Change value in XML

[tobeyt23]

Need to change the value in an XML string tried the following but no luck, any suggestions?

$_xml_string = '<Order>
<EmbeddedDoc DocumentName="TestDoc" DocumentFormat="PDF">jdsahfdhflhfsdlfhdslhsdflsdfhflkdslkfsdhkfhskldhkl</EmbeddedDoc>
<EmbeddedDoc DocumentName="TestDoc1" DocumentFormat="PDF">jdsahfdhflhfsdlfhdslhsdflsdfhflkdslkfsdhkfhskldhkl</EmbeddedDoc>
</Order>';


foreach($_xml_string->Order->EmbeddedDoc as $document)
{
  $document ='##FILE_CONTENT##';
}

$_xml_string is not an object.

$_xml_string = '<Order>
        <EmbeddedDoc DocumentName="TestDoc" DocumentFormat="PDF">jdsahfdhflhfsdlfhdslhsdflsdfhflkdslkfsdhkfhskldhkl</EmbeddedDoc>
        <EmbeddedDoc DocumentName="TestDoc1" DocumentFormat="PDF">jdsahfdhflhfsdlfhdslhsdflsdfhflkdslkfsdhkfhskldhkl</EmbeddedDoc>
    </Order>';
    
$xml = simplexml_load_string($_xml_string);

foreach ($xml->xpath('//EmbeddedDoc') as $doc) {
    echo $doc . '<br>';
}

Yes, sorry I did do that $_xml_string =  simplexml_load_string($_xml_request_data,'SimpleXMLElement', LIBXML_PARSEHUGE); However still cant replace the value.

[tobeyt23]

The xml EmbeddedDoc contains base64 encoded document so I want to string that out before i save the string to DB.

[tobeyt23]

Any suggestions still cant seem to get the value to change?

Show your current code if you've changed it and it's still not working.

[tobeyt23]

$_xml_string = '<Order>

        <EmbeddedDoc DocumentName="TestDoc" DocumentFormat="PDF">jdsahfdhflhfsdlfhdslhsdflsdfhflkdslkfsdhkfhskldhkl</EmbeddedDoc>

        <EmbeddedDoc DocumentName="TestDoc1" DocumentFormat="PDF">jdsahfdhflhfsdlfhdslhsdflsdfhflkdslkfsdhkfhskldhkl</EmbeddedDoc>

    </Order>';


$xml = simplexml_load_string($_xml_string);


foreach ($xml->xpath('//EmbeddedDoc') as $doc) {

    $doc = '##FILE##';

}


print_r($xml);

$doc = '##FILE##';

 

You're only setting a local variable, not manipulating the xml using simplexml.

 

See an example of using simplexml to actually manipulate the xml: http://runnable.com/UnQMA-VaS1tAAABz/how-to-add-and-edit-elements-to-a-xml-using-simplexml-for-php

Still not working, what am I missing?

$_xml_string = '<Order>
<EmbeddedDoc DocumentName="TestDoc" DocumentFormat="PDF">jdsahfdhflhfsdlfhdslhsdflsdfhflkdslkfsdhkfhskldhkl</EmbeddedDoc>
<EmbeddedDoc DocumentName="TestDoc1" DocumentFormat="PDF">jdsahfdhflhfsdlfhdslhsdflsdfhflkdslkfsdhkfhskldhkl</EmbeddedDoc>
</Order>';

          $xml = new SimpleXMLElement($_xml_string);

          foreach ($xml->xpath('//EmbeddedDoc') as $doc) {
              $doc = '##FILE##';
          }

          $newxml = $xml->asXML();
          echo $newxml;

[tobeyt23]

Any help would be greatful, I am banging my head here!

[CroNiX]

In the loop, instead of:

$doc = '##FILE##';

Try

$doc[0] = '##FILE##';

And when you echo $newxml, use htmlspecialchars() so you see everything, like htmlspecialchars($newxml)

THANKS!

It also works if you change them individually

$xml = new SimpleXMLElement($_xml_string);

$xml->EmbeddedDoc[0] = '##FILE##'  ;
$xml->EmbeddedDoc[1] = '##FILE##'  ;

$newxml = $xml->asXML();
echo '<pre>' . htmlentities($newxml) . '<pre>';
