Original xml from child nodes

I need to be able to get a String with the original xml for all the child nodes once I traverse a DOM tree and find a particular node.

Use the method suggested above, but unless you've done it before it might not be obvious how to get it into a string.
Here's the trick:
// Create a StringWriter
StringWriter sw = new StringWriter();
// Wrap the StringWriter with a PrintWriter
PrintWriter pw = new PrintWriter(sw);
// Print the node, passing the printwriter
yourNode.print(pw);
// Retrieve the string result from the underlying stringwriter
String theXMLText = sw.toString();

XML file - Child Nodes Array

Just starting to learn about XML.
I have a simple XML file that I created which is as follows
<?xml version="1.0" encoding="utf-8" ?>
<Probes>
<Probe>
<Location>Ambient</Location>
</Probe>
<Probe>
<Location>panel1</Location>
</Probe>
<Probe>
<Location>panel2</Location>
</Probe>
<Probe>
<Location>panel3</Location>
</Probe>
</Probes>
Using XML Property Node - Child Nodes Array results in an array of 9 elements:
#text
Probe
#text
Probe
#text
Probe
#text
Probe
#text
My question is what are all the #text that are there? Shouldn't the child nodes be just the probes?
Solved!
Go to Solution.

It sounds to me like you may be heading down a dark path. Instead of using the 'Child Nodes Array' and fighting through the complications like extraneous text nodes, let me suggest you look into XPath and use 'Get All Matched Nodes.vi' or 'Get First Matched Node.vi' to get the elements. XPath makes parsing XML a breeze.
For Example:
Of course I hope that using XP does not mean you are using LV8.6 or earlier since the XPath VIs are new to LV9.
If you are using LV8.6 or earlier I suggest looking into the .NET functions to implement XPath. Once you get the hang of it, it still beats trying to parse XML the old fashioned way.
As to the editor, I generate very few XML files by hand, mostly I get them from other programs and parse them in LV. Again, XPath smooths out the rough edges.

Table with DropDownBox with data from child node

Hi,
I have following context:
Node Parent (0..n)
-- Node Child (0..n)
Child Attribute 1
Child Attribute 2
-- Parent Attribute 1
-- Parent Attribute 2
The parent node has a child node with cardinality 0..n. Now I created a table from the Parent node with several columns. In one column is a
DropDownBox that should display the data of the Child node, depending on the Parent node element.
Parent | Parent DropDownBox |
Parent 1 | Parent 1 Child Attribute 1 |
Parent 1 Child Attribute 2
Parent 2 | Parent 2 Child Attribute 1 |
Parent 2 Child Attribute 2
How can I fill the child node with data depending on the parent node element? How is the mapping between both?
IParentElement parentElement;
IChildElement childElement;
while (rs.next()) {
 parentElement = wdContext.createParentElement();
 parentElement.setAttribute1(rs.getLong("ID"));
 parentElement.setAttribute2(rs.getString("SYSTEM"));
 wdContext.nodeParent().addElement(parentElement);
 while (rs2.next()){
 childElement = wdContext.createChildElement();
 childElement.setAttribute1(rs2.getLong("ID"));
 childElement.setAttribute2(rs2.getString("NAME"));
 wdContext.nodeChild().addElement(childElement);
If the child node is non-singleton I have the following option
parentElement.nodeChild.addElement(childElement);
But this doesn't work for singleton nodes. How can I do something similar for singleton nodes?
Thanks for your help,
Andi

Not quite correct.
You can add more than one element to a singleton node (if cardinality is *:N).
But a singleton child node exists only once per parent node and not once per parent element.
That's an important difference.

Abap mapping - get_value from child node

Hi experts,
I'm doing an abap mapping, but i have some problems extracting data from XML message.
I have:
child = element->get_first_child( ).
while not child is initial.
       wa_reg-registro = child->get_value( ).
       insert ZTABLE from wa_reg.
      child = child->get_next( ).
endwhile
I can see in my table ZTABLE the expected result, but consecutive blanks are all replaced by exactly one space character .
Why?
How can I solve this problem?
Thanks

Any imput, please

Update xml column by inserting any missing child nodes from a M_V

Hello all,
I am trying to update a xml column(col1) of a table (abc) by looping through, by selecting from a materialized view and find any missing (child) nodes in the existing table (abc) of a xml column (col1) on each rows, and then do update the xml column (col1) of table (abc). How to do this in Oracle pl/sql?.
Thanks & Regards,
Josh

You do not need stored procedure for that. Use something like APPENDCHILDXML, INSERTCHILDXML or INSERTXMLBEFORE. For example, to insert a node into XML document:
SELECT APPENDCHILDXML(
 XMLTYPE(
 CURSOR(
 SELECT ENAME,
 SAL
 FROM EMP
 WHERE DEPTNO = 10
 '//ROW',
 XMLTYPE('<ROW><ENAME>user631757</ENAME><SAL>10000</SAL></ROW>')
 ) EMP_XML
FROM DUAL
EMP_XML
<?xml version="1.0"?><ROWSET><ROW><ENAME>CLARK</ENAME><SAL>2450</SAL><ROW><ENAME
user631757</ENAME><SAL>10000</SAL></ROW></ROW><ROW><ENAME>KING</ENAME><SAL>5000</SAL><ROW><ENAME>user631757</ENAME><SAL>10000</SAL></ROW></ROW><ROW><ENAME>MILL
ER</ENAME><SAL>1300</SAL><ROW><ENAME>user631757</ENAME><SAL>10000</SAL></ROW></R
OW></ROWSET>
SELECT INSERTXMLBEFORE(
 XMLTYPE(
 CURSOR(
 SELECT ENAME,
 SAL
 FROM EMP
 WHERE DEPTNO = 10
 '//ROW[ENAME="KING"]',
 XMLTYPE('<ROW><ENAME>user631757</ENAME><SAL>10000</SAL></ROW>')
 ) EMP_XML
FROM DUAL
EMP_XML
<?xml version="1.0"?><ROWSET><ROW><ENAME>CLARK</ENAME><SAL>2450</SAL></ROW><ROW>

Need to chart attribute value of just one child node of XML document

I have a XML document with (for example) 7 parent nodes, each
parent node has 5 child nodes. The parent nodes have an attribute
@EarlierDTS (DateTime type) that is the x-axis category of a chart.
Each child node has an attribute @eventid which specifies the id of
the event, and another atttribute @NumOccurs which specifies how
many times that event occured in that period.
How do I tell Flex I want a simple line chart of the eventID
= 215? What if I want two lines, for both eventID=215 and
eventid=307?
I have studied the posts and blogs for over a week now, and
have seen this question or similar come up quite a few places, with
no answer.
1) Should I focus on learning how to create a filterfunction
for the XMLList that underlies my XMLListCollection so that the
filtered data view is just one child node per parent node ( or two
child nodes for the second case)? And set the filtered data view as
the dataprovider of my chart's vertical series?
2) Should I focus on learning how to create a XML Filter
query that selects just one or two child nodes for each parent
node, and set the charts' series' dataprovider to this filter
expression? (I don't think this is allowed - but I'm checking with
the forum members...)
3) Should I focus on learning how to convert the
XMLListCollection into a HierarchicalData object, and then learning
how to filter this object so there is only one (or two) childs per
parent? This seems like a lot of coding - I almost have to create a
pair of classes - one for the parent and one for the child - so I
can create nested ArrayObjects.
4) Should I create a brand new XMLList by walking the
original XML list, and inserting Parent nodes and just the child
nodes that match the eventID(s) I want to chart, into the new
XMLList?
I believe that the easiest way would be to create a
Filterfunction for the XMLList, and bind the chart series to the
(filtered) XML List. But the problem with this approach is that I
have seen more than 2 posts asking how to accomplish filtering that
removes specific children from the view, with no solutions posted.
Help! What is the best way to get just one child for each
parent, from an XMLList?

I'd just look at a dataFunction. There's an example here that
may point you
in the right direction:

Is it possible to restrict the user from creating a sibling and allow him to ONLY create child nodes in DRM?

When in a hierarchy, a user right clicks on a node to crate a new node, he has two options
-Child
-Sibling
Is it possible to restrict the user from creating a sibling and allow him to ONLY create child nodes?
Business cases:
1. different level nodes need to have different prefixes.
- Thus, the default prefix property definition uses the level number to assign a prefix
- Also, a validation, to ensure the correct prefix, uses the level number
But if the user can create a child and a sibling then the default prefix will only be right for a single case and not both.
Thanks

Oracle SQL - Extracting clob value from XML with repeating nodes

Hi All,
I am attempting to run SQL on a table (called test_xml with a column xml_data [data type xmltype]). The column contains xml with repeating nodes (description). The following statement runs successfully when the node contains data of a non clob size:
SELECT
extractvalue (Value (wl), '*/description')
FROM test_xml
, TABLE (xmlsequence (extract (xml_data, '*/record'))) wl
but fails when description node contains a lot of data:
ORA-01706: user function result value was too large
I amended my query:
SELECT
extractvalue(Value (wl), '*/description').getClobVal()
FROM test_xml
, TABLE (xmlsequence (extract (xml_data, '*/record'))) wl
but this fails with:
ORA-22806: not an object or REF
Thanks in Advance

Hi Greg,
11.2.0.2.0 (Although I will need to do this on my work instance also which is 10.2.0.4)That's gonna be a problem...
Direct CLOB projection is supported starting with 11.2.0.2, using XMLTable or XMLCast/XQuery functions (extractvalue, extract, xmlsequence are deprecated now) :
SELECT x.*
FROM test_xml t
   , XMLTable(
       '/*/record'
       passing t.xml_data
       columns
         description clob path 'description'
     ) x
;On prior versions, implicit conversions will occur to VARCHAR2 datatype, hence the limitation observed.
AFAIK you have two options on 10.2.0.4 :
1) Using Object-Relational storage, with the xdb:SQLType="CLOB" annotation.
2) Using the following trick :
SELECT dbms_xmlgen.convert(x.description.getClobVal(), 1) as description
FROM test_xml t
   , XMLTable(
       '/*/record'
       passing t.xml_data
       columns
         description xmltype path 'description/text()'
     ) x
;

Create root node and child nodes while downloading data from internal table

Hi all,
i have to down load the details of three materials present in the internal table into
a XML file, the material number must be the root node, ERNAM,AENAM,VPSTA
fields must be its child nodes. in this way i have to display details of three
materials like material1,material2,material3.
how can i do that in 4.6c version.
Thanks,
satish.

Hi Satish,
Please look into the following programs. These are sample SAP programs to deal with XML in 46c.
BCCIIXMLT1
BCCIIXMLT2
BCCIIXMLT3
Hope these will helps,

How to append an xml string as a child node to a dom document

Hi
I have an xml represented as a String. Now I want to add this xml string as a child node to another DOM Document.
Do I have to first parse the xml String into a xml Document and then add the nodes to the existing Document. Is there a simpler way to do this. Any input is appreciated.
Many thanks in advance.

Xpath: get attributes from first child node

Hi,
I have some problems by getting the attributes from the first child node, if i try to get child elements everything works fine, but whenever i need the elementvalue from a node with attributes i doesn't return anything.
The xpath expression works fine if i want to get the element value from all childs, but not when i just want from one of them.
This one works,
XPathFactory factory1 = XPathFactory.newInstance();
 XPath xpath = factory1.newXPath();
 xpath.setNamespaceContext(new PersonalNamespaceContext());
 XPathExpression expr
 = xpath.compile("//default:DeviceExchange[1]/default:Status/text()");
 // gets the value of the node picked out
 Object result = expr.evaluate(doc, XPathConstants.NODESET);
 NodeList nodes = (NodeList) result;
 for (int i = 0; i < nodes.getLength(); i++) {
 names[i] = nodes.item(i).getNodeValue();
 String a = names;
// checks if status is exchanged, if it is sets status to 1
if (a.length() == 9){
names[i] = "1"; }
else{ names[i] = "0";}
System.out.println(names[i]);This doesn'tXPathFactory factory2 = XPathFactory.newInstance();
XPath xpath2 = factory2.newXPath();
xpath2.setNamespaceContext(new PersonalNamespaceContext());
XPathExpression expr2 = xpath2.compile("//default:DeviceExchange[1]/default:Field[@names='MLPKTID']/text()");
Object result2 = expr2.evaluate(doc, XPathConstants.NODESET);
NodeList nodes2 = (NodeList) result2;
for (int i = 0; i < nodes2.getLength(); i++) {
names2[i] = nodes2.item(i).getNodeValue();
System.out.println(names2[i]);}Does anyone have any ideas? I will apreciate all help!

How can I remove child node from JTree???

I use the model : DefaultMutableTreeNode
Thanks

There are a couple of ways it can be done. If your tree uses DefaultTreeModel as its TreeModel, you can use removeNodeFromParent(). This will remove the node from its parent and effectively remove its children, too. All nodes removed will be garbage-collected if there are no other references to them.
If your tree model is not the default tree model, but still uses MutableTreeNode, you can use either remove() or removeFromParent() on the node itself, depending on whether you want to remove the node itself or one of its children.
On the other hand, your tree may use a model that simply "mirrors" another data structure, in which case you would have to remove the node from the other data structure and have it reflected in the model.
