phpquery

jquery for php

This is a simple wrapper over the xpath library that lets you make queries on an html page with the more friendly syntax of jquery., _(*1)

you can use it also to make queries with the xpath syntax, _(*2)

public functions

load_str($html_string);
query($query_string,$relative_path); // returns DOMNodeList or DOMElement
xpath($query_string,$relative_path); // returns DOMNodeList or DOMElement
j_to_x($query_string);
innerHTML(DOMElement); // returns string
outerHTML(DOMElement); //return string

where $relative_path is optional and represent a saved query performed earlier., _(*3)

usage

load_str($page);

$pq->query(...);


```
### example

`sample.html` file

```

``` phpquery test: ``` "; $page=file_get_contents('sample.html'); $pq=new PhpQuery; $pq->load_str($page); echo "

"; //return a list of 2 components var_dump($pq->query('.c1')); echo "

"; //return the first element var_dump($pq->query('.c1')[0]); echo "

"; //print the transormation fron jquery syntax //to xpath syntax echo $pq->j_to_x('.c1.c3'); echo $pq->j_to_x('#myid'); echo "

"; //return a list of 1 element //from xpath syntax var_dump($pq->xpath('//*[@id="myid"]')); echo "

"; //return the first element //from xpath syntax var_dump($pq->xpath('//*[@id="myid"]')[0]); echo '

'; var_dump($pq->innerHTML($pq->query('.Opin')[0])); echo '

'; var_dump($pq->outerHTML($pq->query('.dav-k')[0])); ?>

the output:, _(*6)
