMNode;
type t_values is table of varchar2(2000) index by binary_integer;
v_values t_values;
type t_table is table of t_values index by binary_integer;
v_table t_table;
procedure node_output (v_node in out dbms_xmldom.DOMNode)
is
v_nodelist1 DBMS_XMLDOM.DOMNodeList;
v_nodelist2 DBMS_XMLDOM.DOMNodeList;
v_anzahlnodes number;
v_anzahlrows number;
v_node_c dbms_xmldom.DOMNode;
v_xmlmitarbeiterid number;
begin
v_nodelist1 := dbms_xmldom.GETCHILDNODES(v_node);
v_anzahlrows := DBMS_XMLDOM.GETLENGTH(v_nodelist1);
if v_anzahlrows = 0 or DBMS_XMLDOM.GETNODENAME(v_node) = 'Table'
then
if v_anzahlrows > 0
then
for i1 in 0..v_anzahlrows - 1
loop
v_node := dbms_xmldom.Item(v_nodelist1,i1);
v_nodelist2 := dbms_xmldom.GETCHILDNODES(v_node);
v_anzahlnodes := DBMS_XMLDOM.GETLENGTH(v_nodelist2);
for i2 in 0..v_anzahlnodes - 1
loop
v_node := dbms_xmldom.Item(v_nodelist2,i2);
v_node_c := dbms_xmldom.GETFIRSTCHILD(v_node);
v_node_c := dbms_xmldom.GETFIRSTCHILD(v_node_c);
v_values(i2) := DBMS_XMLDOM.GETNODEVALUE(v_node_c);
end loop;
v_table(i1) := v_values;
end loop;
for i1 in 1..v_anzahlrows - 1
loop
select SEQ_XMLMITARBEITER.nextval into v_xmlmitarbeiterid from dual;
for i2 in 1..v_table(i1).count - 1
loop
dbms_output.put_line(v_table(i1)(i2));
end loop;
end loop;
end if;
else
v_node := dbms_xmldom.GETFIRSTCHILD(v_node);
for i in 0..v_anzahlrows - 1
loop
v_node := dbms_xmldom.Item(v_nodelist1,i);
node_output(v_node);
end loop;
end if;
end;
BEGIN
select inhalt into v_xml FROM xmlimport WHERE name = 'F23973/mitarbeiter.xml';
v_doc := dbms_xmldom.newDOMDocument(v_xml);
v_node:= dbms_xmldom.makeNode(dbms_xmldom.getDocumentElement(v_doc));
node_output(v_node);
END;
This gives me all data from a xml-Excel-file. Is there a better way to do that? I have Oracle 10.2.

Difference between two xml documents

Hi,
I have two xml documents docA and docB that loos like this,
<root>
<a>
    <b>...</b>
    <c>...</c>
    <d>...</d>
</a>
<a>
</a>
</root>I want to compare them and get a new xml document that consists of every <a> thats only in docB (I know that the only two cases is that a given <a> is either in both or only in docB) is there any library that can help me with this? I've looked at xmlunit but I could only get it to either just return true/false or give a complete list of differences.
/Andreas

You have not really specified precisely what you want to compare on. XQuery 1.0 and XPath 2.0 have a function deep-equal that might be able to do what you want so an XQuery like
<root>{
doc('docB.xml')/root/a[not(some $a in doc('docA.xml')/root/a satisfies deep-equal(., $a))]
</root>could give you the result you want, depending on whether the [specification of deep-equal|http://www.w3.org/TR/xpath-functions/#func-deep-equal] matches your expectation.
As the SUN Java JRE has no XQuery support you need a third party library such as [Saxon 9|http://saxon.sourceforge.net/] .

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

Hi,
Use NVL or COALESCE:
NVL (col_a, col_b)
Returns col_a if col_a is not NULL; otherwise, it returns col_b.
Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).
