Xerces - Parse XML from String

I am trying to parse an xml string using Xerces.
I have the following code:
String xml = <segments meters="8643" seconds="538" distance="5.4 mi" time="8 mins"><segment id="seg0" pointIndex="0" meters="122" seconds="11" distance="0.1 mi" time="11 secs">Head southwest from B Ave NE

How to Parse XML into String in BPEL?

Hi,
Can anyone tell me, how can I parse XML into String?
I am taking input from File Adapter, File adapter is reading that XML.
Then in assign activity i am using XPath expression(built functions) using XMLParser(),doTranslateToNative() etc.. many functions I have tried but XML is not getting parsed into String Variable.
Please help me asap.
Thanks

Parsing XML from Socket input stream

I create a sax parser to which I send the InputStream from the socket
But my HandlerBase never gets the events. I get startDocument
but that is it, I never get any other event.
The code I have works just like expected when I make the InputStream
come from a file. The only differeence I see is that when I file is used the
InputStream is fully consumed while with the socket the InputStream
is kept open (I MUST KEEP THE SOCKET OPEN ALL THE TIME). If the parser
does not generate the events unless the InputStream is fully consumed,
isn't that against the whole idea of SAX (sax event driven) .
Has anyone been succesfull parsing XML from the InputStream of a socket?
if yes how?
I am using JAXP 1.0.1 but I can upgrade to JAXP 1.1.0
which uses SAX 2.0
Does anybody know if my needs can be met by JAXP 1.1.0?
Thanks

I did the same with client/server model.
I have client program with SAX parser. Please try if you can make the server side. I was be able to write the program with help from this forum. Please search to see if you can get the forum from which I got help for this program.

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!
Q

There'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).

Parse XML from CLOB field

How can I parse XML from CLOB field? I need to replace or delete the node from XML document and update the database with new XML. I am using Oracle 9i release 2.
Here is the XML. In this XML if section1 and section2 exists then I need to delete the section1 node. If section2 doesn't exist, replace section1 with section2 node.
<Document ID='2' TypeID='2'>
<Body>
<Page Name='Page1'>
<Sec ID='section1' Title='Section 1' GroupID='' />
<Sec ID='section2' Title='Section 2' GroupID='' />
</Page>
</Body>
</Document>
Please help.. Thank you..

In 9.2, you are limited into your options. Have a look into, among others, updateXML. Updating tp 10gR2 will give you more options to succeed.

Extracting the xml from string and parse it

Hi all,
I have a webservice, and calling one of the methods, returns xml data but store this data in a string.
For example:
String str = keysstub.getUserLMLArray(UserID,hash, Provider, Filter.ALL,TimeStampString).getXmlResults();returns <id>123456</id><id>123457</id><id>123458</id><id>123459</id><id>123461</id>and stores it in str.
I have to take read this xml from the string and parse it accordingly to retreive the data from it.
Please suggest how i can parse this xml from the string. it will be of great help. Code snippets from anyone would be of great help
Thanks and Regards,
Shikha

Parsing XML from a session bean

Hi,
I am trying to use a Sax parser for parsing xml received from a back end
legacy system. The code is executed from a Session bean.
Debugging learned me that the parse() method on the parser hangs the
container without any error or exception trace. The code works fine outside
a container.
All help will be highly appreciated.
Kurt

I found out that the InputStream implementation used parsing source inside
the container is different
then from the one outside (other type of VM of course!). The Weblogic
implementation blocks at the end of
the stream, while the normal SUN JDK 1.3 returns. This is not a bug, the bug
I found is in my proxy that allows
the connection to the backend. This proxy allows HTTP connections, and I
parse the XML received over HTTP.

Kurt

That's seems odd. Perhaps there is something going on in your document
handler code that triggers a hang in the environment of the server.
When you see the hang, instruct the VM to give you a thread dump (type
control-<break> on Windows, <control>-\ (backslash) on UNIX in the
window in which the server is running; the results are dumped to
stderr). That will show what every thread in the server is doing. If you
email or post the thread dump, I will take a look at it and see if I can
see what is going on. Also, let us know which platform, VM, parser, and
WebLogic version you are using.

How to use DOMParser from an Applet / Or, how to parse XML from an Applet?

Hey,
As stating in the subject line, I wonder how to do it without getting an �Access Denied� error.
I would like to parse a XML file that has external DTD pointing to a SYSTEM location. Yes, I can change it to a public location. However, in either way, I have problems to use DOMBuilder to parse the xml file. The application always throws the security exception.
I tried to use the DOMParser from org.apache.xerces.parsers to parse the xml file. I set the DOMParser to ignore parsing the external DTD, and use the DOMParser.parse(InputSource) to parse the xml file from a giving URL. However, I get null of the result document.
Does anyone know how to parse the XML from an Applet? Or, does anyone know how to use the DOMParser from an Applet?
Thank you very much,

If the document resides on the local filesystem, you will need to sign a CAB or JAR for the applet to circumvent the sandbox's security restrictions. There are dozens of posts on how to do this. Basically, that will turn the applet into an application, from a Java security perspective.

Parsing xml from a socket stream

Hi,
I'm working on a client/server program, and I have the following problem. I'd like the client to send an xml-string to the server, and then the server to parse it (using SAX). The problem is, I cannot get the server to work.
I thought the following would work, but it doesn't:
InputSource xmlIn = new InputSource(socket.getInputStream());
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser xmlReader = factory.newSAXParser();
DefaultHandler handler = new MyHandler(); //
xmlReader.parse(xmlIn, handler);
The setup now is, that the user of the client program can type something in the command line, press enter and the string is then sent to the server, which should parse it, but doesn't (instead gives a nullpointer exc.)
Does anybody know how to parse an incoming string like this?
thnx in advance,
KS

The parser expects to read to the end of the stream. If you closed the stream right after you wrote to it, I bet it would work. You wouldn't want to close the stream though would you? Try sending the string using a DataOuputStream and calling DataOutputStream.writeUTF(String) on the client side. Then, on the server side call String str = in.readUTF() (where 'in' is a DataInputStream). Then wrap the string in a StringReader and give the StringReader to the parser as it's input source.

Parse XML formatted String

Hi All,
 I have a string field that is formatted in XML format. What I want to be able to do is pull a specific element from the xml formatted string.
Example string:
<customer><name>john</name><id>25636</id></customer>
I want to retreive just the id number of 25636 from this string.
I would I go about accomplishing this?
Thank you in advance,

I fixed it on my own.
Here' s my answer for others that may need it:
if(instr({field.xmlstring},'</id>') - instr({field.xmlstring},'<id>') = 7)then
 mid(totext({field.xmlstring}),instr({field.xmlstring},'<id>')+4,3)
else if(instr({field.xmlstring},'</id>') - instr({field.xmlstring},'<id>') = 8)then
 mid(totext({field.xmlstring}),instr({field.xmlstring},'<id>')+4,4)
else if(instr({field.xmlstring},'</id>') - instr({field.xmlstring},'<id>') = 9)then
 mid(totext({field.xmlstring}),instr({field.xmlstring},'<id>')+4,5)
I use the conditions to cover all possible lengths of the id number.

Parsing xml from forms6i,can anyone please help me

Can anyone please help me.I need to parse a xml file from a directory.The parsing should help me in giving a structure for two things.
1) i should be able to read the nodes( values between the tags) and display the values at my front-end textboxex
2) whenever the user changes the front-end content it should change the corresponding value in the xml node.
when it is finished i should be able to save the structure back as a xml file.This file is actually a blob object in the oracle database and is it wise to convert it into a file in dos directory and parse it from there or use oracle utilities from form6i and parse it from oracle utilities.
Please if someone can find help on this ,it would really help me.

No the password isn't your apple id password.
You encrypted your backup with a password, if you don't remember the password, then i'm sorry you won't be able to use it.

Parsing XML from a String

I have a servlet, this recieves an XML file from the client as a file input type from a html form. This XML is wrapped up in http headers and stuff. I parse the input stream from the client's http request to get a string containing the xml. This is fine.
How do I now build an XML document from this string? The DocumentBuilder will take in files and InputStreams but I can't find anything that helps me?
The only solution I've come up with is to write out the string to a temp file and then parse it back into a Document.
Any ideas anyone?????

Document doc = documentBuilder.parse(new InputSource(new StringReader(yourXMLString)));
voila!
