"/RawData/page/text[upper-case(.)='ABC']"

its throwing an exception "XsltContext is needed for this query because of an unknown function"

Hi,

I'm trying to get the text element which contains value 1.345%, I tried as below to get the results. but the nodeList count is 0. please correct to get the correct results

XmlNodeList nodeList = rawData.SelectNodes("/RawData/page/text[.=<![CDATA[1.345%]]>");

If the value is simple text or integer, its working fine with the below code.

XmlNodeList nodeList = rawData.SelectNodes("/RawData/page/text[.='corporation'");

Both examples are missing a right square backet. If your second example works though then that wouldn't be the cause. But you should still fix it.

Instead the problem is that you can't treat CDATA like that. At least googling suggests you can't.

I just forgot to put right square bracket. what to do, to make it work with the value "10.5%" instead "corporation". Thanks in advance

XmlNodeList nodeList = rawData.SelectNodes("/RawData/page/text[.='corporation']");

I found that the problem is not with "%". The values is having extra spaces as " 10.34%"

So the below expression is not working.
"/Data/page/content[.='10.34%']".

its working with the expression "/Data/page/content[.=' 10.34%']".
Please guide me to solve this issue. Thanks in advance

<Data>
<page>
<content>  10.34%</content>
</page>
</Data>

Sounds like you are trying to add range validation to a textbox, but I doubt you are working with XML/XSL. See the forum list to find the forum appropriate for your question. Or you can ask a question in the general "Quick Answers" forum.

You could have posted this in a C# forum, you can get an answer much quciker than here. Make sure you are in the right place before posting a question.

Try this:

try
{
   Int32 number = Int32.Parse(txtBoxId.Text);
   if(number <= 80)
   {
      //go ahead
   }
   else
   {
      //alert user they have entered a number greater than 80
   }
}
catch(Excemption e)
{
   throw new Excemption("Not a valid interger!");
}

That's a basic function you need, you can call this function on your desired textbox events e.g. on onkeypress.

Hope this helps,
Morgs

Hi, I am having a problem in displaying XML in HTML as shown below -

XML:-

HTML

<ABC>
 <DEF>
   <GHI>Heading</GHI>
   <P/> Hello, How are you? 
   <P/> I am a Developer. 
 </DEF>
</ABC>

XSLT:-

HTML

?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
  <html>
  <body>
  <h2>xml to html</h2>
  <table border="0">
    <xsl:for-each select="ABC/DEF">
    <tr>
      <td><xsl:value-of select="GHI" /></td><br/>
      <td><xsl:value-of select="." /></td>
    </tr>
    
    </xsl:for-each>
  </table>
  </body>
  </html>
</xsl:template>

</xsl:stylesheet>

OUTPUT -

Heading
HeadingHello, How are you?I am a Developer.

I want Heading to be in line 1 and then a line break and then comes paragraph. Also i want a space/line break between two paragraphs.

How to get following output instead -

Heading

Hello, How are you?
I am a Developer.

Thanks
Andyyy

Your HTML is faulty.

XML

<table>
  <xsl:for-each select="ABC/DEF">
      <tr><td><xsl:value-of select="GHI"/></td></tr>
      <xsl:for-each select="p">
          <tr><td>
              <xsl:value-of select="."/>
          </td></tr>
      </xsl:for-each>
  </xsl:for-each>
</table>

You're using columns (TD) instead of rows (tr).

Also, change your XML to:

XML

<GHI>Heading</GHI>
<p>Hello, How are you?</p>
<p>I am a Developer.</p>

Thanks for your reply.

I agree with you about HTML part.

But this part of your suggested code doesn't work as it doesn't display paragraphs -

HTML

<xsl:for-each select="p">
          <tr><td>
              <xsl:value-of select="."/>
          </td></tr>
      </xsl:for-each>

The problem is, i have received XML from third party and there are hundreds of XML that needs to be displayed on webpage and everywhere they have used

HTML

<p/> 
Paragraph 1
<p/> 
Paragraph 2

So should i ask the client to produce XML correctly or is there any work around to be able to display each paragraph in separate line.

Thanks

You need to identify the inline paragraph and break up the output based on this. I'm platying with the idea but am getting stuck around mixing up carriage returns and line feeds, grrr!

If you can get them to parse it correctly, great. Otherwise, try yours again with the right HTML code to see if it can work. I wasn't able to get it myself.

Have you tried something like this:

HTML

<xsl:template match="*|text()">
<xsl:value-of select="."/>
</xsl:template>

And then where you have this:

HTML

<xsl:for-each select="ABC/DEF">
    <tr>
      <td><xsl:value-of select="GHI" /></td><br/>
      <td><xsl:value-of select="." /></td>
    </tr>

replace the second

HTML

<td>

line:

HTML

<td><xsl:apply-templates/></td>

Edit: sorry, fixed the formatting

Thanks,

Just tried it but doesn't work -

Here is the html/javascript I am using to call xml and xsl - just incase there is some problem in script instead:-

HTML

<html>
<head>
<script type="text/javascript">
function loadXMLDoc(dname)
{
if (window.XMLHttpRequest)
  {
  xhttp=new XMLHttpRequest();
  }
else
  {
  xhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xhttp.open("GET",dname,false);
xhttp.send("");
return xhttp.responseXML;
}

function displayResult()
{
	
xml=loadXMLDoc("test.xml");

xsl=loadXMLDoc("test.xsl");
// code for IE
if (window.ActiveXObject)
  {
  ex=xml.transformNode(xsl);
  document.getElementById("example").innerHTML=ex;
  }
// code for Mozilla, Firefox, Opera, etc.
else if (document.implementation && document.implementation.createDocument)
  {
  xsltProcessor=new XSLTProcessor();
  xsltProcessor.importStylesheet(xsl);
  resultDocument = xsltProcessor.transformToFragment(xml,document);
  document.getElementById("example").appendChild(resultDocument);
  }
}
</script>
</head>
<body onLoad="displayResult()">
<div id="example" />

</body>
</html>

Thanks
