From what I've seen personally and heard as well, that should considerably streamline the flow of data: file -> XML parser Instead of: file -> lots of zvals for the strings in PHP taking up much more than the original 12 MB of data -> imploding all those strings into a single variable -> passing the data by copying into a variable (no reference shown in example) -> XML parser Then you don't have to bring a 12 megabyte datafile into PHP userland by creating an array for each line and then imploding those lines. I'd be interested to hear how much of a difference using domxml_open_file() would make. Hope it helps! -- mjh
