Applying XSL on a XML string

Hi,
I am a newbie to XML and XSL.
I am getting an XML as a String, I want to apply a XSL on it.
a) Because I don't have any StreamSource can I apply an XSL on that String directly, Is there any API for it?
b) If we cannot apply directly on a String then how to address this issue?
This may be very common issue, but I am not getting any help on it.
Please help me on this?
Thanks in advance
Vikas

Yes, it's a very very common question here. I am surprised you didn't find the answer when you searched the forum because it is very very often posted.
I don't know why you say you don't have a StreamSource. Why don't you just create one?
new StreamSource(new StringReader(yourXMLString))

Hi Edwin,
You need to recompile the xml forms project and that should resolve the issue. Unfortunately there is no alternative solution in such a scenario.

How to apply Xsl to the xml value stored in ResultSet

String url = "jdbc:msql://200.210.220.1:1114/Demo";
Connection conn = DriverManager.getConnection(url,"","");
Statement stmt = conn.createStatement();
ResultSet rs;
rs = stmt.executeQuery("SELECT Lname FROM Customers for auto xml");
// I want to convert the content of this rs into a String or StringBuffer and apply sxlt to format the data. Can anyone help me.
Thanks

In your view you could do something like that:
foreach (var field in Model.FormStruture.fields)
<div class="editor-label">
<label for="@field.Name">@field.Descricao</label>
</div>
<div class="editor-field">
<input class="text-box single-line" id="@field.Name" name="@field.Name" type="text" value="@field.Valor" data-rules-required="@field.Mandatory.ToString().ToLower()" data-rule-number="@field.Tipo.Equals(SiB.OCR.Documentos.Modelo.TipofieldDocumento.Numerico).ToString().ToLower()" title="@field.Descricao" />
</div>
if (!String.IsNullOrEmpty(field.Format))
@:<script type="text/javascript">$("[email protected]").mask("@field.Format");</script>

Converting SQL Server text field containing XML string to XI XML via JDBC

Hello
My client has a SQL Server database containing a field of type Text which contains an XML string e.g.
<DispatchJob> <DispatchDateTime>2003-09-29T13:29:15</DispatchDateTime> <AssignedFSE>F118</AssignedFSE> <DispatchJobPurchase> <DealerID>14C5</DealerID> <DateOfPurchase>1997-10-01T00:00:00</DateOfPurchase> </DispatchJob>
I am using JDBC to access this but could someone please recommend the best and easiest solution for converting this string to XI XML for subsequent mapping to BAPI or IDOC or ABAP Proxy and transmission to SAP. There are other fields as well in the database table so thoughts at the moment are to use a normal graphical message mapping followed by an XSL mapping. Will an XSL mapping be able to do this and if so is that the best solution?
Also I need to do the reverse of this and take fields coming from SAP via BAPI,IDOC etc. and convert them to a single database table field as an XML string also via the JDBC adapter. What is the best way to do this. Could it be done simply with functions in the graphical mapping e.g. concatenate?
Thank you in advance.
Trevor

Hi Michal
Thanks for the prompt reply.
I was anticipating XSLT for reading from the SQL Server database and converting the XML string.
But how would you convert the individual fields from SAP into a single field as an XML string for storing in the SQL Server database? What approach would you use?
Regards
Trevor

Parsing an xml string into id-value pair format

Hi,
I am new in oracle BPEL.
My requirement is that I need to parse an xml string containing tag name and coressponding value into an 'id -value' pair.
For example-
The input xml format is -
<employee>
<empid>12345</empid>
<name>xyz</name>
<city>London</city>
</employee>
The required xml format is-
<employee>
<item id="empid" value="12345"/>
<item id="name" value="xyz"/>
<item id="city" value="London"/>
</employee>
Please let me know if there is a work-around for this.
Thanks

Something like this (have not tested):
<xsl:for-each select="//employee">
<employee>
<xsl:for-each select="./*">
<item>
<xsl:attribute name="id">
<xsl:value-of select="name()"/>
</xsl:attribute>
<xsl:attribute name="value">
<xsl:value-of select="text()"/>
</xsl:attribute>
</item>
</xsl:for-each>
</employee>
</xsl:for-each>

Convert XML string into XML

Hi All,
Can you please let me know for any sample code in xslt/java mapping for converting XML string into XML. We use SAP Pi 7.0
My XML string starts like this
<?xml version="1.0" encoding="UTF-8" ?>
- <ns0:MT_ReceiverFileStructure <namespace>"><Output><?xml version="1.0" encoding="ISO-8859-9"?><?xml-stylesheet type="text/xsl" href="<xsl>"?><Tarih_Date Tarih="11.09.2014" Date="09/11/2014>
Thanks,
Pavithra

Thanks Praveen. It worked.
However, the xml i have is an extract from a exchange rate URL and it has the reference to a xsl in it as below
<?xml version="1.0" encoding="ISO-8859-9"?><?xml-stylesheet type="text/xsl" href="<ABC.xsl>"?>.
So there is an error in sxmb_moni. Is it possible to remove this.

Is there a way to get the actual XML string when using the JAXP SAX Parser?

Hi All,
I am using a JAXP SAX xml parser and am looking for a way to get the actual line of xml that is being parsed from within a content handler.
Here's my scenario. Consider the following example xml document.
<formCollection>
   <form name="myForm">
      <text/>
      <selection/>
   </form>
   <form name="anotherForm">
      <text/>
   </form>
</formCollection>My hope is to validate the entire document and then insert an xml string containing each "form" element (and its sub-elements) into a map for later use. My thought was to create a String as each "form" element is being parsed (begining with the form's startElement event and concatenating until the form's endElement event is reached) and then inserting this string into the map. Is there a way to get the actual line of xml that is being parsed, rather than just the element name and attribute values?

2. The first handler would validate the entire XML document, extract the "type" attribute from each <form> element, and place each <form> element and its sub-elements into the map of Strings, using the "type" attribute as the key. The second handler would take a <form> element and parse it into a Form object for the display. This option was the impetus for my question because it relies on the first handler being able to access the entire <form> element XML String and write it to a map.I don't see why you need the raw data from the XML document here. You should already be abstracting your data into Java classes in the first handler, instead of making the second handler do the parsing all over again.Correct, I am not referring to XForms. In this case, it happens that I am using the XML to generate an SWT ScrolledForm object and, thus, the XML element name happens to be named "form." However, the concept/design problem could apply to any type of object and the XML element could be appropriately renamed.
My experience with XSLT is limited and I haven't done anything with it for several years. With that said, it seems that it is primarily used for generating web content, which wouldn't apply in this case because this is for a client-server application. I could be off base on this one -- if XSLT applies to much broader translations and would be more appropriate for generating Java objects than my current methodology, I could certainly look into it further.
I apologize that option two didn't make more sense; it is difficult to explain. Yes, optimally the data should be abstracted into Java classes in the first handler. This is really an elaboration that I failed to specify when explaining option one. The problem is that the user can choose to create any number of "forms" of any type. For instance, let's say that from the File -> New menu there are options for seven different types of forms and each form is used to send completely different data. The user can select form1, select form1 again, select form4, and select form7 (or any other combination) and bring up tabs that display the different forms. The user can then enter data and submit each form separately. When the user selects File -> New -> FormX, a SWT ScrolledForm object that corresponds with FormX must be given to the display. Because SWT ScrolledForm objects do not allow a deep copy, I cannot simply read the XML <form> elements at initialization, parse them into ScrolledForm objects, and pass deep copies of the ScrolledForm objects to the display each time the user clicks File -> New -> FormX. The only simple way I see of getting a new copy of a ScrolledForm object is to reparse the appropriate XML <form> element in order to create one each time the user selects File -> New -> FormX. As such, one handler would need to read the entire XML document and parse the <form> elements into a map (or some other data structure) and another handler would need to parse individual <form> elements into SWT ScrolledForm objects. The first handler would be called at initialization and the second handler would be called each time a user clicked on File -> New -> FormX. Once again, this isn't exactly my favorite implementation... but seems the simplest given that there is no way to do a deep copy of an SWT ScrolledForm object. Hopefully that makes a little more sense. No worries if it doesn't -- I just figured I'd throw this out there and see if anyone had a better idea.

Problem in producing some xml strings

Dear all,
I got a problem in producing some xml string. I use the DocumentBuilderFactory and DocumentBuilder to build a xml document. Instead of saving to a file, I need to make it into a string then return it to the caller. I have tried to use the Transformer but the string returned contains the <?xml version=..../> line which I don't want it. What can I do?

What you want to do is associate a stylesheet with the transformer instance you are using to place the DOM into string. The stylesheet with the appropriate instructions are get rid of the <?xml version=..>. You want to produce a stylesheet which has:
<xsl:output omit-xml-declaration="yes"/>
<xsl:template match="/">
<xsl:copy-of select="node()"/>
</xsl:template>
<xsl:output> controls the serialisation of the xml document to the output source which in this case is a string. The <xsl:template> is required. It will copy the entire xml document to the output source. Without it the default templates are used, and the xml markup will not be included in the output source.
Hope this helps.

Applying REGEX-pattern into XML File

I have the following problem:
I have an xml-file. let's say...
<NODE><NODE1 attr1="a1" attr2="a2">
     <NAME> abc</NAME>
     <VERSION> 1.0</VERSION>
</NODE1>
<NODE2 attr1="a3" attr2="a4">
     <NAME> xyz</NAME>
     <VERSION> 3.1</VERSION>
</NODE2></NODE>I need to know "HOW can I get the values of <NAME></NAME> and <VERSION></VERSION> without using DOM.
Since my xml-file is pretty big and DOM will take much Memory, i want to avoid it.
Can anybody suggest some "Regex pattern" so that i can apply it on the xml-file (after converting into String)
Thanks in Advance

That worked perfectly. I assumed ( insert comment here ) that the members of the Properties objects were Strings, and therefore followed the same rules where "\" characters are concerned.
Thank you for pointing out the difference between the two objects, I am not sure how long it would have taken me to figure that out.

Handling long XML strings in XSLT

I am creating an XML string dynamically to feed to my XSLT processing servlet. In a prototype I did this by passing the XML as a string to a routing servlet that then calls HttpResponse.sendRedirect() with the name of the XSLT processing servlet and the XML string like this :
redirectString = "/WardenConfig/servlet/XSLTServlet?xslPage=" + nextPage + "&xmlSourceString=" + XMLData ;
where XMLData is the dynamically built XML and nextPage is an XSL stylesheet. Then I send use this to send it all to the servlet that processes the XSL and displays the result :
response.sendRedirect( redirectString );
The problem is that when I get a lot of data in the XML string this does not work. I think this might be because sendRedirect() uses the GET method but I am not sure. SO I had two questions :
1) Is that the problem - the GET method, I mean ?
2) What's a better way to do this ?
thanks in advance !!

Will do, Doctor. I appreciate your quick help ! Is that the way most people handle this ?
By the way, if you can tell me how to award Duke Dollars, I would like to do that. For some reason I can't do it anymore .. used to be able to ... feel lame ...
Thanks again.

Hi,
You can find a few methods here : How To : Update XML nodes with values from the same document | Odie's Oracle Blog
They're not all applicable to your version and settings though.
Here's the first one applied to your case :
declare
v_xmldoc   xmltype;
begin
select xmlparse(document to_clob(t.xmldoc))
into v_xmldoc
from my_nclob_table t
where t.id = 1;
for r in (
    select idx, schema_name
    from my_nclob_table t
       , xmltable(
           '/set/configuration'
           passing v_xmldoc
           columns idx         for ordinality
                 , schema_name varchar2(30) path 'property[@name="jdbc.schema"]/@value'
loop
    select updatexml(
             v_xmldoc
           , '/set/configuration['||to_char(r.idx)||']/property[@name="password"]/@value'
           , r.schema_name || '01'
    into v_xmldoc
    from dual ;
end loop;
update my_nclob_table t
set t.xmldoc = to_nclob(xmlserialize(document v_xmldoc indent))
where t.id = 1;
end;
Here's another one, using DOM :
declare
doc   clob;
p        dbms_xmlparser.Parser;
domdoc   dbms_xmldom.DOMDocument;
docnode dbms_xmldom.DOMNode;
conf_list      dbms_xmldom.DOMNodeList;
conf_node      dbms_xmldom.DOMNode;
password_node dbms_xmldom.DOMNode;
schema_name     varchar2(30);
password_value varchar2(256);
begin
select to_clob(xmldoc)
into doc
from my_nclob_table
where id = 1 ;
p := dbms_xmlparser.newParser;
dbms_xmlparser.parseClob(p, doc);
domdoc := dbms_xmlparser.getDocument(p);
dbms_xmlparser.freeParser(p);
docnode := dbms_xmldom.makeNode(domdoc);
conf_list := dbms_xslprocessor.selectNodes(docnode, '/set/configuration');
for i in 0 .. dbms_xmldom.getLength(conf_list) - 1 loop
    conf_node := dbms_xmldom.item(conf_list, i);
    dbms_xslprocessor.valueOf(conf_node, 'property[@name="jdbc.schema"]/@value', schema_name);
    password_node := dbms_xslprocessor.selectSingleNode(conf_node, 'property[@name="password"]/@value');
    dbms_xmldom.setNodeValue(password_node, schema_name || '01');
end loop;
dbms_xmldom.writeToClob(domdoc, doc);
dbms_xmldom.freeDocument(domdoc);
update my_nclob_table t
set t.xmldoc = to_nclob(doc)
where t.id = 1;
end;

Generating XML String

I may have missed something obvious but the SAX & DOM bits of
the XML Parser don't seem to supply any way of getting from a
set of parsed (or created) Document Java objects to a marked up
XML string. Is this something we have to do ourselves by
navigating through the node tree and adding the necessary
markup? It seems generic enough to be provided by one of your
APIs (such as the XSL bits?).
Thanks,
Dave

Thanks,
I found the print method on the XMLDocument class which
generates an encoded string from that XMLDocument. This is fine
but what I had was a DocumentFragment reference returned from
the XSLProcessor.
I assume you have to get an XMLDocument from this
DocumentFragment (since XMLDocument doesnt implement that
interface) by creating an empty XMLDocument and then appending
the DocumentFragment as a child element. You can then use the
print method to get the XML string containing the styled XML.
This seems to work ok. Is this the right way to go about it?
Cheers,
Dave

Performance problem submitting big XML string parameter to the web service

We deployed a web service on the OC4J via oracle.j2ee.ws.StatelessJavaRpcWebService . This web service takes one string as a parameter. The string contains XML. Evrything works great UNLESS input XML string reaches 5Mb in size. When it happens OC4J does something with it for about 10 minutes (yes, minutes) before it calls the web service method. At this time java.exe consumes 100% of CPU.
WE tried to increase JVM heap size, stack size, etc, - no effect.
Please, help!
Thank you in advance,
Vlad.

Hi Sheldon,
What i feel is that it's not been handled in your webservice if the parameter is null or "" <blank> space
i just you to take care in webservice that if the parameter is null or "" pass the parameter null to the stored proc
