Character skips during XML Parsing

Hi,
I am SAX Parser for parsing XML files.
During parsing some times it skips the character.
e.g. if date come as 20091201 then it takes it as 091201.
During parsing in character I am storing this date into string variable
please do the helpful.
Thanks

Plain old programming, basic ordinary logic. If you want to collect all character data for an element:
(1) at the start of the element create an empty StringBuilder
(2) for each chunk of character data, append that to the StringBuilder (there's a convenient form of the append method whose parameters match the parameters of the characters method)
(3) at the end of the element, the StringBuilder contains all of the character data.

  • Memory Utilization during XML Parsing

    We have a slow response time during XML Parsing.
    Description of the problem:
    During XML parsing, memory is used and discarded so frequently that garbage collection
    is occurring multiple times per minute, impacting performance. In order to better
    understand the source of the memory usage issue, we used JProbe Memory Debugger.
    JProbe Memory Debugger was run in Aggregate mode in order to determine which classes
    were using the most total or aggregate memory (the sum of the memory required
    to instantiate not just a given object, but all the objects it uses.) The result
    was that weblogic.apache. xerces.impl.xs.dom.DocumentImpl and weblogic.apache.xerces.jaxp
    comprise 23.8% and 15.4%, respectively, of total memory on a heap of 121MB. In
    additional tests, the larger the heap, the greater these percentages were.
    This results in slow response time.
    The following are the details of software and Hardware configurations used:
    Server: weblogic 8.1
    OS: Solaris 8
    System Configuration: Sun Microsystems sun4u Sun Fire 6800
    System clock frequency: 150 MHz
    Memory size: 8192 Megabytes
    Please let me know if there is any work around or patches available.

    Sorry, I overlooked it.
    yes we do have 8 GB RAM. And as far as xml usage, we are parsing the xml to DOM
    (including validation) and then applying transformation. But its the parsing stuff
    which is eating the memory.1. Can you run JProbe to find out real CPU utilization/bottlenecks?
    2. Apache Xerses implementation that is used in weblogic has a design
    flaw that results in serialization of memory allocation by the transformer,
    that makes it impossible to use for intense multithreaded transformations.
    Consider using other transformers.

    Thanks Slava for youe response. Coming back to response time, thisprocess is part
    of a big task. So i cant really tell what response time i can allocatejust for
    this piece alone. Might be, roughly it should be less than 0.4 seconds.what the
    major concenr is the memory utilization by these packages. So whatmakes it to
    use this kind of memory and whether its a known issue ?

    Large heap means longer garbage collections. Anyway, DOM is very heavy
    on memory and you can not escape it. What's is your usage patternfor
    XML
    processing? Do you use XSL?
    This results in slow response time.What do you consider as acceptable/inacceptable responce time?

    What type of encoding are you using? Do you transform a string in an array of bytes or viceversa?

  • XML parser not detecting character encoding

    Hi,
    I am using Jdeveloper 9.0.5 preview and the same problem is happening in our production AS 9.0.2 release.
    The character encoding of an xml document is not correctly being detected by the oracle v2 parser even though the xml declaration correctly contains
    <?xml version="1.0" encoding="ISO-8859-1" ?>
    instead it treats the document as UTF8 encoding which is fine until a document comes along with an extended character which then causes a
    java.io.UTFDataFormatException: Invalid UTF8 encoding.
    at oracle.xml.parser.v2.XMLUTF8Reader.checkUTF8Byte(XMLUTF8Reader.java:160)
    at oracle.xml.parser.v2.XMLUTF8Reader.readUTF8Char(XMLUTF8Reader.java:187)
    at oracle.xml.parser.v2.XMLUTF8Reader.fillBuffer(XMLUTF8Reader.java:120)
    at oracle.xml.parser.v2.XMLByteReader.saveBuffer(XMLByteReader.java:448)

    at oracle.xml.parser.v2.XMLParser.parse(XMLParser.java:144)
    as you can see it is explicitly casting the XMLUTF8Reader to perform the read.
    I can get around this by hard coding the xml input stream to be processed by a reader
    XMLSource = new StreamSource(new InputStreamReader(XMLInStream,"ISO-8859-1"));
    however the manual documents that the character encoding is automatically picked up from the xml file and casting into a reader is not necessary, so I should be able to write
    XMLSource = new StreamSource(XMLInStream)
    Does anyone else experience this same problem?
    having to hardcode the encoding causes my software to lose flexibility.

    An XML document should be created with 'ISO-8859-1' encoding to be parsed as 'ISO-8859-1' encoding.

  • SQL Server 2012 Management Studio: Import XML File to SQL Table - XML parsing: illegal qualified name character

    Hi all,
    In my SQL Server 2012 Management Studio, I executed the following code:
    CREATE TABLE Products(
    sku INT Primary KEY,
    product_desc VARCHAR(30));
    INSERT INTO Products (sku, product_desc)
    SELECT X.product.query('SKU').value('.', 'INT'),
    X.product.query('Desc').value('.', 'VARCHAR(30)')
    FROM (
    SELECT CAST(x AS XML)
    FROM OPENROWSET(
    BULK 'H:\ZenProducts.xml',
    SINGLE_BLOB) AS T(x)
    ) AS T(x)
    CROSS APPLY x.nodes('Products/Product') AS X(product);
    SELECT sku, product_desc
    FROM Products;
    I got the following message:
    Msg 9455, Level 16, State 1, Line 5
    XML parsing: line 3, character 12, illegal qualified name character
    I have no ideas why the "product" in the statement "SELECT X.product.query('SKU').value('.','INT')" is not legal qualified name charcter!!!???  Please kindly help, advise and respond.
    Thanks in advance,
    Scott Chang

    Hi Manish, Thanks for your response.
    Here is a copy of my ZenProducts.xml:
    <Products>
    <Product>
    <SKU>1<</SKU>
    <Desc>Book</Desc>
    </Product>
    <Product>
    <SKU>2<</SKU>
    <Desc>DVD</Desc>
    </Product>
    <Product>
    <SKU>3<</SKU>
    <Desc>Video</Desc>
    </Product>
    I found the wrong "<<" in my xml file and changed it to the right "<" for the statement<SKU>1</sku>. I executed the corrected code and I got the following new message:
    Msg 2714, Level 16, State 6, Line 1
    There is already an object named 'Products' in the database.
    I don't know how to remove the old, existing the 'Products' object in the database and execute the corrected code again. Please kindly help, advise and tell me how to resolve this new problem.
    Many Thanks,
    Scott Chang
    P. S. I played with another project to get the 'Products' object in my database before. Frankly, I don't know where the old 'Products' object and the database are. Please enlighten me in resolving this matter more clearly.
    You welcome Scott, As Olaf mentioned in this post, there was already a table exists , so need to drop your Products table.
    Apart from this, I guess either you did not pasted the full XML file or what, I needed to have the (  </Products>)closing tag in your XML file as follows.
    <Products>
    <Product>
    <SKU>1</SKU>
    <Desc>Book</Desc>
    </Product>
    <Product>
    <SKU>2</SKU>
    <Desc>DVD</Desc>
    </Product>
    <Product>
    <SKU>3</SKU>
    <Desc>Video</Desc>
    </Product>
    </Products>
    You can use following script to drop if your 
    Products table is already existing.
    if exists(select 1 from sys.tables where name ='Products')
    drop table Products
    CREATE TABLE Products(
    sku INT Primary KEY,
    product_desc VARCHAR(30));
    INSERT INTO Products (sku, product_desc)
    SELECT X.product.query('SKU').value('.', 'INT'),
    X.product.query('Desc').value('.', 'VARCHAR(30)')
    FROM (
    SELECT CAST(x AS XML)
    FROM OPENROWSET(
    BULK 'H:\ZenProducts.xml',
    SINGLE_BLOB) AS T(x)
    ) AS T(x)
    CROSS APPLY x.nodes('Products/Product') AS X(product);
    SELECT sku, product_desc
    FROM Products;
    Let us know if you face any other problem.

  • Xml parsing error: invalid character

    We started receving below error while opening PDF forms in the browser , its started happening from today for several users.   They were using IE and Adobe Reader 10.1
    Any one saw  this error before?
    xml parsing error: invalid character number (error code 14), line 3 , column 264  of file....

    We can see this issue only in Adobe Reader XI (11.0.01), X (10.1.5) And 9.5.3 in OS Win XP and 7.0. This happens only in IE. Fire Fox it works fine.
    We rolled back to Adobe Reader 10.1.3 , works perfect.

  • XI XML Parser: tag content with "'", single apostrophe: invalid character

    Hi all,
    we import XML-documents with the file adapter in a sender channel. everything works well.
    But if one of the XML-tag contents contains a single apostrophe ( ' ), then the XML parser stops with an error "An invalid character was found inside an entity reference. ". The message can not be processed. If I test the message content in the mapping -> no error.
    When the single apostrophe is dereferenced by an additional single apostrophe the XML-File can be processed.
    Question: does anybody know how this can be handled because it is not very nice of SAP XI to send single apostrophes in outgoing messages but cannot handle it in incoming messages from other systems? special adapter settings?
    Thank you very much

    I have seen this error when I'm executing inside one of the (j2ee sun reference implementation) server containers (either web or ejb). I believe its caused by "something" having previously loaded the "sax 1 driver class". In my case, I think the container or server is loading the sax parser from a jar that contains a sax 1 version. If you can, ensure that nothing is loading the sax 1 parser from another jar on your system. Verify that you are loading the sax parser from a jar containing the latest version so that you get the sax 2 compliant parser. Good luck!

  • Problem in XML Parsing via oracle procedure...

    Hi,
    I wrote one oracle procedure for xml parsing.
    I have one valid xml file which has "encode UTF-8". The XML file contains some comments also. While we are parsing the xml file at that time it is not parse successfully and also it is not giving any error. After the following line it is skip rest of the codes(lines).
    dbms_xmlparser.parseclob(l_parser, l_clob);
    At the end of the xml file there are some comments which is like "<!-- abc --> ".
    When I am changing the "encode UTF-8 to ISO-88596-1" & removing the comments which wrote on bottom of the file then its working fine, but the files which we are getting from the system is contains the encode UTF-8 and we don't want to preprocess on that xml files. Even if we will do that via shell script or perl script then it will be overhead to the system and in a single stroke our system will parse more than 5k xml files, so if we will do some preprocess on it, it will take some more time approx 1-2 minutes extra.
    So, If someone knows any solution of this problem, then please guide & help me on this.
    My xml file structure is as follows:-

    Sorry Odie,
    I am new to this site as well as PL/SQL. I am giving additional details which you had mentioned in your last comments.
    our Oracle Database version is "10.2.0.4.0"
    The structure of target table Instrument_Details is as follows:
    Create table Instrument_Details (
    instrument_id          Integer  Primary Key,
    provider_name          Varchar2(32),
    version_number          Varchar2(32),
    location_id                  Integer,
    installation_date             Date,
    granularity                  Integer,
    time_out                  Integer );
    Note:- Here test_hem is alias of Instrument_details.
    Here instrument_id is a primary key.
    provider_name contains the child2 xml tag value.
    version_number contains the child1 xml tag value.
    location_id contains the newid/id value which is map to other table which fetching the location name corresponding to the location_id.
    installation_date contains the date xml tag value.
    Now we have created one mapping tables where we mapped the xml tag values "mt" with table column name means "abc1 = granularity", "abc2 = time_out" in that table.
    these table column value are written under mvalue xml tag.
    _Our Database Character set is_:-
    NLS_CHARACTERSET WE8ISO8859P1
    Now as you suggest me to format your code. I am writing the xml code and procedure code again.
    My xml file structure is as follows:-
    <?xml version="1.0" encoding="UTF-8"?>
    <mcd xmlns:HTML="http://www.w3.org/TR/REC-xml">
      <child>
          <child1>32.401 V5.5</child1>

      </child>
      <mc>
          <newid>
               <id>12</id>
          </newid>
      <mindex>
           <date>20111102180000</date>
           <mt>abc1</mt>
           <mt>abc2</mt>
           <mvalue>
                 <r>val_1</r>   -- here val_1 and val_2 are numeric values
                 <r>val_2</r>
            </mvalue>

  • Attempt to process file failed with Exception in XML Parser-format problem

    Hi all,

    My scenerio iam posting IDOC to a flat file with content conversion in the receiver side,the mapping got executed successfully and in the audit log i found that the error was after the 'Start converting XML document content to plain text'.
    This means that error occured during content conversion of XML to the prescribed file format.
    Can anyone suggest any better approach using which we may trace the junk data in IDoc. Manual adhoc approach could take time and is error prone.
    Thanks in advance...

    Hi Bhavesh,
    Thanks for the early reply. I checked the mapping and everything is fine and the output is also in valid XML format.
    The audit log shows that the mapping got executed successfully and the error is after the step 'Start converting XML document content to plain text '. Is there any constraint in the file adapter regarding the message size for parsing.
