SimpleXML解析到数组

Question

I've got this XML Snippet.

It is being iterated using this foreach:

foreach($ProcurementPartNodes as $node) {
    $uniqueseq++;
    $linenum  = (string)$node->children("bms",true)->ProcurementRefLineNum;
    $resp["ProcurementRefLineNum"] = $linenum;
    $selected = $BuildSelectedPart($node, $linenum, $uniqueseq);
    $resp["SelectedPart"] = $selected;
    $resp["NeedByDateTime"] = "0001-01-01T00:00:00";
    $response_data["ProcurementPart"][] = $resp;
}

And each I'm trying to get each SelectedNode info using these functions:

function BuildSelectedPart($node, $procurementInfoUUID, $linenum, $uniqueseq) {
    $partdesc      = (string)$node[0]->children("bms", true)->PartDesc;
    $qty           = (int)$node[0]->children("bms", true)->Quantity;
    $unitlistprice = (string)$node[0]->children("bms",true)->PriceInfo->UnitListPrice;
    $unitnetprice  = (string)$node[0]->children("bms",true)->PriceInfo->UnitNetPrice;
    unset($selected);
    $selected["BMSObject"] = $BuildSelectedBMS($procurementInfoUUID);
    $selected["UniqueSequenceNum"] = $uniqueseq;      // Iterator for SelectedPart count
    // Iterate over the PartNumInfo nodes
    $partnumInfoNodes = $node[0]->xpath("//*[bms:ProcurementRefLineNum = ".$linenum."]/bms:SelectedPart/bms:PartNumInfo");
    foreach($partnumInfoNodes as $pnodes) {
        echo $pnodes->asXML();
        foreach($pnodes as $p) {
            $pnum = array(
                "PartNumType"=>(string)$p->children("bms",true)->PartNumInfo->PartNumType,// Can be OE, HollanderInterchange, or Stock
                "PartNum"=>(string)$p->children("bms",true)->PartNumInfo->PartNum         // Corresponding number of above type
            ); // PartNumInfo
        }
        $selected["PartNumInfo"][] = $pnum;
    }
    $selected["PartType"] = "PAL";                    // Usually PAL
    $selected["PartDesc"] = $partdesc;                // Description of Part Requested
    $selected["Quantity"] = $qty;                     // Quantity Requested
    $selected["PriceInfo"] = array(
            "UnitListPrice"=>$unitlistprice,          // Price Requested
            "UnitNetPrice"=>$unitnetprice             // Price Requested
        ); // PriceInfo                        
    return $selected;        
} // function BuildSelectedPart()

function BuildSelectedBMS($procurementInfoUUID) {
    $UUID = $this->CreateGuid("",true); // creates a new Guid value
    return array(
            "UUID"=>$UUID,                            // Generated UUID
            "RefUUID"=>$procurementInfoUUID           // ProcurementInfo.BMSObject UUID value from above
       ); // BMSObject        
}

This is what is expected, I don't seem to be getting the values from the PartNum and PriceInfo sections correctly. Been slapping my head around this for about an hour now...

Answer 1

For your part number data, change that bit to...

foreach($partnumInfoNodes as $pnodes) {
    $pnum = array(
        "PartNumType"=>(string)$pnodes->children("bms",true)->PartNumType,// Can be OE, HollanderInterchange, or Stock
        "PartNum"=>(string)$pnodes->children("bms",true)->PartNum         // Corresponding number of above type
    ); // PartNumInfo
    $selected["PartNumInfo"][] = $pnum;
}

You were trying to go another level down and you didn't need to.

I also think that your first set of data needs an extra level <SelectedPart>...

$partdesc      = (string)$node[0]->children("bms", true)->SelectedPart->PartDesc;
$qty           = (int)$node[0]->children("bms", true)->SelectedPart->Quantity;
$unitlistprice = (string)$node[0]->children("bms",true)->SelectedPart->PriceInfo->UnitListPrice;
$unitnetprice  = (string)$node[0]->children("bms",true)->SelectedPart->PriceInfo->UnitNetPrice;
