Well, firstly, "attribute value templates" are things you find in a
stylesheet, not in a source document. But let's assume you mean
"attribute values containing "{".
I would have thought the cleanest approach was
<xsl:template match="node() | @*">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="@*[contains(., '{')]">
<xsl:attribute name="{name()}">
<xsl:value-of select="......."/>
</xsl:attribute>
</xsl:template>

Hi all,
I'm generating XSL stylesheets using XSL. One thing I want to do is
modify all attribute value templates found in the source document. I
thought something like this would do the job:
<stylesheet version="1.0" xmlns="http://www.w3.org/1999/XSL/Transform";>
<template name="modify-attribute-value-templates">
Create replacement value
</template>
<template match="*">
<copy>
<for-each select="@*">
<copy>
<call-template name="modify-attribute-value-templates"/>
</copy>
</for-each>
<apply-templates/>
</copy>
</template>
</stylesheet>
But much to my chagrin I realized that<copy> already copies the value
if applied to attributes. A workaround could be a long choose element
like this:
<template match="*">
<copy>
<for-each select="@*">
<choose>
<when test="not(contains(string(),'{'))">
<copy/>
</when>
<when test="local-name()='att1'">
<attribute name="att1">
<call-template name="modify-attribute-value-templates"/>
</attribute>
</when>
<when test="local-name()='att2'">
<attribute name="att2">
<call-template name="modify-attribute-value-templates"/>
</attribute>
</when>
<!-- a ton of more attributes -->
<otherwise>
<message terminate="yes">
The attribute value template found in attribute
<value-of select="local-name()"/>
isn't handled by the stylesheet.
</message>
</otherwise>
</choose>
</for-each>
<apply-templates/>
</copy>
</template>
There might be an awful lot of attributes that have to be handled. If
I don't know what attributes are to be found in the source document,
then I I'll have to add another step to the process, creating the
above choose statement using another stylesheet.
I refuse to believe that something I thought would be done in three
lines turns out to require thousands of lines for case differentiation
and potentially an additional step in the process. Can anyone help?
