List of the processing-instruction names in a file?

[Vincent Lefevre]

How can I get the list of the processing-instruction names in a file?

I tried the Muenchian method; it works on the element names for instance, but if I replace * by processing-instruction to use it on the processing-instructions, I get nothing.

Probably your starting code is wrong. The Muenchian method works nicely:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xslutput method="text"/>

<xsl:key name="kPI" match="processing-instruction"
use="name"/>

<xsl:template match="/">
<xsl:for-each
select="//processing-instruction
[generate-id
=
generate-id(key('kPI',
name)[1]
)
]">
<xsl:value-of select="concat(name, '&#xA;')"/>

</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

when applied on this source.xml:

<t>
<?xxx PI1?>
<a>
<?xxx PI2?>
<b>
<?yyy PI3?>
<c/>
</b>
<?zzz PI4?>
</a>
</t>

the wanted result is produced:

xxx
yyy
zzz

I'm quite sure it was correct.

The Muenchian method works nicely:

I've tried your example, and I get nothing with xsltproc (with the tests I've done yesterday, it seems that PIs are not matched in xsl:key). I'm going to fill a bug report.

Yes, it is a bug -- I get "Transformation failed" with no more specific error message. My libXslt is at least 3 months old.

How can I get the list of the processing-instruction names in a file?

$ tr '\012\074' '\040\012' <foo.xml | grep '^?' | awk '{print substr($1,2)}'

I forgot to say that I needed that in XSLT (but then, the problem was a bug in libxslt).

$ tr '\012\074' '\040\012' <foo.xml | grep '^?' | awk '{print substr($1,2)}'

which doesn't work anyway.
