标签： php xml domdocument

我试图用DOMDocument用PHP中的XML部分生成一些XML，并且我需要附加两个XML部分。

我有两个以名称分隔的XML部分。一个用于带数据的“信封”，另一个用于循环数据，我需要将它们放在一起。将循环的数据放入信封。

我已经从StackOverflow尝试了很多示例，但是它们没有提到如何使用名称空间。

让我们看一些示例：

第一部分：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:aut="http://www.domain.xy/OSB/Authentication/" 
    xmlns:sch="http://www.domain.xy/schedule/ScheduleManager/" 
    xmlns:urn="urn:entsoe.eu:edi:ess:schedulemessage:3:3">
    <soapenv:Header>
        <aut:mekAuth>
            <username>username</username>
            <password>p455w0rd</password>
        </aut:mekAuth>
    </soapenv:Header>
    <soapenv:Body>
        <sch:receiveScheduleRequest>
            <urn:ScheduleMessage DtdVersion="3" DtdRelease="3">
                <urn:MessageIdentification v="xyz"/>
                <urn:MessageVersion v="34"/>
                <urn:MessageType v="xyz"/>
                <urn:ProcessType v="xyz"/>
                <urn:ScheduleClassificationType v="xyz"/>
                <urn:SenderIdentification v="xyz" codingScheme="xyz"/>
                <urn:SenderRole v="xyz"/>
                <urn:ReceiverIdentification v="xyz" codingScheme="xyz"/>
                <urn:ReceiverRole v="xyz"/>
                <urn:MessageDateTime v="2019-06-23T23:23:28Z"/>
                <urn:ScheduleTimeInterval v="2019-06-22T22:00Z/2019-06-23T22:00Z"/>


                /* PART 2 WILL GOES HERE */


            </urn:ScheduleMessage>
        </sch:receiveScheduleRequest>
    </soapenv:Body>
</soapenv:Envelope>

第二部分：


                <urn:ScheduleTimeSeries>
                    <urn:SendersTimeSeriesIdentification v="xyz"/>
                    <urn:SendersTimeSeriesVersion v="34"/>
                    <urn:BusinessType v="xyz"/>
                    <urn:Product v="xyz"/>
                    <urn:ObjectAggregation v="xyz"/>
                    <urn:InArea v="xyz" codingScheme="xyz"/>
                    <urn:MeteringPointIdentification v="xyz codingScheme="xyz"/>
                    <urn:InParty v="xyz" codingScheme="xyz"/>
                    <urn:MeasurementUnit v="KWT"/>

                    /* PART 3 WILL GOES HERE */

                </urn:ScheduleTimeSeries>

第三部分：

                    <urn:Period>
                        <urn:TimeInterval v="2019-06-22T22:00Z/2019-06-23T22:00Z"/>
                        <urn:Resolution v="PT15M"/>
                        <urn:Interval  >
                            <urn:Pos v="1"/>
                            <urn:Qty v="0"/>
                        </urn:Interval>
                        <urn:Interval  >
                            <urn:Pos v="2"/>
                            <urn:Qty v="0"/>
                        </urn:Interval>
                        <urn:Interval  >
                            <urn:Pos v="3"/>
                            <urn:Qty v="0"/>
                        </urn:Interval>
                        <urn:Interval  >
                            <urn:Pos v="4"/>
                            <urn:Qty v="0"/>
                        </urn:Interval>
                    </urn:Period>

我需要这样做：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:aut="http://www.domain.xy/OSB/Authentication/" 
    xmlns:sch="http://www.domain.xy/schedule/ScheduleManager/"

        </aut:mekAuth>
    </soapenv:Header>
    <soapenv:Body>
        <sch:receiveScheduleRequest>
            <urn:ScheduleMessage DtdVersion="3" DtdRelease="3">
                <urn:MessageIdentification v="xyz"/>
                <urn:MessageVersion v="34"/>
                <urn:MessageType v="xyz"/>
                <urn:ProcessType v="xyz"/>

                <urn:ScheduleTimeInterval v="2019-06-22T22:00Z/2019-06-23T22:00Z"/>


                <urn:ScheduleTimeSeries>
                    <urn:SendersTimeSeriesIdentification v="xyz"/>
                    <urn:SendersTimeSeriesVersion v="34"/>
                    <urn:BusinessType v="xyz"/>
                    <urn:Product v="xyz"/>
                    <urn:ObjectAggregation v="xyz"/>
                    <urn:InArea v="xyz" codingScheme="xyz"/>
                    <urn:MeteringPointIdentification v="xyz" codingScheme="xyz"/>
                    <urn:InParty v="xyz" codingScheme="xyz"/>
                    <urn:MeasurementUnit v="KWT"/>

                     <urn:Period>
                        <urn:TimeInterval v="2019-06-22T22:00Z/2019-06-23T22:00Z"/>
                        <urn:Resolution v="PT15M"/>
                        <urn:Interval  >
                            <urn:Pos v="1"/>
                            <urn:Qty v="0"/>
                        </urn:Interval>
                        <urn:Interval  >
                            <urn:Pos v="2"/>
                            <urn:Qty v="0"/>
                        </urn:Interval>
                        <urn:Interval  >
                            <urn:Pos v="3"/>
                            <urn:Qty v="0"/>
                        </urn:Interval>
                        <urn:Interval  >
                            <urn:Pos v="4"/>
                            <urn:Qty v="0"/>
                        </urn:Interval>                 
                     </urn:Period>

                </urn:ScheduleTimeSeries>


            </urn:ScheduleMessage>
        </sch:receiveScheduleRequest>
    </soapenv:Body>
</soapenv:Envelope>

我的位置是这样的：

    public function generate_positions( $data, $res = "daily" )
    {
            $dom = new DOMDocument('1.0', 'UTF-8');
            $dom->xmlStandalone = true;
            $dom->formatOutput = true;

            $period = $dom->createElement("urn:Period");
            $period = $dom->appendChild( $period );

            $timeInterval = $dom->createElement("urn:TimeInterval");
            // $timeInterval->setAttribute("v", $data->interval);
            $timeInterval = $period->appendChild( $timeInterval );

            $resolution = $dom->createElement("urn:Resolution");
            $resolution->setAttribute("v", $time_resolution[$res]);
            $resolution = $period->appendChild( $resolution );

            foreach ( $data as $key => $value )
            {
                $interval = $dom->createElement("urn:Interval");
                $interval = $period->appendChild( $interval );

                $pos = $dom->createElement("urn:Pos");
                $pos->setAttribute("v", $value["pos"]);
                $pos = $interval->appendChild($pos);

                $qty = $dom->createElement("urn:Qty");
                $qty->setAttribute("v", $value["value"]);
                $qty = $interval->appendChild($qty);
            }

            return $dom->saveXML( $period );
    }

我想编写第二部分的generate函数，例如 generate_positions（） 函数，但是我不知道如何从中“粘贴”返回的xml generate_positions

我尝试使用appendXML（$ inner_xml），但通常收到以下错误消息：

消息：DOMDocumentFragment :: appendXML（）：名称空间错误：未定义Period上的命名空间前缀urn

我有名称空间声明，但在这种情况下我不知道在哪里使用

1 个答案:

答案 0 :(得分：1)

首先，您需要正确生成XML片段并避免错误：

  

命名空间错误：未定义Period上的命名空间前缀urn

要合并名称空间前缀，请使用createElementNS()而不是createElement()：

$urn_uri = "urn:entsoe.eu:edi:ess:schedulemessage:3:3";

$period = $dom->createElementNS(urn_uri, "urn:Period");
$timeInterval = $dom->createElementNS(urn_uri, "urn:TimeInterval");
$resolution = $dom->createElementNS(urn_uri, "urn:Resolution");

...

正确生成每个片段后，请考虑XSLT（一种用于转换XML文件的专用语言），因为它维护document()函数以从外部XML文件进行解析。 PHP可以使用其php/xsl库运行XSLT 1.0脚本（可能需要启用扩展名）。

下面假定名称空间已在第二个和第三个片段的根中正确定义。 注意：如果片段格式不正确，此XSLT解决方案将无法使用。

XSLT （另存为.xsl文件，一个特殊的.xml文件） 

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                              xmlns:aut="http://www.domain.xy/OSB/Authentication/" 
                              xmlns:sch="http://www.domain.xy/schedule/ScheduleManager/" 
                              xmlns:urn="urn:entsoe.eu:edi:ess:schedulemessage:3:3">
  <xsl:output indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="urn:ScheduleMessage">
    <xsl:copy>
      <xsl:apply-templates select="*"/>
      <xsl:apply-templates select="document('2nd Part.xml')/urn:ScheduleTimeSeries"/>     
    </xsl:copy>
  </xsl:template>

  <xsl:template match="urn:ScheduleTimeSeries">
    <xsl:copy>
      <xsl:apply-templates select="*"/>
      <xsl:copy-of select="document('3rd Part.xml')/*"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>

PHP （仅在第一部分运行转换） 

// LOAD XML AND XSLT
$xml = new DOMDocument('1.0', 'UTF-8');
$xml->load('1st Part.xml');

$xsl = new DOMDocument('1.0', 'UTF-8');   
$xsl->load('Script.xsl');

// INITIALIZE TRANSFORMER
$proc = new XSLTProcessor;
$proc->importStyleSheet($xsl);

// RUN TRANSFORMATION
$newXML = $proc->transformToDoc($xml);

// ECHO TO CONSOLE
echo $newXML;

// SAVE TO FILE
file_put_contents('Output.xml', $newXML);

输出
