Parsing XML Node with href attribute
Hi,
I have the following XML that has to be parsed using JSP DOM. All fine except for one. The only problem that i have is when to parsing the Node with href attribute.
I am using the following method, and it returned with weird result
currNode.getAttributes() ====> the result is com.sun.org.apache.xerces.internal.dom.AttributeMap@111ae04
currNode.getNodeValue() ====> the result is null
currNode.TextNode ===> it returned *2*
Can anyone please let me know what did I miss here? What should I do to parse the href attribute into the jsp page?
The below is the xml.
<MovieList>
<Movie href="DarkKnight.xml">
<head>
<Title>Batman Dark Knight</Title>
<Genres>
<Genre>Action</Genre>
<Genre>Sci-Fi</Genre>
</Genres>
<Description>Movie Details here</Description>
</head>
</Movie>
</MovieList>Thanks
I am not sure what "JSP DOM" is exactly. In the W3C DOM supported since SUN Java 1.4 if you have an element node and want to access an attribute value you can simply use String href = movieElement.getAttribute("href"); You might need to cast your Node to Element first e.g.Element movieElement = (Element)currNode;

Using XSLT to extract value of a XML node with namespace
I have a XML source code here.

</item>
</channel>
</rss>
I want to use XSLT to extract value of a XML node with namespace <job:location>, and the returned value should be string 'Sydney - Inner Suburbs & CBD'. I tried a few XSL code below, but failed with error or nothing was returned.
<xsl:value-of select="job:location" disable-output-escaping="yes"/>
<xsl:value-of select="job/location" disable-output-escaping="yes"/>
<xsl:value-of select="job\location" disable-output-escaping="yes"/>
<xsl:value-of select="location" disable-output-escaping="yes"/>
This might be an easy question for you, but I would appreciate if anyone can help.Hi Suncorp IT Learner,
We need to tell the XSLT that some elements are in another namespace. Copy the xmls declarations for the prefixes you need to use. Then use the xsl format as:
<xsl: value-of select=”job:location/@PUReferenceID”/>
In following issue, Chriztian has a good explanation:

Add indent spaces to xml nodes with ms IXMLDOM
Hi All,
Currently I was update a xml file with IXMLDOM, after add nodes to xml file, we found the new added node was written in one line always. this make it hard to find the differences with merge tools.
and after we try to add text node to the xml to format it, it works unless we added nested nodes, it looks like:
<RootNode>
<ChildNodes>
<Child>value</Child></ChildNodes></RootNode>
Ugly, huh
And, when we set node's type with IXMLDOMNode::put_dataType it makes the node like:
<Name xmlns:dt="urn:schemas-microsoft-com:datatypes" dt:dt="string" Encoding="Standard" >Connections</Name>
but, the original nodes was:
<Name dt:dt="string" Encoding="Standard" xmlns:dt="urn:schemas-microsoft-com:datatypes">Connections</Name>
Also, it will not affect the its function, just cause extra efforts to merge the results.
So my questions:
1. is there any built-in functions that can be used to format the xml file to a indented version.
2. how to adjust the sequences of attributes of a node.
Thanks,
Levi
PS: currently, I was working on Windows CE 6.0, and these issues met on desktop OS too.
One world, one dream> 1. is there any built-in functions that can be used to format the xml file to a indented version.

How to count number of xml nodes , with JSTL XML api?
I am trying to count the number of nodes in the parsed xml by doing this:
<x:out select="count($doc/Items/Item)"/>
There are about 50 item nodes in the source xml, but I get the output as 0
Is this syntax correct?
I searched every where but couldn't find the xpath syntax to be used inside jstl xml tags, I was assuming that it's the same as the syntax used in xsltThank you for your reply, sorry I wasnt very clear with my question.
I want to count the number of nodes inside the jsp file , not inside the xslt file.
My xml file is something like this for example:
<?xml version="1.0" encoding="UTF-8"?>
<DocumentRootNode>
<Products>
<Item>1</Item>
<Item>2</Item>
<Item>3</Item>
<Products>
</DocumentRootNode>
I want the count of number of Item nodes , in the JSP file.
I'm doing something like this in the JSP but it gives 0 instead of 3:
<c:import url="source.xml" var="xml" charEncoding="UTF-8"/>
<x:parse doc="${xml}" var="xml_doc"/>
<x:out select="count($xml_doc/Products/Item)"/>

Hi,-
I am trying to parse an XML string with xpath as follows but I am getting null for getresult.
I am getting java.xml.xpath.xpathexpressionexception at line where
getresult = xpathexpression.evaluate(isource); is executed.
What should I do after
xpathexpression = xPath.compile("a/b");in the below snippet?
Thanks
String xmlstring ="..."; // a valid XML string;
Xpath xpath = XPathFactory.newInstance().newPath();
xpathexpression = xPath.compile("a/b");
// I guess the following line is not correct
InputSource isource = new inputSource(new ByteArrayInputStream(xmlstring.getBytes())); right
getresult = xpathexpression.evaluate(isource);My xml string is like:
<a>
<b>
<result> valid some more tags here
</result>
</b>
<c> 10
</c>
</a>Edited by: geoman on Dec 8, 2008 2:30 PMI've never used the version of evaluate that takes an InputSource. The difficulty with using it is that it does not save the DOM object. Each expression you evaluate will have to create the DOM object, use it once and then throw it away. I've yet to write a program that only needs one answer from an XML document. Usually, I use XPath to locate somewhere in a document and then read "nearby" content, add new content nearby, delete content, or move content. I'd suggest you may want to parse the XML stream and save the DOM Document.
Second, all of the XPath expressions search from a "context node". I have not had good luck searching from the Document object, so I always get the root element first. I think the expression should work if you use the root as the context node. You will need one of the versions of evaluate that uses an Object as the parameter. -

Any sample code how to parse this kind of xml file with namespaces...
Regards,
Purushothami have exactly the same problem with KXml2, but using a j2me-polish netbeans project.
i've tried to work around with similar ways like you, but none of them worked. now i've spent 3 days for solving this problem, i'm a bit disappointed :( what is wrong with setting the downloaded kxml2 jar path in libraries&resources?

Parsing XML file with different languages (Xerces)
How do we code or program to an XML file with different
languages , say english and spanish. WHen we parse such a document with the default locale , the presence of special characters throws errors .For eg when I use xerces and use
DOMParser parser = new DOMParser();
try
// Parse the XML Document
parser.parse(xmlFile);
catch (SAXException se)
se.printStackTrace();
org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0xfc) was found in the element content of the document.
System Error: void org.apache.xerces.framework.XMLParser.parse(org.xml.sax.InputSource)
So what locale do we set before we parse ?How to handle this problemYou need an encoding attribute in the xml declaration. If you don't, the parser assumes UTF-8, which are ASCII characters up to 127 - useful (only) for English.
So, something like this would allow you to use characters above 127, ISO-8859-1 is the encoding used by standard PCs.
<?xml version="1.0" encoding="ISO-8859-1"?>
You can find a (offical) list of encodings at:
http://www.iana.org/assignments/character-sets
I'm not sure about mixing various encodings. I think you have to resort external parsed entities, which can have their own encoding, but I think you cannot mix encodings in one XML file.
Good luck. -
Getting null value while parsing "XML String" with encoding WINDOWS-1252.

My "xml string" has the encoding vaule: WINDOWS-1252.
I am using the following code to convert the "xml string" to Document. I am getting the Document values as a "null" while converting the above "string xml"
String strXML = //my above string xml.
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
docBuilderFactory.setIgnoringElementContentWhitespace(true);
docBuilder = docBuilderFactory.newDocumentBuilder();
doc = docBuilder.parse(new InputSource(new StringReader(strXML)));
System.out.println("doc value.."+doc)//I am getting null value for "doc".

(without the rest of the code, i'm guessing that) most likely you are grabbing the first child node of the item element. however, you are not accounting for some text nodes that are most likely in that list, like the whitespace between the item element and the attribute element. please go read some tutorials on xml, there are thousands of them out there, and they will answer all you initial questions much more efficiently than posting each step to the forums. -
I would like to parse an xml document using xpath, see:
http://www.onjava.com/pub/a/onjava/2005/01/12/xpath.html
however, in the documentation (in the link above), it states that I need J2SE 5.0.
Currently, I have:
$ java -version
java version "1.5.0_11"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)
Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode, sharing)
Does that mean that I really have to install J2SE 5.0 in order to use J2SE 5.0's XPath support? Does anybody know anything about getting started with XPath, and whether I can just use my existing version of Java? I've never used XPath.
For more documentation, one can view:

How to parse XML document with default namespace with JDOM XPath
Hi All,
I am having difficulty parsing using Saxon and TagSoup parser on a namespace html document. The relevant content of this document are as follows:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<div id="container">
<div id="content">
<table class="sresults">
<tr>
<td>
<a href="http://www.abc.com/areas" title="Hollywood, CA">hollywood</a>
</td>
<td>
<a href="http://www.abc.com/areas" title="San Jose, CA">san jose</a>
</td>
<td>
<a href="http://www.abc.com/areas" title="San Francisco, CA">san francisco</a>
</td>
<td>
<a href="http://www.abc.com/areas" title="San Diego, CA">San diego</a>
</td>
</tr>
</body>
</html>
Below is the relevant code snippets illustrates how I have attempted to retrieve the contents (value of <a>):
import java.util.*;
import org.jdom.*;
import org.jdom.xpath.*;
import org.saxpath.*;
import org.ccil.cowan.tagsoup.Parser;
( 1 ) frInHtml = new FileReader("C:\\Tmp\\ABC.html");
( 2 ) brInHtml = new BufferedReader(frInHtml);
( 3 ) // SAXBuilder saxBuilder = new SAXBuilder("org.apache.xerces.parsers.SAXParser");
( 4 ) SAXBuilder saxBuilder = new SAXBuilder("org.ccil.cowan.tagsoup.Parser");
( 5 ) org.jdom.Document jdomDocument = saxbuilder.build(brInHtml);
( 6 ) XPath xpath = XPath.newInstance("/ns:html/ns:body/ns:div[@id='container']/ns:div[@id='content']/ns:table[@class='sresults']/ns:tr/ns:td/ns:a");
( 7 ) xpath.addNamespace("ns", "http://www.w3.org/1999/xhtml");
( 8 ) java.util.List list = (java.util.List) (xpath.selectNodes(jdomDocument));
( 9 ) Iterator iterator = list.iterator();
( 10 ) while (iterator.hasNext())
( 11 ) {
( 12 ) Object object = iterator.next();
( 13 ) // if (object instanceof Element)
( 14 ) // System.out.println(((Element)object).getTextNormalize());
( 15 ) if (object instanceof Content)
( 16 ) System.out.println(((Content)object).getValue());
.This program would work on the same document without the default namespace, hence, it would not be necessary to include ns prefix along in the XPath statements (line 6-7) either. Moreover, I was using org.apache.xerces.parsers.SAXParser to have successfully retrieve content of <a> from the same document without default namespace in the past.
I would like to achieve the following objectives if possible:
( i ) Exclude DTD and namespace in order to simplifying the parsing process. How this could be done?
( ii ) If this is not possible, how to include it in XPath statements (line 6-7) so that the value of <a> is picked up correctly?
( iii ) Would changing from org.apache.xerces.parsers.SAXParser to org.ccil.cowan.tagsoup.Parser make any difference as far as using XPath is concerned?
( iv ) Failing to exlude DTD, how to change the lookup of a PUBLIC DTD to a local SYSTEM one and include a local DTD for reference?
I am running JDK 1.6.0_06, Netbeans 6.1, JDOM 1.1, Saxon6-5-5, Tagsoup 1.2 on Windows XP platform.
Any assistance would be appreciated.
Thanks in advance,

<Sport sport_code="FOOT" name="Calcio" has_events="Y" disporder="-2"/>
<Sport sport_code="TENN" name="Tennis" has_events="Y" disporder="1"/>
<Sport sport_code="BASK" name="Basket" has_events="Y" disporder="2"/>
<Sport sport_code="VOLL" name="Pallavolo" has_events="Y" disporder="4"/>
<Sport sport_code="HAND" name="Pallamano" has_events="N" disporder="5"/>
<Sport sport_code="ICEH" name="Hockey su Ghiaccio" has_events="Y" disporder="6"/>
<Sport sport_code="AMFO" name="Football Americano" has_events="N" disporder="7"/>
<Sport sport_code="BASE" name="Baseball" has_events="Y" disporder="7"/>
</ContentAPI>
I want to use LINQ TO XML in order to read it into an object var.
This is the code that i wrote but i doesn't work...
XDocument xdoc = XDocument.Load(string.Format("myURL....."));
var Sport = from feed in xdoc.Descendants("Sport")
select new
_sport_code = feed.Attribute("sport_code").Value,
_name = feed.Attribute("name").Value,
_has_events = feed.Attribute("has_events").Value,
_disporder = feed.Attribute("disporder").Value
foreach (var s in Sport)
The program doesn't run inside the foreach loop...
for sure the problem is on the linq to xml query...
Thanks for your helpHello, I'm back again...
Now I have to parse a second file XML with some little differences on the track:
<ContentAPI xmlns="http://www.geneity.co.uk/genbet/ContentAPI" status="OK" timezone="UTC" msg_stamp="NzM1NTQ5MDQ6MTAyMTppdA==" version="1.0" request="get_classes_for_sport">
<Sport sport_code="FOOT" name="Calcio" disporder="-2">
<SBClass sb_class_id="12432" name="Italia" has_events="Y" disporder="-9999"/>
<SBClass sb_class_id="14603" name="Euro 2016" has_events="N" disporder="-1000"/>
</Sport>
</ContentAPI>
The C# code to get the SBClass elements is this:
XDocument xdoc = XDocument.Load(string.Format(url_Get_Region_By_Lang_Sport, pCodLang, pCodSport));
var SportRegion = from _SportRegion in xdoc.Descendants(XName.Get("Sport", "http://www.geneity.co.uk/genbet/ContentAPI")).Descendants("SBClass")
select new
CodSport = _SportRegion.Attribute("sport_code").Value.Trim(),
SbRegionId = _SportRegion.Attribute("name").Value.Trim(),
Region = _SportRegion.Attribute("has_events").Value.Trim(),
HasEvents = _SportRegion.Attribute("disporder").Value.Trim(),
RegionOrder = _SportRegion.Attribute("disporder").Value.Trim()
foreach(var sptr in SportRegion)
The program doesn't step inside the foreach loop...
Thanks again! -
How to select a specific XML node with XPath
Hi,
I'm trying to a select a specific node from my XML data using the XPath Builder. For example, say I have a process variable 'xmlData' with the
following contents:
User 1
101
User 2
102
I can successfully use the following expression to retrieve the name of
a specific user:
(/process_data/xmlData/users/user[userid='102'])/name
The problem is I need to use another process variable for the selection
key. For Example:
(/process_data/xmlData/users/user[userid=/process_data/@userId])/name
But this always returns null. I've tried surrounding /process_data/@userId
with single quotes, double quotes, and event {$..$}.
Any help would be greatly appreciated.
Thanks.Hi,
Thanks for the quick replies. I gave a bit of a bad example, as the
userid in my data is really a string, not a number.
A better example is:
User 1
user1
User 2
user2
I can get the following to work perfectly:
(/process_data/xmlData/users/user[userid='user2'])/name
but I can't get it to work with
/process_data/@userId = "user2"
(/process_data/xmlData/users/user[userid=/process_data/@userId])/name
Thanks. -
I trying to delete all the node from a XML that doesn't match some values.
<Data>
<Type id="1">
<Details id="1">
<Products id="1">
<Value>123</Value>
</Products>
</Details>
<Details id="2">
<Products id="2">
<Value>123</Value>
</Products>
</Details>
<Details id="1">
<Products id="3">
<Value>123</Value>
</Products>
</Details>
</tType>
<Type id="2">
<Details id="1">
<Products id="1">
<Value>123</Value>
</Products>
</Details>
<Details id="2">
<Products id="2">
<Value>123</Value>
</Products>
</Details>
</Type>
</Data>;
Let's suppose I want to delete all the nodes "Details" where id == 1.
I tried something like:
delete xml..Details.(@id == 1);
But this gives me and error...
TypeError: Error #1119: Delete operator is not supported with operand of type XMLList
So I tried:
= 1);
delete xml..Details.(@id == 1)[0];
But this produces the following result (what makes some sense, since I passed only index 0).
<Data>
<ClientType id="1">
<Details id="2">
<Products id="2">
<Value>123</Value>
</Products>
</Details>
<Details id="1">
<Products id="3">
<Value>123</Value>
</Products>
</Details>
</ClientType>
<ClientType id="2">
<Details id="1">
<Products id="1">
<Value>123</Value>
</Products>
</Details>
<Details id="3">
<Products id="2">
<Value>123</Value>
</Products>
</Details>
</ClientType>
</Data>
Only the first match is delete and not all the nodes.
Can someone help on this one?
thank you.Ok, I tried something and It works...
while(xml..Details.(@id == 1).length() > 0)
delete xml..Details.(@id == 1)[0];
But, there's any direct solution to this? Only with E4X? -
Applet parsing XML doc with schema
I'm trying to parse (org.apache.xerces.parsers.SAXParser) an xml document and validate it with a schema file. I'm having a little difficulty understanding how the schemaLocation (as specified in the xml file) is used by the parser. I'm trying to use a relative path....but what is it relative to???
In the xml file I specify the schemaLocation as...
xsi:schemaLocation="http://tempuri.org/DeviceDefinition.xsd ./Configuration/DeviceDefinition.xsd"
The directory structure I'm using is...
ProjectX/applet.jar
ProjectX/applet.html
ProjectX/Configuration/DeviceDefinition.xml
ProjextX/Configuration/DeviceDefinition.xsd
It's my understanding that when working with an applet the paths are a relative to the directory where the applet is installed - ProjectX in this case. Yet when I use the above defined schemaLocation I get the following error:
[Fatal Error] :0:0: File "file:///C:/Documents and Settings/dnelson/Desktop/Configuration/DeviceDefinition.xsd" not found.
It seem to be using my user.dir as a starting point for the relative path. Does anyone know why this happens???
What's the proper way to specify the schemaLocation??xerces hates spaces in uri. so try encoding the url or get rid of the spaces
