XmlDocument and XPath should work.
XPath doesn't handle an anonymous namespace, so you'll have to give the namespace a name using a NamespaceManager for this namespace:
xmlns="http://schemas.microsoft.com/VisualStudio/TeamTest/UITest/2010"
lets say you choose the name 'x' for this namespace. (Any name will do.)
Then use some xpath like this: Beware your typo!
//x:UIObject[@Id='UIEnterpirseIDEdit']
(The typo above is your own -- I cut and pasted it. Also, ID vs Id is case sensitive)
The whole thing might look like this:
(This time I've fixed the typo so that it finds an actual node in your example xml)
XmlDocument doc = new XmlDocument();
doc.Load( "XmlFile1.xml" ); // or however you want to load your XML.
XmlNamespaceManager nsmgr = new XmlNamespaceManager( doc.NameTable );
nsmgr.AddNamespace( "x", "http://schemas.microsoft.com/VisualStudio/TeamTest/UITest/2010" );
XmlNode node = doc.SelectSingleNode( @"//x:UIObject[@Id='UIEnterpriseIdEdit']", nsmgr );
Console.WriteLine( node.OuterXml ); // Example to demonstrate that it works.
Again, be aware that the example node Id you wanted to find has a typo in it.

How to parse nested xml file using dom

i want to parse nested xml file
please tell me how to parse nested xml
for eg.
<xml>
<row>
<name>Rahul<name>
<row><newXml>
<newXML>
<Row>
<code>12</code>
</Row>
<newXML>
<XML>
please tell how to parse this file

Normally if you have no idea about X, the first thing you should do is google "X tutorial". You will find plenty of them out there. And the advantage is, they are better written than whatever we spend two minutes throwing together here. Not to mention that it saves us the two minutes.
But if you have specific questions with your SAX parser when you get it going, then ask them here. Actually, ask them in the XML forum here, not this one.

Which is the best way to parse nested XML

Hello, I am just getting back into using ColdFusion and I am
working on a project that needs to parse some XML.
The XML is generated by a third party document.
I figured out how to grab individual values and such, but I'm
not sure what is the best way to grab a value in relation to where
it is in the XML.
Following is a rather simplified example of the XML
I need to grab the value of 'Rich Text' in relation to the
'ID name' value.
<project>
<CT text>
<Group>
<id name = text1>
<Rich Text>some sample text</Rich
Text>
</id>
</Group>
</CT Text>
<CT text>
<Group>
<Group>
<id name = text1>
<Rich Text>some sample text</Rich
Text>
</id>
</Group>
</Group>
</CT Text>
<CT text>
<id name = text2>
<Rich Text>some more sample text</Rich
Text>
</id>
</CT Text>
</project>
Once parsed, the info I need to output on the page would look
like
text 1
some sample text
text 2
some more sample text
The part that makes this difficult for me is that there may
be 0 'Group' values or there might be a number of them. As such, I
can't just grab the value by listing the tree out, since it changes
depending on the document (there are thousands of these documents
that I need to parse).
From what I have seen in some XML examples, there are a
number of ways to go about doing this, but before I put a lot of
time into any of them, I was wondering what the 'best' way to do
this is.
XSLT? XMLSearch? Structures? Some combination of those or
other functions?
P.S. what little I know of using ColdFusion with XML all
comes from the doc written by Nate Weiss.
I was a bit let down that after spending well over $1,000 for
ColdFusion, Adobe left out the only two books that were worth
printing (the CFML reference guide and the Advanced book). It
wouldn't have bothered me as much if there was something on the
product page listing the manuals that said 'we only actually give
you 2 of the ones listed'.
Best regards
Kevin R.

Hello,
Could someone do me a huge favor and provide some sample code
that would parse/output the above xml so that the output would look
something like the following. . .
text 1 = some sample text
text 2 = some more sample text
The problem I am having is displaying the xmltext for the
RICH TEXT element in relation to the ID element.
The code below will return the value of the RICHTEXT
(incorrectly named in the original XML examples) easily enough, but
I need to have it show which text number it is.
Best regards,
Kevin R.

How to construct the where clause for a nested xml target file

Post Author: jlpete72
CA Forum: Data Integration
I'm having some problems getting the desired results creating a multi-level nested xml file. Specifically, it does not seem that the where clause in the child schemas respects values from parent schemas. I'm sure I'm constructing something incorrectly, but am running out of ideas.
I am working with the classic company/order/line hierarchy and there are three levels of output schemas in my target xml file, one for company, order header and order line information.
For testing, I have hardcoded a restriction at the order header line to deal with only one order. But unless I hardcode values into the where clause at the order line level of the schema, all values are returned for orders belonging to the company defined in the company level.
I'm trying a where clause at the order line level similar to:
order_line.customer = order_header.customer and order_line.order_num = order_header.order_num
If the customer has more than one order in the data file, then all orders for that customer are placed in the detail for the order header. Only if I hard code the order number in the where clause do I get only the lines for the order specified in the header section. Not very practical.
What am I missing?

An External Parsed Entity could be used to reference a schema.
In your DTD:
<!ENTITY datamodules SYSTEM "file:///c:/Datamodules/Datamodules.xsd">
Refer the external entity in xml document:
<datamodules>&datamodules;</datamodules>

Parsing a XML using Jdom --- Problem pls help

Hi all,
I am reposting it as I was told to format the code and send it again.
I am trying to parse a xml file using a jdom java code.This code works fine if I remove xmlns attribute in the root element. (I get the expected result) .If the "xmlns" attribute is put in the xml as it should be then the parsing and retrieving returns null. Please tell me how to fix this issue.

Your elements have a namespace (the default one) so it should be worth a try.

               </return>
          </ns3:commandResponse>
     </env:Body>
</env:Envelope>This is just a sample with just one WorkItem, but there would be much more, N number of items with 9 fields per item. (Not all of the fields were put in the sample, and some can have null values)
I only need to pull the content from /ns2:WorkItems/ns2:Field/ns2:Value/ns2:Item/ns2:Id for the first field and the /ns2:value/* tag of all the other fields. Then put this in a table where each row is a workitem and the fields are the columns (create table workitems (Type,ID,Reason,Dev Task Component,Created Date, Date Closed, Modified Date) --all the fields should be varchar2 except the dates)
What I've been trying so far seems rather brute force by running a nested loop to go through every item and field and then an IF case for each field 1,2,...9 which would insert the value into a table.
At the moment I'm using something like below to pull a single value
path1 = '//ns2:WorkItems[1]/ns2:Field[1]/ns2:Value[1]/ns2:Item[1]/ns2:Id[1]';
nameserve = 'xmlns:ns2="http://test.com/2011/Generic/schema"';
extractvalue(xmltype(src_clob),path1,nameserve);I'm not entirely sure if I would be able to substitute the [1]'s with [' || nitem || '] where nitem is loop number to do something like:
for nitem in 1..itemcount
loop
    FOR nfield in 1..9
    loop
        if nfield=1 then
            path1 := '//ns2:WorkItems[' || nitem || ']/ns2:Field[' || nfield || ']/ns2:Value[1]/ns2:Item[1]/ns2:Id';
            fieldvalue := extractvalue(xmltype(src_clob),path1,nameserve);';
        else
            path2 := '//ns2:WorkItems[' || nitem || ']/ns2:Field[' || nfield || ']/ns2:Value[1]/*[1]';
            fieldvalue := extractvalue(xmltype(src_clob),path2,nameserve);';
        end if;
    end loop;
end loop;The problem with the above script is how do I insert this fieldvalue into different columns on a table without using an IF case for each field.
I was wondering if there is simpler way to put each field into a different column and loop through every workitem. I looked into dynamically naming variables but I don't think plsql supports that.
Any help/advice is appreciated,
Thanks!

If it were me, I wouldn't use PL/SQL to try and process XML, but would use SQL's XMLTABLE functionality e.g.

Parse complex XML in PL/SQL

have complex XML with depth level 10. I need to parse and store data into tables from XML. I am able to parse simple XML but not complex. Could any body suggest me the required steps to parse complex XML in PL/SQL?

Spry Menu Using Nested XML Dataset (Spry 1.6)

I have a vertical menu with a few items. One of which is
labeled Products which has submenus. I want to have that submenu
read from a Nested XML dataset. Using a single dataset for one
level in a menu is easy enough, but the subenu will have submenus.
Example Menu:
Home
Company
Products
|-- Product 1
|-- Item 1
|-- Item 2
|-- Item 3
|-- Product 2
|-- Item 1
|-- Item 2
|-- Product 3
|-- Item 1
|-- Item 2
|-- Item 3
|-- Item 4
|-- Product 4
|-- Item 1
|-- Item 2
|-- Product 5
I have been looking for an easy way to use the Spry Nested
XML Dataset to create the Product/Item menu. The number of Products
may vary as well as the number of Items in each Product submenu
(also, some Products may not have Items).
I already have an ASP page that creates the XML data from a
database.
Schema follows (XSD ):
<?xml version="1.0" encoding="utf-8"?>
<xsd:schema xmlns:xsd="
http://www.w3.org/2001/XMLSchema">
<xsd:element name="products">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="product_type"
maxOccurs="unbounded">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="type_name" maxOccurs="1"
type="xsd:string"/>
<xsd:element name="type_url" maxOccurs="1"
type="xsd:anyURI"/>
<xsd:element name="product_name"
maxOccurs="unbounded">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="item_name" maxOccurs="1"
type="xsd:string"/>
<xsd:element name="item_url" maxOccurs="1"
type="xsd:anyURI"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
I have been programming for 17 years but am new to Spry. If
this cannot be done easily with the Spry framework, I'll probably
wind up splitting the XML data into 2 files (Products and Items)
then writing a nested loop and call each by row, but then I have to
find out how Spry Datasets reference XML data. Figuring out how to
call rows from the XML data shouldn't be so bad, but this method
just seems like such a hassle for something that should be easy.
Pseudocode follows:
j=1
i=1 to TotalNumberProducts
display Product i from Products
ItemsExist=true
While ItemsExist
if j > TotalNumberItems | Item j is not for Product then
ItemsExist=false
else
display Item j from Items
j++
Wend
Next
Thanks in advance for any help or direction!

That's exactly what I'm trying to do. However, I implemented
that code and the submenus won't appear. I suspect the submenus
aren't finding the field names from the Nested XML Dataset. The
first level of Product menus work great (this is a submenu of the
overall menu) and correctly identify products that do not have
submenus, so I know it's picking up the number of records in the
Nested Dataset correctly - it just won't display the data in the
next level of menu.

"Error while parsing SOAP XML payload: no element found" received when invoking Web Service

Running PB 12.1 Build 7000. Using Easysoap. Error ""Error while parsing SOAP XML payload: no element found" received when invoking Web Service". This error does not appear to be coming from the application code. Noticed that there were some erroneous characters showing up within the header portion of the XML ("&Quot;"). Not sure where these are coming from. When I do a find within the PB code for """" it gets located within two objects, whereas they both reference a "temp_xml_letter". Not sure where or what temp_xml_letter resides???   The developer of this is no longer with us and my exposure to WSDL and Web Services is rather limited. Need to get this resolved...please.
This is the result of the search. Notice the extraneous characters ("""):

Maybe "extraneous" is an incorrect term. Apparantly, based upon the writeup within Wiki, the parser I am using does not interpret the """? How do I find which parser is being utilized and how to control it?
<<<
If the document is read by an XML parser that does not or cannot read external entities, then only the five built-in XML character entities (see above) can safely be used, although other entities may be used if they are declared in the internal DTD subset.

Unable to display tree view; Error when parsing an XML document (Premature end of file.)

Hi folks,
I am using a cascaded mapping in my OM. I have a graphical mapping followed by the Java mapping. It is a flat file to IDOC mapping. Everything works fine in Dev but when I transport the same objects to QA, the Operation mapping though it doesn't fail in ESR testing tool, gives the following message and there is no output generated for the same payload which is successfully tested in DEV. Please advise on what could be the possible reasons.
Unable to display tree view; Error when parsing an XML document (Premature end of file.)

kalyan,
There seems to be an invalid xml payload which causes this error in ESR not generating the tree view. Please find the similar error screenshot and rectify the payload.

Parsing an xml document inside a Thread

Hi Friends
I have to do some processing in my application for which i need to use multithreading.
Inside every new thread created i have to parse an xml document using s parsing tool like castor or jibx.
My question is that is it possible to parse a xml document inside a new thread everytime it gets created.
is it a good coding practice as it involves java code to do it.
Thanks
Vikeng

Hi
Thanks for the reply.
Well i need to do some kind of a batch processing in my application.
I need to parse an xml document and upload the data i get after parsing into columns in the database.
Since its a batch what i was asking was is it possible to do it for every request as batch needs to handle hundreds of records during the daily or nightly sync.
Is it a good practice to do parsing for every record in a batch
Thanks
VikengI don't get it. One batch is one document, and that document contains e.g. 100 records? What's one request? A request for one batch? I would execute one batch in one thread.
