Parse XML that Contains CDATA XML

PHP
6

Quick question are you trying to conjoin two documents into one to parse it all on one parse as the content document is a separate one? They can be merged, and your code works fine for that as this is your example isolated.


$xml = <<<XML
<?xml version="1.0" encoding="utf-8"?>
<webRequest>
    <id>160810</id>
    <request>
        <merchantShortName>ReServe</merchantShortName>
        <serviceName>reservationManagementServices</serviceName>
        <actionName>diningResListGet</actionName>
    </request>
    <authentication>
        <username>lynn</username>
        <password>lynn</password>
    </authentication>
    <content>
    <![CDATA[<?xml version="1.0" encoding="UTF-8" ?>
        <diningResListGetRequest>
            <dateRangeFilter>
                <fromDate>2015-10-15</fromDate>
                <toDate>2015-10-15</toDate>
            </dateRangeFilter>
            <siteNameFilter>
                <matchCriterion>EqualTo</matchCriterion>
                <stringValue>Frontier Vineyards</stringValue>
            </siteNameFilter>
            <maxReturned>50</maxReturned>
            <servicePeriodFilter>Dinner</servicePeriodFilter>
            <modifiedDateTimeFilter>
                <fromDateTime>2012-04-01T12:00:00</fromDateTime>
            </modifiedDateTimeFilter>
        </diningResListGetRequest>
    ]]></content>
</webRequest>
XML;



$rawXML = str_replace('<![CDATA[<?xml version="1.0" encoding="UTF-8" ?>', "", $xml);
$rawXML = str_replace(']]>', "", $rawXML);
$xml = simplexml_load_string($rawXML);

echo( $xml->saveXML() );

If I add a line space at the start of the xml I get the same error “simplexml_load_string(): Entity: line 2: parser error : XML declaration allowed only at the” so it may be work trimming the xml.
