XPath query for <?define something="something" ?>

[=?ISO-8859-1?Q?Pekka_J=E4rvinen?=]

Hi,

How I can find <?something ?stuff?

XML:
<Wix>
<?define UpgradeCode="{f oobar-quux-xyzzy}"?>
<?define Manufacturer="C ompany"?>
<!-- update this ALWAYS -->
<?define PackageCode="RE PLACE"?>
</Wix>

How to match that REPLACE with XPath? Or even better: find only define
and PackageCode
Doesn't work:
/Wix[processing-instruction('de fine[@PackageCode='R EPLACE']')]
/Wix[processing-instruction('de fine')/[@PackageCode='R EPLACE']/
@PackageCode]
/Wix[processing-instruction('de fine')/[@PackageCode='R EPLACE']]/
@PackageCode
/Wix[processing-instruction('de fine[@PackageCode='R EPLACE']')/]/
@PackageCode

Works:
/Wix[processing-instruction('de fine')[3]]

But PackageCode isn't necessary always third.

These do not work because the processing instruction data is simply a
string, there are no attributes, they just look like them. You have to
access the data by querying the PI's string value, so e.g.

//processing-instruction('de fine')[ . = 'PackageCode="R EPLACE"']

This would find all <?define PackageCode="RE PLACE"?nodes. To parse
the string value use functions like substring-before() and substring().

The stuff in the <?define ... ?is not an attribute. It's just some
text that looks like an attribute. You can match it as text:

processing-instruction("de fine")[. = 'PackageCode="R EPLACE"']
or
processing-instruction("de fine")[contains(., "REPLACE")]
