Parse XML by using NSXMLDocument
I know how to parse external file or an URL XML, but what if I have a string - NSString that contains XML data, how should I do to let NSXMLDocument prase this string?
thank you.

I don't get your problem either. An element doesn't have a length. Perhaps you need the length of the text of the TextNode that is the only child of your AttributeValue element?

How to parse xml string using JSTL
Suppose this is my string:-----
<books>
<book>
<title id=1>Book Title A</title>
<author>A. B. C.</author>
<price>17.95</price>
</book>
<book>
<title id=2>Book Title B</title>
<author>X. Y. Z.</author>
<price>24.99</price>
</book>
</books>
and I want to read title id = 1 then, how to parse it, I found tutorials regarding parsing simple xml document but how to parse attributes of a given XMLBut both of them either parse a file or data from an input source. I don't think they handle strings.An InputSource can be constructed with a Reader as input. One useful subclass of Reader is StringReader, so you'd use something likeDocument doc = documentBuilder.parse(new InputSource(new StringReader(myXMLString)));

Help Parsing XML Mesage using PeopleCode
Hi all,
I'm new to web services and XML but was able to consume a WSDL and call the web service successfully.
I'm now trying to parse the XML message I’m getting as a response and to extract values i need and having issues Parsing the response. Below is what I have done and the code from my Test AE. Basically I’m trying to navigate to the "Results" element in the response and then use GetChildNode to get child nodes and then use FindNode to find elements and their values.
Here is the WSLD I consumed to create the web service in PS. I only need WSDL operation doSearch_3_15
[https://www.epls.gov/epls/services/EPLSSearchWebService?wsdl ]
My PC below calls the web service and passes last name “ZERMENO” as a search parameter and this should return 3 results back.
I’m grabbing the reply back and parse it to extract the values I need.
+&inXMLDoc = CreateXmlDoc("");+
+&ret = &inXMLDoc.ParseXmlString(&reply.GenXMLString());+
The issue I’m having is being able to get “inside” the results node (there are 3 of them) and loop through the child nodes and get my values.
Code from Test AE:
Local string &payload, &responseStr, &last;
Local Message &msg, &reply;
Local XmlDoc &xml, &inXMLDoc;
Local array of XmlNode &GetElements, &RecordList, &field1List, &aResultsNode;
Local XmlNode &RecordNode, &ClassificationNode;
Local File &MYFILE;
+&FilePath = "/psoft/fin9/fpsdv1/prod/ap/files/";+
+&FileName = "uhc_report.xml";+
+&MYFILE = GetFile(&FilePath | &FileName, "W", %FilePath_Absolute);+
+&payload = "<?xml version='1.0'?> <doSearch xmlns='https://www.epls.gov/epls/services/EPLSSearchWebService'>";+
+&first = "";+
+&last = "ZERMENO";+
+&payload = &payload | "<query><first>" | &first | "</first><last>" | &last | "</last></query> </doSearch>";+
+&xml = CreateXmlDoc(&payload);+
+&msg = CreateMessage(Operation.DOSEARCH_3_15, %IntBroker_Request);+
+&msg.SetXmlDoc(&xml);+
+&reply = %IntBroker.SyncRequest(&msg);+
If All(&reply) Then
If &MYFILE.IsOpen Then
+&MYFILE.WriteString(&reply.GenXMLString());+
Else
MessageBox(0, "", 0, 0, "Can't Open File.");
End-If;
+&inXMLDoc = CreateXmlDoc("");+
+&ret = &inXMLDoc.ParseXmlString(&reply.GenXMLString());+
If &ret Then
+&field1List = &inXMLDoc.GetElementsByTagName("results");+
If &field1List.Len = 0 Then
MessageBox(0, "", 0, 0, "GetElementsByTagName Node not found");
Error ("GetElementsByTagName Node not found");
+/* do error processing */+
Else
For &j = 1 To &field1List.Len
If &j > 1 Then
+MessageBox(0, "", 0, 0, &field1List [&j].NodeName | " = " | &field1List [&j].NodeValue);+
+&RecordNode = &inXMLDoc.DocumentElement.GetChildNode(&j);+
If &RecordNode.IsNull Then
MessageBox(0, "", 0, 0, "GetChildNode not found");
Else
+&ClassificationNode = &RecordNode.FindNode("classification");+
If &ClassificationNode.IsNull Then
MessageBox(0, "", 0, 0, "FindNode not found");
Else
+&SDN_TYPE = Substring(&ClassificationNode.NodeValue, 1, 50);+
MessageBox(0, "", 0, 0, "&SDN_TYPE = " | &SDN_TYPE);
End-If;
End-If;
End-If;
End-For;
End-If;
MessageBox(0, "", 0, 0, &inXMLDoc.DocumentElement.NodeName);
Else
+/* do error processing */+
MessageBox(0, "", 0, 0, "Error. ParseXml");
End-If;
Else
MessageBox(0, "", 0, 0, "Error. No reply");
End-If;
see link below for the XML reply web service message with some Notes. Also link for the response as an XML doc (had to add .txt to the xml extension to be able to upload it). I appreciate your help and feedback.
http://compshack.com/files/XML-Message.png
http://compshack.com/files/uhc_report.xml_.txt
And here is the output from my Test AE. I'm able to find 3 count of results, which i expected since I have 3 records coming back from the web service, but for what ever reason, GetChildNode is failing.
results = (0,0)
GetChildNode not found (0,0)
results = (0,0)
GetChildNode not found (0,0)
results = (0,0)
GetChildNode not found (0,0)

Edited by: Maher on Mar 12, 2012 10:41 AMHi,
I just took a closer look at the code and the looping using childnodes and findnode is not correct a bit overkill.
You should really use the one or the other.
I have created two other loops
Loop 1, loop through all elements using Childnodes:
Local string &payload, &responseStr, &last;
Local Message &msg, &reply;
Local XmlDoc &xml, &inXMLDoc;
Local array of XmlNode &GetElements, &RecordList, &field1List, &aResultsNode;
Local XmlNode &RecordNode, &ClassificationNode;
Local File &MYFILE;
&inXMLDoc = CreateXmlDoc("");
&ret = &inXMLDoc.ParseXmlFromURL("c:\temp\test.xml");
If &ret Then
&field1List = &inXMLDoc.GetElementsByTagName("results");
If &field1List.Len = 0 Then
MessageBox(0, "", 0, 0, "GetElementsByTagName Node NOT found");
Error ("GetElementsByTagName Node NOT found"); /* do error processing */
Else
For &j = 1 To &field1List.Len
If &j > 1 Then
MessageBox(0, "", 0, 0, &field1List [&j].NodeName | " = " | &field1List [&j].NodeValue);
&RecordNode = &field1List [&j];
&RecordChildNode = &RecordNode.GetChildNode(&j);
If &RecordChildNode.IsNull Then
MessageBox(0, "", 0, 0, "GetChildNode NOT found");
Else
MessageBox(0, "", 0, 0, "&RecordChildNode name:" | &RecordChildNode.NodeName);
If &RecordChildNode.NodeName = "classification" Then
MessageBox(0, "", 0, 0, "NodeName = " | &RecordChildNode.NodeName);
&SDN_TYPE = Substring(&RecordChildNode.NodeValue, 1, 50);
MessageBox(0, "", 0, 0, "&SDN_TYPE = " | &SDN_TYPE);
End-If;
End-If;
End-If;
End-For;
End-If;
MessageBox(0, "", 0, 0, &inXMLDoc.DocumentElement.NodeName);
Else /* do error processing */
MessageBox(0, "", 0, 0, "Error. ParseXml");
End-If;results = (0,0)

Loop 2, look for classification node, using FindNode:

Local XmlDoc &xml, &inXMLDoc;
Local array of XmlNode &GetElements, &RecordList, &field1List, &aResultsNode;

If &j > 1 Then
&RecordNode = &field1List [&j];
&ClassificationNode = &RecordNode.FindNode("classification");
If &ClassificationNode.IsNull Then
MessageBox(0, "", 0, 0, "FindNode not found");
Else
&SDN_TYPE = Substring(&ClassificationNode.NodeValue, 1, 50);
MessageBox(0, "", 0, 0, "&SDN_TYPE = " | &SDN_TYPE);
End-If;
End-If;
End-For;
End-If;
MessageBox(0, "", 0, 0, &inXMLDoc.DocumentElement.NodeName);

As you can see, several possible solutions are possible.

I have a xml file NewXML.xml. When I parse it I'm not getting the expected output: I'm trying to get only the value of the "name" tag. When I tried getElementByTagName("name"), I'm not getting the expected result.
Here is my xml file based on a schema

NodeList nodeList1 = nodeList.item(0).getChildNodes();

Importing/Parsing XML using SQL and/or PL/SQL
What is the recomended way of importing/parsing XML data using SQL and/or PL/SQL?
I have an XSD that defines the structure of the file, and an XML file that has the content in the appropriate structure. I have parsed (checked) the structure of the XML file using JDOM in my java application, and then passed it to a function in a package on the database as a CLOB.
What I need to do is parse the contents of the XML file that is passed into the function and extract the values of each XML element so that I can then do some appropriate validation before inserting and committing the data to the database (hence completing the import function).
A DBA colleague of mine has been experimenting with various ways of acheiving this, but has encountered a number of problems along the way, one of which being that he thinks that it is not possible to parse XML elements that are nested more than four levels deep - is this the case?
The structure of the XSD/XML that the database function needs to manipulate and import data from is very complex (and recursive by it's nature).
I would appreciate any suggestions as to how I can achieve the above in the most efficient manner.
Thanks in advance for your help
DavidThis is the forum for the SQLDeveloper tool. You will get better answers in the SQL and PL/SQL forum, and especially the XML DB forum.
Oracle has comprehensive and varied support for XML, including a PL/SQL parser. -
I am trying to parse XML Schema using XSOM. The Schema has <xs:include>s
e.g. I have first.xsd which includes second.xsd and second.xsd again includes third.xsd.
First.xsd
<xs:include schemaLocation="../Second.xsd">....
Second.xsd
<xs:include schemaLocation="Third.xsd">....
When I parse "First.xsd" parser passes the correct path "C:/XSDSchema/Second.xsd"(First.xsd resides in "C:/XSDSchema/Schema/") to the EntityResolver's resolveEntity method. But for Second.xsd it passes "Third.xsd" only (Third.xsd resides in "C:/XSDSchema/" ) .
Any Idea ?????Here is a screenshort of the part of my workflow:
In the mappings of the "Set Value" activity, I have one line with those properties:
Location: /process_data/bonusValidationForm/object/data/xdp/datasets/data/BonusValidationForm/buMan agerID
Expression: /process_data/currentUser/object/@userId
Where:
bonusValidationForm is a process variable of my workflow that point my xdp form
buManagerID is the textfield I want to set
currentUser is a process variable (type User) that was well setted by the task Find BU Manager -
i wrote java client to invoke webservice(TIBCO) as a result i am getting back xml. now i have to parse xml and use the information. can anyone pls advise on this.
thanksThere are two kinds of parser available. One converts the XML to a Document Object Model (DOM). This is a heirarchy of Node objects each of which represents an element of XML, a tag, an attribute a piece of text etc.. Then you walk the graph extracting what you want.
The other kind is the SAX event parser. You give this a callback (extends DefaultHandler) and it calls appropriate methods for each element as it's encountered.
The second method is probably slight more complex to use but will deal with files of unlimited size without huge memory usage.
In both cases you get the parser using a Factory/Interface pattern. You'll find the factory classes in javax.xml.parsers. The rest of the DOM stuff is in org.w3c.dom and the SAX stuff in org.xml.sax. -

Parsing an xml file using xerces DOM parser
Hi
I want to parse a simple xml file using DOM parser.
The file is
<Item>
<SubItem>
<title>SubItem0</title>
<attr1>0</attr1>
<attr2>0</attr2>
<attr3>0</attr3>
</SubItem>
<SubItem>
<title>SubItem1</title>
<attr1>1</attr1>
<attr2>0</attr2>
<attr3>0</attr3>
</SubItem>
<SubItem>
<title>SubItem2</title>
<attr1>1</attr1>
<attr2>1</attr2>
<attr3>0</attr3>
<SubItem>
<title>SubItem20</title>
<attr1>2</attr1>
<attr2>1</attr2>
<attr3>0</attr3>
</SubItem>
<SubItem>
<title>SubItem21</title>
<attr1>1</attr1>
<attr2>1</attr2>
<attr3>0</attr3>
</SubItem>
</SubItem>
</Item>
I just want to parse this file and want to store the values in desired datastructures,
I am trying using DOM parser, since it gives a tree structure, which is ok in this case.
public void init()
InputReader ir =new InputReader("Habsys");
Document doc =ir.read("Habitat");
System.out.println(doc);
traverse(doc);
private void traverse(Document idoc)
NodeList lchildren=idoc.getElementsByTagName("SubItem");
for(int i=0;i<lchildren.getLength();i++)
String lgstr=lchildren.item(i).getNodeName();
if(lgstr.equals("SubItem"))
traverse(lchildren.item(i));
private void traverse (Node node) {
int type = node.getNodeType();
if (type == Node.ELEMENT_NODE)
System.out.println ("Name :"+node.getNodeName());
if(!node.hasChildNodes())
System.out.println ("Value :"+node.getNodeValue());
NodeList children = node.getChildNodes();
if (children != null) {
for (int i=0; i< children.getLength(); i++)
traverse (children.item(i));
But I am not getting required results, a lot of values I am getting as null
Could anybody tell me how to retrieve the data from the xml file, I simply want to read data and store it in data structures. For eg, for tag Subitem with title as ' SubItem1' has attr1 as '1', attr2 as'0' and attr3 as '0'.
Thanks

Can't parse xml from applet using dom on linux on Netscape 7 using jre 1.4.
Hi,
I can't seem to parse xml from an applet on linux on Netscape 7 using the JRE 1.4.
My code looks like the following:
StringBufferInputStream is = new StringBufferInputStream("<foo></foo>");
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
try
builder = factory.newDocumentBuilder();
domDocument = builder.parse(is); // this line creates an exception
catch (Exception e)
System.out.println(e);
This code works fine from an applet on windows. On linux, the error message is:
java.security.AccessControlException: access denied (java.util.PropertyPermission entityExpansionLimit read)
I've tried both JRE 1.4.0_04 and 1.4.1_03
Thanks!
QThere's another posting about this same problem (platform unspecified), but the same error message. I was also having this problem (Windows 1.4.03) and swithced back to 1.4.01 and the problem went away. In the future, I may sign my applets to get a more generous security policy. But, I'm sure it'll be a lot of work (vs. a line of code somewhere).

Problem in parsing a xml string using dom parser
i want to parse a Xml String using a Dom parser......the parse function in dom parser takes only input stream as argument.......so i made the code as
InputStream inputstream = new StringBufferInputStream(XmlData) ;
InputSource inputSource = new InputSource(inputstream );
but saxexception is coming and also warning called
"java.io.StringBufferInputStream in java.io has been deprecated"
please help me.........i want to parse a Xml String using a Dom
parser......the parse function in dom parser takes
only input stream as argument.......This is not true of the DOM parser in Java 1.4. So you might want to get rid of your old parser and replace it by something more current. Or perhaps you are using 1.4 and you just didn't read all of the API docs. -
Problem parsing xml in J2ME (using kxml2)
Hello.
May someone who knows how to use kxml help me please?
I'll try to be straight forward. (Please excuse my imperfect English)
My xml file look something like this:
<?xml version="1.0" encoding="utf-8"?>
<sample_tag1 xmlns:mysample="http://www.sample001.com/sample01schema">
<feature name=tag1_feature>
<test name=xxxxx id=200 message=Hello.></test>
</feature>
<catalog name="shelf">
<booklist name="book1" label="b1"></booklist>
<booklist name="book2" label="b2"></booklist>
<booklist name="book3" label="b3"></booklist>
</catalog>
</sample_tag1>
And here's my code
//http request
try{
//I can guarantee that the URL is valid
httpConnection = (HttpConnection) Connector.open(URL);
}catch(IOException ioe){
ioe.printStackTrace();
//Create the parser
KXmlParser parser = new KXmlParser();
try{
//I use this code section to test if the xml file is properly placed in the inputStream.
char[] tempChar = new char[500];
isr = new InputStreamReader(httpConnection.openInputStream());
isr.read(tempChar);
for(int i=0; i<tempChar.length;i++){
System.out.print(tempChar);
//set the xml input
parser.setInput(isr);
//skip the "<?xml version="1.0" encoding="utf-8"?>" tag
parser.nextTag();
parser.require(XmlPullParser.START_TAG, null, "sample_tag1");
System.out.println("name : " + parser.getName());
System.out.println("namespace : " + parser.getNamespace());
parser.nextTag(); // ***1
I compiled the app and run, here's the result:
name : sample_tag1
namespace :
org.xmlpull.v1.XmlPullParserException: attr value delimiter missing! (position:START_TAG <feature name='http://www.sample001.com/sample01schema'>@3:15 in java.io.InputStreamReader@e938beb1)

My code is the clone of the one in this tutorial:
http://www.developer.com/ws/article.php/3759471
where he get the weather forecast from Yahoo Weather RSS
What did I do wrong? I tried looking up google for "attr value delimiter missing!" but found no useful information.
Thank you in advance. =)Please read this topic. I posted an answer about parsing xml using kxml2
