How to parse this XML array?

[Booster77]

Hello everyone,

 

For an application I'm working on I'm connecting to a webservice which gives me an XML as response. I have no influence on how that XML is formatted and I am trying to figure out how to parse this result.

 

The XML I get back is (truncated because it's way too long):

 

<browse result="1" first="1" last="65" total="65">
<th>
<td label="dimension" hideforuser="false" type="String">fin.trs.line.dim2</td>
<td label="Outstanding" hideforuser="false" type="Value">fin.trs.line.openbasevaluesigned</td>
<td label="Factuurbedrag" hideforuser="false" type="Value">fin.trs.line.basevaluesigned</td>
<td label="Invoice Number" hideforuser="false" type="String">fin.trs.line.invnumber</td>
<td label="" hideforuser="false" type="String">fin.trs.head.code</td>
<td label="Pay date" hideforuser="false" type="Date">fin.trs.line.matchdate</td>
<td label="Vervaldatum" hideforuser="false" type="Date">fin.trs.line.datedue</td>
<td label="Datum" hideforuser="false" type="Date">fin.trs.head.date</td>
<td label="boektype" hideforuser="false" type="String">fin.trs.head.status</td>
<td label="paystatus" hideforuser="false" type="String">fin.trs.line.availableforpayruns</td>
</th>
<tr>
<td field="fin.trs.line.dim2" hideforuser="false" type="String">2001</td>
<td field="fin.trs.line.openbasevaluesigned" hideforuser="false" type="Value">-629.93</td>
<td field="fin.trs.line.basevaluesigned" hideforuser="false" type="Value">-629.93</td>
<td field="fin.trs.line.invnumber" hideforuser="false" type="String"/>
<td field="fin.trs.head.code" hideforuser="false" type="String">BEGINBALANS</td>
<td field="fin.trs.line.matchdate" hideforuser="false" type="Date"/>
<td field="fin.trs.line.datedue" hideforuser="false" type="Date" name="31/10/2011">20111031</td>
<td field="fin.trs.head.date" hideforuser="false" type="Date" name="01/10/2011">20111001</td>
<td field="fin.trs.head.status" hideforuser="false" type="String" name="Definitief">final</td>
<td field="fin.trs.line.availableforpayruns" hideforuser="false" type="String" name="Ja">true</td>
<key>
<office>NLA003802</office>
<code>BEGINBALANS</code>
<number>201100001</number>
<line>16</line>
</key>
</tr>
<tr>
<td field="fin.trs.line.dim2" hideforuser="false" type="String">2000</td>
<td field="fin.trs.line.openbasevaluesigned" hideforuser="false" type="Value">-3570.00</td>
<td field="fin.trs.line.basevaluesigned" hideforuser="false" type="Value">-3570.00</td>
<td field="fin.trs.line.invnumber" hideforuser="false" type="String"/>
<td field="fin.trs.head.code" hideforuser="false" type="String">BEGINBALANS</td>
<td field="fin.trs.line.matchdate" hideforuser="false" type="Date"/>
<td field="fin.trs.line.datedue" hideforuser="false" type="Date" name="31/10/2011">20111031</td>
<td field="fin.trs.head.date" hideforuser="false" type="Date" name="01/10/2011">20111001</td>
<td field="fin.trs.head.status" hideforuser="false" type="String" name="Definitief">final</td>
<td field="fin.trs.line.availableforpayruns" hideforuser="false" type="String" name="Ja">true</td>
<key>
<office>NLA003802</office>
<code>BEGINBALANS</code>
<number>201100001</number>
<line>17</line>
</key>
</tr>

After I've done simplexml_load_string($result->ProcessXmlStringResult) it turns into:

SimpleXMLElement Object ( [@attributes] => Array ( [result] => 1 [first] => 1 [last] => 65 [total] => 65 ) [th] => SimpleXMLElement Object ( [td] => Array ( [0] => fin.trs.line.dim2 [1] => fin.trs.line.openbasevaluesigned [2] => fin.trs.line.basevaluesigned [3] => fin.trs.line.invnumber [4] => fin.trs.head.code [5] => fin.trs.line.matchdate [6] => fin.trs.line.datedue [7] => fin.trs.head.date [8] => fin.trs.head.status [9] => fin.trs.line.availableforpayruns ) ) [tr] => Array ( [0] => SimpleXMLElement Object ( [td] => Array ( [0] => 2001 [1] => -629.93 [2] => -629.93 [3] => SimpleXMLElement Object ( [@attributes] => Array ( [field] => fin.trs.line.invnumber [hideforuser] => false [type] => String ) ) [4] => BEGINBALANS [5] => SimpleXMLElement Object ( [@attributes] => Array ( [field] => fin.trs.line.matchdate [hideforuser] => false [type] => Date ) ) [6] => 20111031 [7] => 20111001 [8] => final [9] => true ) [key] => SimpleXMLElement Object ( [office] => NLA003802 [code] => BEGINBALANS [number] => 201100001 [line] => 16 ) ) [1] => SimpleXMLElement Object ( [td] => Array ( [0] => 2000 [1] => -3570.00 [2] => -3570.00 [3] => SimpleXMLElement Object ( [@attributes] => Array ( [field] => fin.trs.line.invnumber [hideforuser] => false [type] => String ) ) [4] => BEGINBALANS [5] => SimpleXMLElement Object ( [@attributes] => Array ( [field] => fin.trs.line.matchdate [hideforuser] => false [type] => Date ) ) [6] => 20111031 [7] => 20111001 [8] => final [9] => true ) [key] =

I don't know the following things:

 

1. Am I doing a smart move by doing the simplexml_load_string in the first place? Or should I just 'parse' the XML I get in return? The XML is a little complicated to me because it makes use of the '<td field="name">value here</td> construct.

2. How do I get the field name and the corresponding value out of the XML or the array?

 

What I need is the names and values in the <td> elements under <tr> and the values under <key>

 

I've been looking for a way for 2 days now and I'm hoping very much you can help. If you can get me started that would be great.

 

Thank you so much in advance.

try

$xml = simplexml_load_string($str);
#echo '<pre>',print_r($xml, true),'</pre>';
foreach ($xml->tr as $tr) {
    echo "<h4>td</h4>";
    foreach ($tr->td as $td) {
        echo "{$td['field']} : $td<br>";
    }
    echo "<h4>key</h4>";
    echo "office: $tr->key->office<br>";
    echo "code: $tr->key->code<br>";
    echo "number: $tr->key->number<br>";
    echo "line: $tr->key->line<br>";
}

Hi Barand,

 

That was the solution! Thank you so much for making me understand!

The code I posted almost worked for the extract you provided (with the addition of </browse> at the end. I have since added {...} to fix the bug when printing the <key> values

$xml = simplexml_load_string($str);
#echo '<pre>',print_r($xml, true),'</pre>';
foreach ($xml->tr as $tr) {
    echo "<h4>td</h4>";
    foreach ($tr->td as $td) {
        echo "{$td['field']} : $td<br>";
    }
    echo "<h4>key</h4>";
    echo "office: {$tr->key->office}<br>";
    echo "code: {$tr->key->code}<br>";
    echo "number: {$tr->key->number}<br>";
    echo "line: {$tr->key->line}<br>";
}

It depends on how much pruning you did before posting. If the <browse> tag is embedded inside other tags you need to adjust to take the parent(s) into account, but I cannot to more without the full xml structure.

I get what you mean It worked right away tho. I'm very happy with this. Now I understand the way it's supposed to be done I can continue. Once again thank you very much!
