URGENT Parsing nd Searching XML with DOM

Hi,
I am Juliana, I am a new grad, a new employee and brand new to XML, I am learning to parse XML with the XML parser for PLSQL.
Please anyone help me how to parse the following XML string so that I will display all the session and its time schedule, or if possible display only the session that I want to display.
Thank you very much for any of your help

I put dom storage on "false" and now I can't do a Google search. A few days ago I could search Google with dom on false. What changed?

I customized the Firefox using 'about:config' and all the other settings work well with Google search - for example geo_enabled which I set to false.
The one setting that has suddenly proved problematic is dom_storage. I used it in false mode successfully for months when searching on Google, now the setting has resulted in an inability to search on Google. The Google page with search bar comes up as usual when I open the browser, but with dom storage set to "false" I can't search anything - the Google search bar page just remains static.

Users who disable DOM storage in IE8 and IE9 are reporting the same problem on Google's web search forum. For that reason, the requirement to allow DOM storage sounds like a change in Google's code rather than a browser-specific issue.
One Firefox-specific issue is the cookie connection: Firefox appears to use cookie permissions to block DOM storage on a site-by-site basis. So if you block cookies for google.com, the DOM storage problem will kick in.

}The questions i have are really simple.
1) I am trying to get a specific value from the xml.
for example the <title> after <channel> but i want only this title not the others as well. I can all the titles but i cant get it right for returning only the first. What am i doing wrong?
2) i also want to parse the same values that are in the <item> for all 3 items but when i am using the
               if(node.getNodeName().equals("link")){
                 Node fc = node.getFirstChild();
                 System.out.println("the link: "+ fc.getNodeValue());}i get a nullPointerException because the first link is empty under the <title>. If i change it to <description> it works fine.
The fact is that i dont know how to point it to look a specific tags like only in <item>
I have some comments in there of the different things i tried...
Any suggestions??? Pleaseeeee.... :)

Urgent help in searching XML docs

Hi All,
I have started using JDOM and created a XML document after reading the contents from a text file. Now i need to implement a search facility on this XML document. The structure of my XML document is given bellow
<Company ID="C1">
<Name>aa</Name>
<Address>qq</Address>
<Contact_Person>ww</Contact_Person>
<Designation>ee</Designation>
<Phone>123</Phone>
<Fax>456</Fax>
<EMail>acd</EMail>
<Website>axc</Website>
<Business_Type>hfs</Business_Type>
<Operation_Areas>khgd</Operation_Areas>
<Other_Info>csbdcks</Other_Info>
</Company>There are similar company nodes having information about different companies.
The search criteria can be based on any one node e.g search companies by <Location> or <Business_Type> etc. I am planning to use XSL and pass the search parameters. Is the approach right?? Could someone guide me with some code examples .
Thanks in advance..
Nilotpal

If you want to search information in a JDom object, you can use XPath with Jaxen: http://www.jaxen.org/
I never used Jaxen, so I can't help you.
But with XPath you can implement many search facilities.

Can I parse non-wellformed XML with SAX at all?

Hi all,
i was wondering whether its possible at all to parse XML that is not well formed with SAX.
e.g. A HTML file that doesnt close tags and stuff like that.
I tried implementing the fatal() method of the Handler in a a way that it consumes the exception but does not rethrow it.
Also I tried setting the validation property to false. Both with no success.
Any help would be appriciated.
thx
philipp

Your experiments tell you the answer.
If you have HTML tag soup, why not just run it through JTidy or HTMLTidy to make it into well-formed XHTML?

How to parse data from XML with prefix?

Hi folks,
I have an XML which tags include prefixes. I would like to parse it using a select. Any ideas?

Build XML with DOM

Why does this loop works well if I COMMENT OUT the second node -
but I get a NULL document if I try to add the second node ?
//Loop through the result set
for (int i=0; i < iRows; i++) {
System.out.println(result.getString("SiteID"));
Node newSiteIDNode = document.createElement("SiteID");
Text tnSiteIDNode = document.createTextNode(result.getString("SiteID"));
newSiteIDNode.appendChild(tnSiteIDNode);
root.appendChild(newSiteIDNode);
Node newItemNode = document.createElement("ItemCode");
Text tnItemNode = document.createTextNode(result.getString("ItemCode"));
newItemNode.appendChild(tnItemNode);
root.appendChild(newItemNode);

The XML file that I'm creating via the following is empty
TransformerFactory transFactory =TransformerFactory.newInstance();
Transformer transformer = transFactory.newTransformer();
// Using the DOM tree root node, the following line of code constructs a DOMSource object as the source of the transformation.
DOMSource source = new DOMSource(document);
// The following code fragment creates a StreamResult object to take the results of the transformation
// and transforms the tree into an XML file.
newXML = new File("FTHSites.xml");
FileOutputStream os = new FileOutputStream(newXML);
resultXML = new StreamResult(os);
transformer.transform(source, resultXML);

Persisting unexplained errors when parsing XML with schema validation

Hi,
I am trying to parse an XML file including XML schema validation. When I validate my .xml and .xsd in NetBeans 5.5 beta, I get not error. When I parse my XML in Java, I systematically get the following errors no matter what I try:

ii) Document is invalid: no grammar found.

Any ideas? Thanks !!!
J�r�me Verstrynge

Hi,
I found the solution in the following post:
Validate xml with DOM - no grammar found
Sep 17, 2003 10:58 AM
The solution is to add a line of code when parsing:
try {
Document document;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(true);
factory.setNamespaceAware(true);
factory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");
DocumentBuilder builder = factory.newDocumentBuilder();
document = builder.parse( new File(PathToXml) );
The errors are gone !!!

Since OC4J is preconfigured to use the Oracle XML parser which is xmlparserv2.jar.
i have read the following article which states that
OC4J is preconfigured to use the Oracle XML parser. The Oracle XML parser is fully JAXP 1.1 compatible and will serve the needs of applications which require JAXP functionality. This approach does not require the download, installation, and configuration of additional XML parsers.
The Oracle XML parser (xmlparserv2.jar) is configured to load as a system level library of OC4J through it's inclusion as an entry in the Class-Path entry of the oc4j.jar Manifest.mf file. This results in the Oracle XML parser being used for all common deployment and packaging situations. You are not permitted to modify the Manifest.mf file of oc4j.jar.
It must be noted that configuring OC4J to run with any additional XML parser or JDBC library is not a supported configuration. We do know customers who have managed to successfully replace the system level XML parser and the Oracle JDBC drivers that ship with the product, but we do not support this type of configuration due to the possibility of unexpected system behavior and system errors that might occur from replacing the tested and certified libraries.
If you absolutely must use an additional XML parser such as xerces, then you have to start OC4J such that the xerces.jar file is loaded at a level above the OC4J system classpath. This can be accomplished using the -Xbootclasspath flag of the JRE.
i have also run the following command
java -Xbootclasspath/a:d:\xerces\xerces.jar -jar oc4j.jar
but no success.
How could i utilize my jar's like xerces.jar and xalan.jar for parsing instead of OC4J in-built parser ?
All reply will be highly appreciated.
Thnx in advance to all.

Hi Neeraj Sidhaye,
I am trying to deploy a sample xform application to the Oracle Application Server (10.1.3). However, I encountered the class loader issue that is similar to your stuation. I tried all the three solutions but the application is still use the Oracle xml paser class. I am wondering if you have any insight about this?
Thanks for your help.

To convert XML to ABAP internal table can we do it with DOM or we need XSLT

I have a requirement where I need to collect the data from XML file into an internal table.
I need to collect this data into an internal table as I should make use of this data and do Goods Receipt in SAP.
My XML file is very very complex and the child nodes in my XML file may occur ones or 10 times and change dynamically.
I want to know if XML to ABAP internal table is possible with DOM or does it need XSLT too.
I used the blog of Robert which uses DOM, but it I am unable to collect the data in internal table. The blog explains only how to wtite the out put to screen as element and value.
I want to know if XML to ABAP internal table is possible with DOM or do I need XSLT too? I am confused please help.
Any help will be highly appreciated.

Jessica Sam

Hello Jessica
Why not using the DOM itself for processing?
Below you see the post-processing coding which I use to add the interchange control number (ICN) into an EDI message (which at this stage is still an XML-EDI stream). This is done on SAP-XI yet on the ABAP stack so you could use this approach on your R/3 system as well.

In your case you would need to do a DO...ENDDO loop until you parsed all required nodes.
NOTE: ME->MO_DOCUMENT is of TYPE REF TO IF_IXML_DOCUMENT.

Parsing an XML using DOM parser in Java in Recursive fashion

I need to parse an XML using DOM parser in Java. New tags can be added to the XML in future. Code should be written in such a way that even with new tags added there should not be any code change. I felt that parsing the XML recursively can solve this problem. Can any one please share sample Java code that parses XML recursively. Thanks in Advance.

Actually, if you are planning to use DOM then you will be doing that task after you parse the data. But anyway, have you read any tutorials or books about how to process XML in Java? If not, my suggestion would be to start by doing that. You cannot learn that by fishing on forums. Try this one for example:

Parsing xml using DOM parser in java

hi there!!!
i don have much idea about parsing xml.. i have an xml file which consists of details regarding indentation and spacing standards of C lang.. i need to read the file using DOM parser in java n store each of the attributes n elements in some data structure in java..
need help as soon as possible!!!

DOM is the easiest way to parse XML document, google for JDOM example it is very easy to implement.
you need to know what is attribute, what is text content and what is Value in XML then easily you can parse your document with dom (watch for space[text#] in your XML document when you parse it).
you get root node then nodelist of childs for root then go further inside, it is easy believe me.

XSLT with DOM/C++ Parser

Help,
Anyone familiar with xslprocess class with DOM Parser for C++? My application needs to transform the original XML document, and then parse the new document (parse elements in tree). The example in the XDK demo directory (XSLSample.cpp) stops short of this. This demo/sample code simply output the newly transformed to the standard output (screen). My attempt to parse the newly transformed XML has been unsuccessful. Most of my code is base direcly from the sample:
void
DbXMLLoad::transformXML( const string& filename)
xmlpar.xmlinit();
strcpy(xml_doc, (char*)filename.c_str());
xmlpar.xmlparse((oratext *), xml_doc, (oratext *) 0, flags);
xslpar.xmlinit();
strcpy(xsl_doc, "it2xxx.xsl");
xslpar.xmlparse((oratext *), xsl_doc, (oratext *) 0, flags);
respar.xmlparse((oratext *) result, (oratext *) 0, flags);
xslproc.xslprocess(&xmlpar, &xslpar, &respar, &result);
xslproc.printres(&respar.getDocumentElement(), 1);
// Parse the newly transformed XML document????
constructTree(result, 1);
(void) xmlpar.xmlterm();
(void) xslpar.xmlterm();
(void) respar.xmlterm();
void
DbXMLLoad::constructTree(Node *node, word level)
if (node) {
dumpTree(node, level);
if ((node->getType() !=DOCUMENT_TYPE_NODE) && node->hasChildNodes()) {
nodes = node->getChildNodes();
n_nodes = node->numChildNodes();
for (i=0; i< n_nodes; i++)
constructTree(nodes->item(i), level + 1);
void
DbXMLLoad::dumpTree(Node *node, uword level)
switch (node->getType()) {
case ELEMENT_NODE: // start database processing
case TEXT_NODE: // continue database processing
default:
Appreciate your help. Thanks in advance

what is "respar"?What version of XDK do you use?
