How to parse xml with multiple, changing namespaces?
- by sweenrace
I have the following xml that I'm trying to parse and get the Account Data from
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:SearchResults xmlns="http://www.intuit.com/sb/cdm/v2" xmlns:ns2="http://www.intuit.com/sb/cdm/qbo" xmlns:ns3="http://www.intuit.com/sb/cdm/qbopayroll/v1">
<ns2:CdmCollections xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Accounts">
<Account>
<Id idDomain="QBO">31</Id>
<SyncToken>0</SyncToken>
<MetaData>
<CreateTime>2010-02-16T18:03:50-08:00</CreateTime>
<LastUpdatedTime>2010-02-16T18:03:50-08:00</LastUpdatedTime>
</MetaData>
<Name>Accounts Payable</Name>
<Subtype>AccountsPayable</Subtype>
<CurrentBalance>34002.00</CurrentBalance>
</Account>
<Account>
<Id idDomain="QBO">36</Id>
<SyncToken>0</SyncToken>
<MetaData>
<CreateTime>2011-01-11T13:24:14-08:00</CreateTime>
<LastUpdatedTime>2011-01-11T13:24:14-08:00</LastUpdatedTime>
</MetaData><Name>Accounts Receivable (A/R)</Name>
<Subtype>AccountsReceivable</Subtype>
<CurrentBalance>1125.85</CurrentBalance>
</Account>
</ns2:CdmCollections>
<ns2:Count>10</ns2:Count>
<ns2:CurrentPage>1</ns2:CurrentPage>
</ns2:SearchResults>
The following code sometimes work such that the I can see that children tags and values of CdmCollections. However, it doesnt always work for the same query.
Looking at the raw xml I can see the namespaces change, e.g. sometimes ns2="http://www.intuit.com/sb/cdm/qbo" (works) and other times ns2 = "http://www.intuit.com/sb/cdm/v2" (doesnt work). I thought by using the namespaces array I could handle that issue but its not working. Any suggestions how I can fix this?
$account_xml = new SimpleXMLElement($account_query_response);
$namespaces = $account_xml->getNamespaces(true);
$account_xml->registerXPathNamespace('c', $namespaces["ns2"]);
$x = 0;
foreach($account_xml->xpath('//c:SearchResults') as $search) {
echo "<br>row " . $x;
$search->registerXPathNamespace('c', $namespaces["ns2"]);
var_dump($search->xpath('//c:CdmCollections'));
}
