How can we get tag of XML file using SAX

Hi ,
I'm parsing one SAX parser , I'have almost done this parsing. i have faced problem for one case, i'e how can we get tag from XML file using SAX parser?
XML file is
<DFProperties>
<AccessType>
<Get/>
</AccessType> <Description>
gdhhd
</Description>
<DFFormat>
<chr/>
</DFFormat>
<Scope>
<Permanent/>
</Scope>
<DFTitle>gsgd</DFTitle>
<DFType>
<MIME>text/plain</MIME>
</DFType>
</DFProperties>
I want out like GET and Permanent... means this one tag which is present inside of another tag.
Handler class like
public void startElement(String namespaceURI, String localName,
               String qName, Attributes atts) throws SAXException {

How 2 get the path of a file Using jsp

how 2 get the path of a file Using jsp
i have tried getPath...but i'm geting the error
The method getPath(String) is undefined for the type HttpServletRequest
any idea how 2 get the path of a file

You need ServletContext#getRealPath().

How can i write also to xml file the settings of the Tag property to identify if it's "file" or "directory" ?

The first thing i'm doing is to get from my ftp server all the ftp content information and i tag it so i can identify later if it's a file or a directory:
private int total_dirs;
private int searched_until_now_dirs;
private int max_percentage;
private TreeNode directories_real_time;
private string SummaryText;
private TreeNode CreateDirectoryNode(string path, string name , int recursive_levl )
var directoryNode = new TreeNode(name);
var directoryListing = GetDirectoryListing(path);
var directories = directoryListing.Where(d => d.IsDirectory);
var files = directoryListing.Where(d => !d.IsDirectory);
total_dirs += directories.Count<FTPListDetail>();
searched_until_now_dirs++;
int percentage = 0;
foreach (var dir in directories)
directoryNode.Nodes.Add(CreateDirectoryNode(dir.FullPath, dir.Name, recursive_levl+1));
if (recursive_levl == 1)
TreeNode temp_tn = (TreeNode)directoryNode.Clone();
this.BeginInvoke(new MethodInvoker( delegate
UpdateList(temp_tn);
percentage = (searched_until_now_dirs * 100) / total_dirs;
if (percentage > max_percentage)
SummaryText = String.Format("Searched dirs {0} / Total dirs {1}", searched_until_now_dirs, total_dirs);
max_percentage = percentage;
backgroundWorker1.ReportProgress(percentage, SummaryText);
percentage = (searched_until_now_dirs * 100) / total_dirs;
if (percentage > max_percentage)
SummaryText = String.Format("Searched dirs {0} / Total dirs {1}", searched_until_now_dirs, total_dirs);
max_percentage = percentage;
backgroundWorker1.ReportProgress(percentage, SummaryText);
foreach (var file in files)
TreeNode file_tree_node = new TreeNode(file.Name);
file_tree_node.Tag = "file";
directoryNode.Nodes.Add(file_tree_node);
numberOfFiles.Add(file.FullPath);
return directoryNode;
The line i'm using to Tag is:
file_tree_node.Tag = "file";
So i know what is "file" then i make a simple check if the Tag is not null then i know it's a "file" if it's null then it's directory.
For example this is how i'm checking if it's file or directory after getting all the content from my ftp server:
if (treeViewMS1.SelectedNode.Tag != null)
string s = (string)treeViewMS1.SelectedNode.Tag;
if (s == "file")
file = false;
DeleteFile(treeViewMS1.SelectedNode.FullPath, file);
else
RemoveDirectoriesRecursive(treeViewMS1.SelectedNode, treeViewMS1.SelectedNode.FullPath);
I also update in real time when getting the content of the ftp server xml file on my hard disk with the treeView structure information so when i'm running the program each time it will load the treeView structure with all directories and files.
This is the class of the xml file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
using System.Windows.Forms;
namespace FTP_ProgressBar
class TreeViewXmlPopulation
// Xml tag for node, e.g. 'node' in case of <node></node>
private const string XmlNodeTag = "node";
// Xml attributes for node e.g. <node text="Asia" tag=""
// imageindex="1"></node>
private const string XmlNodeTextAtt = "text";
private const string XmlNodeTagAtt = "tag";
private const string XmlNodeImageIndexAtt = "imageindex";
public static void DeserializeTreeView(TreeView treeView, string fileName)
XmlTextReader reader = null;
try
// disabling re-drawing of treeview till all nodes are added
treeView.BeginUpdate();
reader = new XmlTextReader(fileName);
TreeNode parentNode = null;
while (reader.Read())
if (reader.NodeType == XmlNodeType.Element)
if (reader.Name == XmlNodeTag)
TreeNode newNode = new TreeNode();
bool isEmptyElement = reader.IsEmptyElement;
// loading node attributes
int attributeCount = reader.AttributeCount;
if (attributeCount > 0)
for (int i = 0; i < attributeCount; i++)
reader.MoveToAttribute(i);
SetAttributeValue(newNode,
reader.Name, reader.Value);
// add new node to Parent Node or TreeView
if (parentNode != null)
parentNode.Nodes.Add(newNode);
else
treeView.Nodes.Add(newNode);
// making current node 'ParentNode' if its not empty
if (!isEmptyElement)
parentNode = newNode;
// moving up to in TreeView if end tag is encountered
else if (reader.NodeType == XmlNodeType.EndElement)
if (reader.Name == XmlNodeTag)
parentNode = parentNode.Parent;
else if (reader.NodeType == XmlNodeType.XmlDeclaration)
//Ignore Xml Declaration
else if (reader.NodeType == XmlNodeType.None)
return;
else if (reader.NodeType == XmlNodeType.Text)
parentNode.Nodes.Add(reader.Value);
finally
// enabling redrawing of treeview after all nodes are added
treeView.EndUpdate();
reader.Close();
/// <span class="code-SummaryComment"><summary>
/// Used by Deserialize method for setting properties of
/// TreeNode from xml node attributes
/// <span class="code-SummaryComment"></summary>
private static void SetAttributeValue(TreeNode node,
string propertyName, string value)
if (propertyName == XmlNodeTextAtt)
node.Text = value;
else if (propertyName == XmlNodeImageIndexAtt)
node.ImageIndex = int.Parse(value);
else if (propertyName == XmlNodeTagAtt)
node.Tag = value;
public static void SerializeTreeView(TreeView treeView, string fileName)
XmlTextWriter textWriter = new XmlTextWriter(fileName,
System.Text.Encoding.ASCII);
// writing the xml declaration tag
textWriter.WriteStartDocument();
//textWriter.WriteRaw("\r\n");
// writing the main tag that encloses all node tags
textWriter.WriteStartElement("TreeView");
// save the nodes, recursive method
SaveNodes(treeView.Nodes, textWriter);
textWriter.WriteEndElement();
textWriter.Close();
private static void SaveNodes(TreeNodeCollection nodesCollection,
XmlTextWriter textWriter)
for (int i = 0; i < nodesCollection.Count; i++)
TreeNode node = nodesCollection[i];
textWriter.WriteStartElement(XmlNodeTag);
textWriter.WriteAttributeString(XmlNodeTextAtt,
node.Text);
textWriter.WriteAttributeString(
XmlNodeImageIndexAtt, node.ImageIndex.ToString());
if (node.Tag != null)
textWriter.WriteAttributeString(XmlNodeTagAtt,
node.Tag.ToString());
// add other node properties to serialize here
if (node.Nodes.Count > 0)
SaveNodes(node.Nodes, textWriter);
textWriter.WriteEndElement();
And this is how i'm using the class this method i'm calling it inside the CreateDirectoryNode and i'm updating the treeView in real time when getting the ftp content from the server i build the treeView structure in real time.
DateTime last_update;
private void UpdateList(TreeNode tn_rt)
TimeSpan ts = DateTime.Now - last_update;
if (ts.TotalMilliseconds > 200)
last_update = DateTime.Now;
treeViewMS1.BeginUpdate();
treeViewMS1.Nodes.Clear();
treeViewMS1.Nodes.Add(tn_rt);
TreeViewXmlPopulation.SerializeTreeView(treeViewMS1, @"c:\XmlFile\Original.xml");
ExpandToLevel(treeViewMS1.Nodes, 1);
treeViewMS1.EndUpdate();
And when i'm running the program again in the constructor i'm doing:
if (File.Exists(@"c:\XmlFile\Original.xml"))
TreeViewXmlPopulation.DeserializeTreeView(treeViewMS1, @"c:\XmlFile\Original.xml");
My question is how can i update the xml file in real time like i'm doing now but also with the Tag property so next time i will run the program and will not get the content from the ftp i will know in the treeView what is file and what is directory.
The problem is that now if i will run the program the Tag property is null. I must get the ftp content from the server each time.
But i want that withoutout getting the ftp content from server to Tag each file as file in the treeView structure.
So what i need is somehow where i;m Tagging "file" or maybe when updating the treeView also to add something to the xml file so when i will run the progrma again and read back the xml file it will also Tag the files in the treeView.

How to retrieve data (xml file) using jsp

I am a newbie to xml. I have decided to store my information in the xml file. may I know how can I retrieve my information from the xml file?
Thanx in advance.

I am a newbie to xml. I have decided to store my
information in the xml file. may I know how can I
retrieve my information from the xml file?
Thanx in advance.You can get the information from the XML file using one of the parsers available, such as Xerces http://xml.apache.org, and JDOM as an API.
Using this you have the option of having a SAXParser or a DOMParser.
SAX (Simple API for XML) is an event based parser, so if you know the XML structure, and need to find a certain element, you can just look for the element name,and retrieve the value of the element, it's attributes and its children.
DOM(Document Object Model)represents the XML as a tree, but uses more resources as it stores the entire tree in memory. But it is good in that you can traverse the whole tree.
JDOM would be a good idea too. If you download this, you can use it's API, which is very good, that will use the parser on your system (Xerces). I would definately recommend JDOM.

How to update data in a xml file.

I am able to retrieve data from a xml file but not able to update data. Also how can i add or delete node from a xml file.

Hi,
For some time I have also been trying to do the same thing with no success. So far I have tried a few approaches like $.post functions $.ajax post functions and HTML5 fileWriter functions. I am not well aware of the web development techniques but as fas as I understand the post or update of the json file should be done on the serverside mainly because of security issues. I am not sure how appbuilder works entirely and if there is any way to do this.
Have you managed to find a solution ?
(P.S. my goal is to update my chart data which is of course json file. So the idea here is to get some values from the user input and update the json file values then refresh the chart and display it with the new values).
Best Regards,
A.Dyankov.

How to edit/update data into an XML file using Flex and Actionscript

I can read an external xml file, please see the code below:
protected function button1_clickHandler(event:MouseEvent):void
var GrowthChartsDataGrid:XML;
var loader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest("../GrowthChartsDataGrid.xml");
    loader.load(request);
    loader.addEventListener(Event.COMPLETE, onComplete)
function onComplete (event:Event)
     var loader:URLLoader = URLLoader(event.target);
     GrowthChartsDataGrid = new XML(loader.data);
     GrowthChartsDataGrid.GrowthChartGridView += <Month> {txtMonth.text} <Weight> {txtWeight.text} </Weight> </Month>
     texttesting.text = GrowthChartsDataGrid.toString();
I can read an XML file and can add an extra node and can display it in a text filed. But I want to update the XML file contents which will come from the txtMonth and txtWeight text boxes.
Please any suggestions???

First of all thanks for your quick reply .
I actually want to add another node inthe xml file. Files is at a local location and i can read the file and add an extra node (but I cant store this extra node in the actual XML file). But I want to save XML with the extra node.
For exmaple,
my current xml is:
<?xml version="1.0" encoding="utf-8"?>
<GrowthChartGridView>
    <Month> 1
    <Weight>3.5</Weight></Month>
<Month> 2
    <Weight>3.9</Weight></Month>
<Month> 3
    <Weight>4.5</Weight></Month>
</GrowthChartGridView>
and at run time, I can create a new node using the data from two textboxes at button click event.
     GrowthChartsDataGrid.GrowthChartGridView += <Month> {txtMonth.text} <Weight> {txtWeight.text} </Weight> </Month>
Now what I want to do is, I want to add this node back in to my XML. Therefore, the result I am looking for is, my local XML should update like this.
<?xml version="1.0" encoding="utf-8"?>
<GrowthChartGridView>
    <Month> 1
    <Weight>3.5</Weight></Month>
<Month> 2
    <Weight>3.9</Weight></Month>
<Month> 3
    <Weight>4.5</Weight></Month>
<Month> {txtMonth.text} <Weight> {txtWeight.text} </Weight> </Month> //I can read data from text boxes so its fine but I can not store this in to                                                                                                          my original XML
</GrowthChartGridView>
Thanks

How to display the data in XML files into JSP using Jdeveloper.

Hi All,
I have two XML files one XML file has the view names and the other has the table names of a particular views, how to display the data in JSP using JDeveloper where when i click a particular view the list of tables of that particular view from XML file two should be displayed in JSP Page.
Are there any reference documents, regarding the above process please can anyone guide through how to do it.

Let the servlet ask your business tier to provide the data, then stuff it into beans, and pack those into the Session instance. Then forward the request to the JSP, let the JSP get those beans and display them.

How to remove element namespaces in XML file using DOM or SAX?

Hi Guys,
I developed a JAVA mapping in XI to add name spaces for XML file, after mapping,name spaces xmlns="http://www.mro.com/mx/integration" and xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" were added correctly, but for some nodes, such as <Header> and <Content>, a name space xmlns="" was added automatically.Please check below files to compare.
It looks like be added automatically by XI. I didn't process anything for these nodes in JAVA program.
Now the issue is, how can I remove these redundant namespaces? Such as xmlns="".
Can I remove them using DOM or SAX in JAVA Mapping?
Thanks in advance.

Hi Milan,
Thanks for your replay.
Actually when I used module XMLAnonymizerBean to convert namespaces, the header of XML, such as <?xml version="1.0" encoding="UTF-8"?> was converted to format <?xml version='1.0' encoding='UTF-8'?>, quote was converted to single quote. Although I set parameter anonymizer.quote = ", it still didn't work, single quote appeared instead of quote.
I'm not sure why this happened. Can anyone help to clarify this?
Thanks

Manipulating XML file using flex 2.0

Hi,
how to add contents in to xml file using flex 2.0, ie i
actually wants to write data in to a xml file, so that data to be
appended at the end of the file.
Kumar

You can't! Well, at least Flex cannot do this. All Flex can
do is send this data -- any data -- to the server and it's up to
you how you want to append this data to a file on the server.
You see, flex can't write to local files. If you looking for
client side file manipulation, take a look at Flex's desktop
brother call AIR!

How to update XML file using XSLT

Hi there,
I have a "small" issue with exporting data to an XML file using XSLT.
A two steps process is needed to import data from a non-hierarchical XML file into ABAP, change the data, and then update the XML file with new values. The problem is not trivial, since the format of the XML file is a complex one: there are many interdependent elements on the same level, pointing to each other by using id and ref attributes. Based on these values the data can be read and written into an internal table. I use XSLT and XPath for that. So the inbound process is done and seems to work correctly. I have to mention that the file contains much more data than I need. I am working only with a small part of it.
Now the changed data must be exported back into the XML file, meaning that the content of certain elements must be updated. How can this be done with XSLT? I can pass only the internal table to the transformation, so how do I access the XML file in order to update it? I have tried to use the <B>xsl:document()</B> function to access the content of the file store locally on my PC, but it fails each time by throwing and URI exception. I have tried the absolute path without any addition and the path with the file:/// addition. Same result. Please advise.
Many thanks,
Ferenc
P.S. Please provide me with links only if they are relevant for this very matter. I will not give points for irrelevant postings...

XSLT approach: check these online tutorial
http://www.xml.com/pub/a/2000/08/02/xslt/index.html
http://www.xml.com/pub/a/2000/06/07/transforming/index.html
ABAP approach:
for example you have the xml (original) in a string called say xml_out .
data: l_xml type ref to cl_xml_document ,
        node type ref to if_ixml_node .
create object l_xml.
call method l_xml->parse_string
exporting
    stream = xml_out.
node = l_xml->find_node(
    name   = 'IDENTITY'
   ROOT   = ROOT
l_xml->set_attribute(
    name    = 'Name'
    value   = 'Charles'
    node    = node
(the above example reads the element IDENTITY and sets attribute name/value to the same)
like wise you can add new elements starting from IDENTITY using various methods available in class CL_XML_DOCUMENT
so how do I access the XML file in order to update it?
you have already read this XML into a ABAP variable right?
Sorry couldnt understand your whole process, why do you need to read local XML file?
