(PHP ActiveX) Find and Update an XML Attribute ValueSee more XML ExamplesDemonstrates how to find an element in XML with a specified attribute name and then update the attribute value.
<?php // Let's say you have 2 XML files with identical structures as shown directly below, // and you wish to update the values in the 1st XML file with those in the 2nd XML file. // <global> // <phrase id="2FADisabled" value="2factor authentication disabled"/> // <phrase id="2FAEnabled" value="2factor authentication enabled"/> // <phrase id="2FAResetFailed" value="Failed to disable two factor authentication"/> // </global> // <global> // <phrase id="2FAResetFailed" value="Failed to reset two factor authentication"/> // <phrase id="2FADisabled" value="2FA authentication disabled"/> // <phrase id="2FAEnabled" value="2FA authentication enabled"/> // </global> // First, initialize each of the Chilkat XML objects. // These could be loaded from files, but we'll just create them manually for this example.. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Xml') $xml1 = new COM("Chilkat.Xml"); $xml1->Tag = 'global'; $xml1->UpdateAttrAt('phrase',1,'id','2FADisabled'); $xml1->UpdateAttrAt('phrase',1,'value','2factor authentication disabled'); $xml1->UpdateAttrAt('phrase[1]',1,'id','2FAEnabled'); $xml1->UpdateAttrAt('phrase[1]',1,'value','2factor authentication enabled'); $xml1->UpdateAttrAt('phrase[2]',1,'id','2FAResetFailed'); $xml1->UpdateAttrAt('phrase[2]',1,'value','Failed to disable two factor authentication'); // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Xml') $xml2 = new COM("Chilkat.Xml"); $xml2->Tag = 'global'; $xml2->UpdateAttrAt('phrase',1,'id','2FAResetFailed'); $xml2->UpdateAttrAt('phrase',1,'value','Failed to reset two factor authentication'); $xml2->UpdateAttrAt('phrase[1]',1,'id','2FADisabled'); $xml2->UpdateAttrAt('phrase[1]',1,'value','2FA authentication disabled'); $xml2->UpdateAttrAt('phrase[2]',1,'id','2FAEnabled'); $xml2->UpdateAttrAt('phrase[2]',1,'value','2FA authentication enabled'); // Iterate over attribute values in xml2 and update the same in xml1. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder') $sbPath = new COM("Chilkat.StringBuilder"); $i = 0; $count_i = $xml2->NumChildrenHavingTag('phrase'); while ($i < $count_i) { $xml2->I = $i; $phrase_id = $xml2->chilkatPath('phrase[i]|(id)'); $phrase_value = $xml2->chilkatPath('phrase[i]|(value)'); // Notice how the UpdateAttrAt method's 1st argument is a Chilkat path -- which is an expression // to find the location of the XML element to be updated. // Here we create a path of the form "/A/tagName,attributeName,attributeValuePattern", which means // find the direct descendent of xml2 having tag=tagName, with an attribute=attributeName where the attribute value // matches the attributeValuePattern. If attributeValuePattern does not contain a "*", then it must match directly. // We'll build a Chilkat path such as "/A/phrase,id,2FADisabled" $sbPath->SetString('/A/phrase,id,'); $sbPath->Append($phrase_id); // This assumes the corresponding element exists in xml1. $xml1->UpdateAttrAt($sbPath->getAsString(),1,'value',$phrase_value); $i = $i + 1; } // Now see how xml1 has been updated.. print $xml1->getXml() . "\n"; // <global> // <phrase id="2FADisabled" value="2FA authentication disabled"/> // <phrase id="2FAEnabled" value="2FA authentication enabled"/> // <phrase id="2FAResetFailed" value="Failed to reset two factor authentication"/> // </global> ?> |
