XSLT: how to match attribute having a specific value?

[Gerald Aichholzer]

Hello NG,

I have an XHMTL-file and would like to replace attribute
values using XSLT. The XHTML-file contains the following
code:

<applet code="MyApplet/MyApplet.class"
archive="prog/MyApplet.jar"
width="100%"
height="99%">
<param name="image" value="MyAppletImage"/>
<param name="select" value="MyAppletSelect"/>
</applet>

I would like to replace MyAppletImage resp. MyAppletSelect
with the correspondg values.

I thought about using the identity transformation plus
a construct like the following (which does not work,
unfortunately):

<xsl:template match="@value='MyAppletImage'">
<xsl:attribute name="value">
<xsl:value-of select="$image"/>
</xsl:attribute>
</xsl:template>

The purpose is to replace only these two attributes and
otherwise leave the original file as it is.

Any help is appreciated.

Thanx in advance,
Gerald

match patterns have to have the syntax of an XPath expression that
selects a node set. That is a boolean valued expression. You want

<xsl:attribute name="value">
<xsl:value-of select="$image"/>

$image doesn't appear to be defined here so this must be a global
parameter or variable. That's OK so long as you are replacing all such
attributes by the same image value.

</xsl:attribute>
</xsl:template>

thank you for pointing this out - I should have known that.

<xsl:template match="@value[.='MyAppletImage']">

This solution works perfectly

$image doesn't appear to be defined here so this must be a global
parameter or variable. That's OK so long as you are replacing all such
attributes by the same image value.

$image is a global variable (xslaram). Ideally I would touch
only value-attributes of param-elements. How could I achieve
this?

<xsl:template match="@value[.='MyAppletImage' and ??='param'>


Thanx for your help,

<xsl:template match="@value[.='MyAppletImage' and ??='param'>

if your source is xml with html element noames in no-namespace

<xsl:template match="@value[.='MyAppletImage' and parent:aram]>

or if it is xhtml


<xsl:template match="@value[.='MyAppletImage' and parent::haram]>

where h is bound by
xmlns:h="http://www.w3.org/1999/xhtml"
either on this element or on the xsl:stylesheet element.

<xsl:template match="@value[.='MyAppletImage' and parent:aram]">
<xsl:template match="@value[.='MyAppletImage' and parent::haram]">

or perhaps more naturally (and probably handled more efficiently by your
processor)

<xsl:template match="param/@value[.='MyAppletImage']">
<xsl:template match="haram/@value[.='MyAppletImage']">
