I think the solution (b) works perfectly in cases where we have normal xml node. What about if the a child xml node contains parent xml node recursively?
Taken the above case, what if Permissions node in turn contains the Roles ?
Since we cannot use ref attribute, how to refer the Roles node in the above xsd?
Thanks

As I said in this message[^], I think I was wrong about not being able to use ref attributes. I'm not sure what was going on in my head that day 
This schema validates your XML with libxml2 2.7.3 (which is a pretty recent release). I've put in the maxOccurs attribute of the sequence that contains the Permission element to enable multiple Permission elements in a Permissions element.
<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Roles">
<xs:complexType>
<xs:sequence>
<xs:element ref ="Role"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name ="Role">
<xs:complexType>
<xs:sequence>
<xs:element ref="Permissions"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name ="Permissions">
<xs:complexType>
<xs:sequence maxOccurs="unbounded">
<xs:element name ="Permission" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

Finally, I could create the desired xsd to valid the xml.
I truly appreciate your great help.
Thanks a lot.

Ok, that part is done then and has nothing to do with:

how can i do this ?
Again, if you don't understand how to use javascript in a browser then you need to be studying more beginner material on that subject until you do understand.
Also:
lostinxsl wrote: I am only able to display the javascript function on a webpage
Javascript that is correctly added to HTML will not be displayed in the browser. So again, you need to know how to write HTML/Javascript before you try to generate it with anything else like XSLT.

If I execute the following xslt I get the result given below.
I'm no mathematician but 100 times 2500.01 does not equal 250001.00000000003
I can find very little about this on the web and no suggested fixes or
solutions.
This is causing me a big problem as my entire architecture hangs around xslt.
Using VS2008 and have IE8 installed.
Can anyone help? Please?
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
<xsl:template match="/">
<res>
<xsl:value-of select="2500.01 * 100"/>
</res>
</xsl:template>
</xsl:stylesheet>
<?xml version="1.0" encoding="utf-8"?>
<res>250001.00000000003</res>

Not strictly an XSLT problem - it's more that IEEE754 floating-point isn't completely accurate, especially with things like .1 or .01, as they are irrational when expressed in binary.
For example - I just tried your example with both Python[^] and ghci[^] (a Haskell[^] REPL), and they gave the same answer as you got.

On another forum (I know naughty) I got this response:
Well XPath 1.0 uses double floating point numbers like JavaScript or
Java do too and with these there is limited precision, in particular
when there is no finite binary representation of a number.
With XSLT 1.0 you can use format-number to ensure you get a certain
number of decimal positions. Or you need to change to XPath 2.0 (as
implemented by Saxon 9) and use xs:decimal numbers instead of double
numbers.

Quite true - I wasn't aware of that function until you mentioned it 
contactowen wrote: Or you need to change to XPath 2.0 (as

Also true (in the commercial version of Saxon, anyway - I don't think the free one supports XML Schema datatypes) - I presumed that you would be using MSXML, in which case XPath 2.0 and XSLT 2.0 aren't really an option.

can any one please help me out to insert the another image in the form of base64
inside the aatribute
<>
I have a xml format like above and I want to inset the image in place of existing image .
Please help
|
|
|
|
|
Firstly you need to convert your image to base64 - I'll presume you know how to do this.
To insert the new value, you need to navigate to the relevant element using the XML DOM[^] API. Then (presuming you're using Microsoft's MSXML) you would use the IXMLDOMElement::setAttribute[^] method with a name of "image" and the value set to the base64 encoded image string.

Hi
I am writing a code generation app using xslt.
My purpose is to check if any two nodes of the same parent node, have the same attribute value.
If so I want to append a number sequence in the ouput code, so that there is no duplication.
For example
-------------
if xml file is like
<code>
<methods>
<method name="first">
<method name="first">
<method name="second">
<method name="third">
</methods></code>
I want the output to be
-------------
void first1() {}
void first2() {}
void second() {}
void third() {}
Note: there is no number sequence attached to function name if it is not duplicated.
How to write XSLT to achieve this?
Thank you
Fadi

You want to use the 'preceding-sibling' and 'following-sibling' axes, like this:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/">
<xsl:apply-templates select="//methods/method"/>
</xsl:template>
<xsl:template match="method">
<!-- index is set to an empty value if the current name is unique in
the current set of 'method' elements, or to the index of the
current method in the set of methods with the same name if the
name isn't unique -->
<xsl:variable name="index"><xsl:if test="count(preceding-sibling::*[@name=current()/@name]) + count(following-sibling::*[@name=current()/@name])>0"><xsl:value-of select="1+count(preceding-sibling::*[@name=current()/@name])"/></xsl:if></xsl:variable>
void <xsl:value-of select="concat(@name, $index)"/>() {}
</xsl:template>
</xsl:stylesheet>

Hi,
When trying to use insertbefore() method to insert a node from an xml file to other Xml file the node is getting deleted from the old Xml file...
Please help me regarding the same..

You need to import the node, XmlNode XmlDocument.ImportNode(XmlNode, bool), first.

All,
I am some what new to C# and XML as well.
I am having one interesting query,
I am having one XML based file one (first.xml). it ios having the Element\Attrbute like
((<text id="textID" Font="Roman" Style="Regular"> Sample </text>))
Other XML file (second.xml) is having the data like
((<PersonalInfo>
<First Name> Raja </FirstName>
</PersonalInfo>))
I simple want to replace Sample in File1.xml with Raja from File2.xml
Can this be possible and achiveable.

Hi Guys, wondering if you can help me again,
I need to write a stylesheet for a xml document, i need to convert it to a html table with a header, i can get the header working and get the table created but i can't get the xml put within the table.
the code is below do you any ideas, i thought this was quite a simple task but its turns out harder than i thought.
xml sample - there is more to the code but this is a example, with the report is the title and other info but that is not relevent as the arguments fields is what i need to put into a table
<report-item-definition>
<arguments>
<argument>
<name>xVar</name>
<type>Column</type>
<default>@IPRED</default>
<display-name>X Axis Variable</display-name>
<description>X Axis Variable</description>
<visible>FALSE</visible>
<filter-type>@ALL</filter-type>
</argument>
<argument>
</report-item-definition>
The table show look like the following
Name - Type - Default - Display Name - Description - Visible - Filter Type
At the moment my style sheet looks like this - but it does not seem to be working
<?xml version="1.0" ?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
<xsl:template match ="/">
<html>
<head>
<title>XML Stylesheet</title>
</head>
<body>
<h1 align="center"><b><xsl:value-of
select="report-item-definition/item-title" /></b></h1>
<xsl:apply-templates />
</body>
</html>
</xsl:template>
<xsl:template match="report-item-definition/arguments">
<table width="700" border="1" align="center" style="font-family:verdana
font-size:10pt">
<tr bgcolor = "#cccccc">
<td width="130" align="center"><b>Name</b></td>
<td align="center"><b>Type</b></td>
<td align="center"><b>Default</b></td>
<td align="center"><b>Display Name</b></td>
<td align="center"><b>Description</b></td>
<td align="center"><b>Visible</b></td>
<td align="center"><b>Filter Type</b></td>
</tr>
<xsl:for-each select="arguments/argument">
<tr>
<td><xsl:value-of select="name" /></td>
<!--<td><xsl:value-of select="type" /></td>
<td><xsl:value-of select="default" /></td>
<td><xsl:value-of select="display-name" /></td>
<td><xsl:value-of select="descriptions" /></td>
<td><xsl:value-of select="visible" /></td>
<td><xsl:value-of select="filter-type" /></td>-->
</tr>
</xsl:for-each>
</table>
</xsl:template>
</xsl:stylesheet>
|

Your xsl:for-each executes in the scope of the current node, arguments. However, your XPath expression was designed to match a child arguments node of a parent arguments node:
<xsl:for-each select="arguments/argument"> It should be:
<xsl:for-each select="argument"> since the argument node is a child of the arguments node.

This is how I'd tend to write it - differences are:
- I've used CSS, rather than inline styles - my preference
- I've used the thead element for the header
- I've split up the templates a bit more - if you had more than one report-item-definition in an XML file, that would be useful
 Also, it makes the context node more obvious, so you don't get issues like the one you had that George pointed out previously. - I've used <xsl:apply-templates select="argument"/> rather than <xsl:for-each select="..."> to output each row of the table. My feeling is that using apply-templates like this is probably better idiomatic XSL than using for-each
<?xml version="1.0" ?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
<xsl:template match ="/">
<html>
<style>
th { text-align: center }
thead { background-color: #cccccc }
h1 { text-align: center; font-weight: bold }
</style>
<head>
<title>XML Stylesheet</title>
</head>
<body>
<xsl:apply-templates select="report-item-definition"/>
</body>
</html>
</xsl:template>
<xsl:template match="report-item-definition">
<h1><xsl:value-of select="item-title" /></h1>
<xsl:apply-templates select="arguments"/>
</xsl:template>
<xsl:template match="arguments">
<table width="700" border="1" align="center" style="font-family:verdana font-size:10pt">
<thead>
<tr>
<th width="130"><b>Name</b></th>
<th><b>Type</b></th>
<th><b>Default</b></th>
<th><b>Display Name</b></th>
<th><b>Description</b></th>
<th><b>Visible</b></th>
<th><b>Filter Type</b></th>
</tr>
</thead>
<xsl:apply-templates select="argument"/>
</table>
</xsl:template>
<xsl:template match="argument">
<tr>
<td><xsl:value-of select="name" /></td>
<!--<td><xsl:value-of select="type" /></td>
<td><xsl:value-of select="default" /></td>
<td><xsl:value-of select="display-name" /></td>
<td><xsl:value-of select="descriptions" /></td>
<td><xsl:value-of select="visible" /></td>
<td><xsl:value-of select="filter-type" /></td>-->
</tr>
</xsl:template>
</xsl:stylesheet>

In one of our data XML files, we need to have attribute values preserve white space at the end.
For example :
<!-- without space -->
<MyTag MyAttribute="a value" />
<!-- with space -->
<MyTag MyAttribute="a value " />
Are two different attribute values.
I tried using the preserve white space attribute
pXMLDoc->preserveWhiteSpace = VARIANT_TRUE;
but that completely craps out the parsing of the file, for example, sometimes (well, always)
I get the wrong number of items in a node list (IXMLDOMNodeListPtr)
for example, in the following snippet, when preserveWhiteSpace is FALSE, the list count is 2 and when preserveWhiteSpace is TRUE, the list count if 5 (!)
<MESSAGE_LIST>
<MESSAGE Id="10" Type="Info">
<FRENCH>Message 10</FRENCH>
</MESSAGE>
<MESSAGE Id="11" Type="Info">
<FRENCH>Message 11</FRENCH>
</MESSAGE>
</MESSAGE_LIST>
Is there something I can do to MSXML to have the parsing behaviour that I want ? i.e. read significant spaces from an attribute value.
Thanks for any help, tips or hints.
Max.
