XPath large file problem

[ac s. <ac_...@ho...>]

hi,

I am having trouble parsing a large file as it is in excess of 12Mb. If i 
use a small file like 500Kb then it works fine but if i use a large file the 
script dies saying memory limit exceeded.

I have also tried to increase this limit to 32Mb but the result is the same.

Any ideas how i can go about doing this.

Thanks and regards
A C Sandeep

redesign your system?  ;-) 

I've not tried using phpxpath with such a large file but because it reads the 
whole document in every time not only will it require lots of memory it's 
likely to be very slow too. And because php is stateless it has to do it for 
each request. Depending on the number of users your memory usage and response 
times could be enormous. It all sounds hugely inefficient to me. 

I would be thinking in terms of splitting the data up, perhaps storing it in 
an rdbms and using phpxpath as a front end.
