Hi Pieter,

Yeah, as you mentioned second template 
"match="//input[@value='go'][preceding-sibling::a[1][contains(img/@src,
'cancel')]]"
doesn't match any node in the input XML in .NET environment. 

Output(as expected) in MSXML:
<html><body><table><tbody><tr><td>
<input type="Submit" name="fr_onclick_5000000012501_fr_cands_1077;1083;"
value="Cancel"/>
</td></tr></tbody></table></body></html>

Ouput in .NET::
<html><body><table><tbody><tr><td>
<input type="submit" name="fr_onclick_5000000012501_fr_cands_1077;1083;"
value="go">
</input></td></tr></tbody></table></body></html>

Note (value) attribute of <input> node gets modified in the first case
But not in Second case. For clarity I have removed the attributes from
other node. 
My concern was to locate the position of Input node and modify its
attribute. And the problem was in the differnce in bahaviour of MSXML
and .NET XSL libraries for the same match patter.

Initially I thought position() was creatin problem. But now it seems
that this is not the case. Momemt I remove "//" from the match pattern,
both gives the same (correct) output. 
I'm bit confused. 

Thanks,
Animesh

Animesh, you mean the second template doesn't make a match in .NET,
right?

And, I would like to see what you get using MSXML vs. XslTransform (both
output). 
Could you please post that?

BTW, like David C. comments, you can reduce your xpaths to:

<xsl:template match="a[img[contains(@src,'cancel')]]" priority="1"/>
<xsl:template
match="input[@value='go'][preceding-sibling::a[1][contains(img/@src,'can
cel'
)]]">

Does that help?

Cheers,
<prs/>

Hi,

Yeah, I'm using XSLTransform class of .NET framework.

My inputXSL:
<xsl:template match="//a[img[contains(@src,'cancel')]]" priority="1"/>
	<xsl:template
match="input[@value='go'][preceding-sibling::a[position()=1][contains(im
g/@src,'cancel')]]">
		<xsl:copy>
			<xsl:apply-templates select="@*"/>
			<xsl:attribute
name="type">Submit</xsl:attribute>
			<xsl:attribute
name="value">Cancel</xsl:attribute>
			<xsl:apply-templates select="*|text()"/>
		</xsl:copy>
	</xsl:template>
<!--Default Copy template -->
	<xsl:template match="*|text()|@*">
		<xsl:copy>
			<xsl:apply-templates select="*|text()|@*"/>
		</xsl:copy>
	</xsl:template>

InputXML:
<?xml version="1.0"?>
<html><body>		
<table bgcolor="#336699" width="98%" border="0" cellpadding="2"
cellspacing="0" style="margin-top: 10px;"> <tbody><tr> <td align="right"
fr_option="dynamic" fr_cands="1077;1083;"> <a
href="http://10.0.3.214:8080";
onmouseover="" onmouseout=""> <img
src="http://myprod.concureworkplace.com/ewp/Images/entrycancel.gif";
alt="Cancel" border="0" title="Cancel"/> </a> <input type="submit"
name="fr_onclick_5000000012501_fr_cands_1077;1083;"
value="go"/>
</td></tr></tbody></table></body></html>

And the problem is that in .NET above template doesn't match. 

Thanks,
Animesh

Hi Animesh,

Do you use the XslTransform?

Then you say:
> When I remove position() from Xpath above, it works.

So what's the problem then? Just kidding, I guess you still have a
problem,
just send in some representative XML, your XSL, and what output you
need.
We'll be able to help you better.

I have found this MS-KB article, it may not apply to your expression,
cause
you're not using postion() as a function parameter, but still it may
well be
a (another) bug:
http://support.microsoft.com/default.aspx?scid=kb;en-us;324033

HTH,
<prs/>

Hi,

I'm not sure whether this problem belongs to this group or not. 
But I'm facing very peculiar problem in .Net (version 1.1) environment.

Following XSL works with MSXML4 but NOT with .Net XSL translator:

<xsl:template
match="//input[@value='go'][preceding-sibling::a[position()=1][contains(
img/@src,'cancel')]]">

<--Do Some operation>

</xsl:template>

When I remove position() from Xpath above, it works.
I'm unable to figure out the problem. If anyone knows the solution, do
let
me know.

Thanks,
Animesh
