Need Help Removing Certain Elements From Array

[savagenoob]

I used DOM to parse data from html, then I made the data go into an array. the array now looks like Array([0]->street[1]->city, st, zip[2]->phone[3]->fax) and it is quite a long array. The problem is that when there is no fax number on the html, it doesnt show the fax on the array, so when I am trying to loop through this in a table it is throwing off my cells. Is there a way to delete all entries in an array that include Fax:* ? Is there a way to exclude all nodes that have Fax* using DOM? My current DOM looks like...

$address = $xpath->query('//td[@id="addressText"]');

Yes no maybe so?

It would be more efficient to change your processing code to simply skip the fax elements. But, yes, you can remove the fax elements first. It would be helpful to see the relevant code you have now to see what would be the best way to implement though.

Well I posted the xpath code I used to get the data from the <td> elements with id addressText, the address, phone number, and fax number reside in these tags.

Still havent figured out how to remove all "Fax:xxxxxxx" entries from my array or modify my xpath code to skip all <td> elements that contain "Fax:xxxxxxx". Any suggestions?

Here is the entire code:

$
$dom = new domDocument; 

    /*** load the html into the object ***/ 
    $dom->loadHTML($html); 

    /*** discard white space ***/ 
    $dom->preserveWhiteSpace = false; 

$xpath = new DOMXPath($dom); 

$tags = $xpath->query('//div[@id="large_green"]'); 
$address = $xpath->query('//td[@id="addressText"]'); 
$result = array(); 
$agency = array();
foreach ($address as $tag)
{

$result[] = trim($tag->nodeValue) . "<br>"; 
} 
foreach ($tags as $tag)
{

$agency[] = trim($tag->nodeValue) . "<br>"; 
} 

array_shift($agency);

for ($i = 0, $e = 0; $i < count($result); $i += 4, ++$e) {
$comagency = strip_tags($agency[$e]);
$comaddress = strip_tags($result[$i]) . " " . strip_tags($result[$i+1]);
$comphone = strip_tags($result[$i+2]);
?>

<tr>
<td><?php echo $comagency;?></td><td><?php echo $comaddress;?></td><td><?php echo $comphone;?></td><td></td><td align="center"><input type="checkbox" name="agencyadd[]" value="<?php echo $comagency . " Address:" . $comaddress;?>"/></td>
</tr>
<?php
}

Well, now that you have posted the code I can help you.

 

It *looks* like you are referencing data by it's position in the results returned. That's kind of a poor implementation and can easily break depending on how the input changes.

 

This logic should work, but you might need to modify the actual text being compared. I can't be sure since I can't see the input data.

foreach ($address as $tag)
{
    //If $tag->nodeValue contains the string "Fax:", skip this entry
    if(strpos($tag->nodeValue, "Fax:")===false) { continue; }
    $result[] = trim($tag->nodeValue) . "<br>"; 
}

Hm, can I put a wildcard after Fax: ? It will list the fax number after Fax: and I believe this is explicitly looking for "Fax:" not "Fax: (111) 111-1111"

. . . I believe this is explicitly looking for "Fax:" not "Fax: (111) 111-1111"

 

You believe wrong. If I was doing a check for a value exactly matching "Fax:" I would have done something like

if($tag->nodeValue == "Fax:") { continue; }

 

But, I used the function strpos() which

Returns the numeric position of the first occurrence of needle in the haystack string.

Oh sweet, thanks bud.
