XPath_attribute
Hello,
I have encountered a problem that the xpath_query dose NOT take the
attribute with LETTERS but takes ONLY NUMBERS.
Is this a bug? Is there any way to get arround it? Thanks for help.
For example:
-------------- Following does NOT work ---------------
<?xml version="1.0"?>
<product id="AB123456">
<description> test </description>
</product>
>xindice xpath_query -c /../.. -q "/product[@id="AB123456"]"
----------------------------------------------------------
-------------- Following (control) works ---------------
<?xml version="1.0"?>
<product id="123456">
<description> test </description>
</product>
>xindice xpath_query -c /../.. -q "/product[@id="123456"]"
------------------------------------------------------------

Hi Jeff,
I am sorry for the confusion. In the email, I did forget to type the double
quotes around the 123456. In the real query, they are there (123456).
The testing result on Linux should be like this:
Following NOT Work Following Works
---------------------- --------------------------
-q //*[@id=123456] -q //product[@id=123456]
-q '//*[@id=123456]' -q '//product[@id=123456]'
-q "//*[@id=123456]" -q "//product[@id=123456]"
Still, the -q '//*[@id=123456]' does NOT work.
Thanks for your explanation of the quote issue on different platforms.
Charles

You've forgotten to quote the value of @id --- should be @id="123456" or
@id='123456'. I'm surprised any of the queries worked if they are
transcribed correctly below.
On Linux, '*' needs to be inside single quotes to prevent interpretation as
a file wildcard by the shell. On Windows (using the Windows command prompt)
/ needs to be inside double quotes to prevent interpretation as a command
switch. So on Linux, single quotes are needed on the outside of the query,
with double quotes on the inner values (e.g. attribute values). On Windows,
it needs to be the other way around.

Hi Mark
The single quotes do work on Linux. Thanks for you suggestion.
Still, both single and double quotes have failed on Windows.
By the way, do you or anyone else have any idea that why the * does not work
on Linux, which is independent of the quote issue?
Following NOT Work Following Works
---------------------- --------------------------
-q //*[@id=123456] -q //product[@id=123456]
-q '//*[@id=123456]' -q '//product[@id=123456]'
-q "//*[@id=123456]" -q "//product[@id=123456]"
This is an important query for retrieving selected element(s). I need help
badly.
Charles
