Read xml file from last entry

[vjayis]

hi

i have a xml file which has transaction details of the users.

I m inserting data using appendChild() from php.

While displaying i need to display the last 5 entry or single entry or the whole entries descending using php.

Is there anyway to read the xml file from the lastentry using php...


regards
vijay

XPath in SimpleXML: xpath()

XPath Tutorial

XPath is a convenient way to address XML nodes. if you’re familiar with the DOM (e.g. from using Javascript) this shouldn’t be too complicated.

thanks i ll gothrough it..

(you could also do a text search, but it would be more complicated to get the items…)

how can i do a text search using php..

@vjayis

$xmltxt = file_get_contents("test.xml");
// or whichever search function you need
$pos = strpos($xmltxt, $_date_);

the point is, you need some clever code (probably including RegEx) to get the items from that (the XML is treated as a string, not as XML)

thanks

and i had worked an search from an example

$filename='example.xml';
 
$data = simplexml_load_file($filename);
$op = $data->xpath('/entries/entry[time>1251802411]');
 
   foreach($op as $ops) {
    echo $ops->acno."-".$ops->time."<br />";
   }
 

which outputs

B900326-1251802455
B900326-1251802528
B900326-1251804653
B900326-1251866308
B900326-1251866501

in this how can i search two or more conditions for example.....

acno='B900326' & time>'125180241 1'

how to implement it

@vjayis
add another square bracket.

node[condition1][condition2]
