I need to show only the name of the sales order owner name, which are storing under <FL val="Sales Order Owner"> tag.

After getting the xml, I convert into an array and then try to access. My code is like:

foreach ($xml_sales->result->SalesOrders->row as $t) {
  foreach ($t->FL as $rr) {
    echo $rr."<br />";  
  }
}

Which is showing all FL values.

$items = $xpath->evaluate( '//FL[@val="Sales Order Owner"]' );
for ( $i = 0; $i < $items->length; $i++ ) {
 echo $items->item( $i )->textContent . '<br>';
}

Actually by this url, I am getting the xml file. But finally I got some warning like: Warning: DOMDocument::loadXML() [domdocument.loadxml]: Start tag expected, '<' not found in Entity, line: 1 in C:\xampp\htdocs\ibanquet\manager\user_list.php on line 34

All you need to do is just create DOMDocument object, load your xml, create DOMXpath object for your document and evaluate xpath expression:

$xml = file_get_contents( "https://crm.zoho.com/crm/private/xml/SalesOrders/getRecords?authtoken=XXX&scope=crmapi" );

$doc = new DOMDocument();
$doc->loadXML( $xml );

$xpath = new DOMXPath( $doc );
$items = $xpath->evaluate( '//FL[@val="Sales Order Owner"]' );
for ( $i = 0; $i < $items->length; $i++ ) {
    echo $items->item( $i )->textContent . '<br>';
}

It will output:

Adithya Buddhavarapu
Adithya Buddhavarapu
Adithya Buddhavarapu
Adithya Buddhavarapu

You best express that with an Xpath expression:

$owner = ($nodes = $xml_sales->xpath('//FL[@val = "Sales Order Owner"][1]')) 
         ? (string) $nodes[0] 
         : NULL;

This will give:

Adithya Buddhavarapu

in your case. If the element is not found it is NULL.

//FL[@val = "Sales Order Owner"][1]

This is the xpath expression. It reads:

Take any FL element of the document that has the val attribute with the value "Sales Order Owner" that is the first element ([1]).

If you need that per row, it works similar, just run the xpath per row. See SimpleXMLElement::xpath.
