Call-time pass-by-reference deprecation errors

[<li...@jm...>]

hi, i use xpath all the time, but i'm a little new to php.
i'm using the latest version of php.xpath [2.1 (beta)], 
and whether i include() it or require() it, i get copious [well, ten] 
errors of the following sort:

> Warning: Call-time pass-by-reference has been deprecated - argument 
> passed by value; If you would like to pass it by reference, modify the 
> declaration of [runtime function name](). If you would like to enable

there was no INSTALL or README in the top level of the src directory; 
am i missing a step, or does this look like  php version-mismatch?

thanks in advance,

not seen this error, but line 163 is in a deprecated function. Do you get the 
same msg using the preferred appendData, which uses different parameters?

that's kinda the same question that sam blum asked me. the funny part 
is, i'm not /using/ any of the functions yet, all i did was a one-line 
test page that just require()'s the class.php file. i added the

"php_flag allow_call_time_pass_reference on"

directive to my .htacess file, which made the php compiler shut up 
about the deprecation warnings. possibly something should get added to 
the readme about, it's a bit disconcerting to see all those errors at 
first.

also, a short example php file showing basic php.xpath usage would be 
extremely helpful. the class documentation is nice, but not so helpful 
to a beginning user who doesn't necessarily know in advance what 
methods might be useful. i downloaded the pxpxmldb source to have 
something else to look at, but just a simple "here's a new xpath 
object, here's how we select a node and print it out, done." would go a 
long way. i'll try and write one and post it, maybe that could also be 
bundled with the download as a resource for new users.

Faqs and examples.

All in due time folks :o)  I'd like to see this stuff too, but we are trying
to spend the time on 2.2 which will hopefully bring us out of "beta", then
we can enhance speed and produce more FAQ and examples stuff.

I had much the same thoughts myself. Here's a simple sample I wrote, first 
evaluating the first occurrence, then doing the same thing using a specific 
attribute. You can remove the comment on the print_r to see what 
evaluate/match creates (easier to read as plain text rather than html).

thank you kindly! saved my life, aka. lots of time fiddling around to 
figure stuff out. much obliged. in answer to my own question, i made 
a concise five-step php.xpath "getting started" guide with a small 
working demo and src, visible at: 

	http://jm3.net/misc/php-xpath-quickstart/

with any luck this document could help other newbies just beginning to 
wet their feet with php.xpath.
