Question

我在将工厂机器生成的XML文件导入SQL表时遇到问题。如果我编辑该文件以删除其他命名空间，我会得到正确的结果，但是因为我们想要自动化这个过程是不可行的。

XML文件的开头看起来像这样;

<?xml version="1.0" encoding="UTF-8"?>
<LaneHistory xmlns="omlNamespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="omlNamespace C:\Program%20Files\Moba\Omnia%20MMI\MMI\bin\..\Application%20Data\XML\Schema\OML-LaneHistory.xsd">
<FileProperties>
    <MachineNumber>33309</MachineNumber>
    <CreationDateTime>2012-06-29T08:12:41</CreationDateTime>
    <ContentDescription>LaneHistory</ContentDescription>
    <Version>001</Version>
</FileProperties>
<Lane>
    <General>
        <StartDateTime>2012-06-29T05:50:02</StartDateTime>
        <StopDateTime>2012-06-29T06:20:07</StopDateTime>
        <LaneNumber>25</LaneNumber>
    </General>
    <Supply>
        <Property>
            <Name>Jones Heulyn Org Hse 3</Name>
            <AdditionalCode>UK20296=</AdditionalCode>
        </Property>
        <Identification>
            <TraceCode1>UK20296=</TraceCode1>
            <TraceCode2>633264</TraceCode2>

我尝试了以下内容;

DECLARE @XML AS XML, @hDoc AS INT, @SQL NVARCHAR (MAX), @rootxmlns varchar(MAX)
SELECT @XML = XMLData FROM XMLwithOpenXML
set @rootxmlns = '<LaneHistory xmlns="omlNamespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="omlNamespace C:\Program%20Files\Moba\Omnia%20MMI\MMI\bin\..\Application%20Data\XML\Schema\OML-LaneHistory.xsd">/'

EXEC sp_xml_preparedocument @hDoc OUTPUT, @XML, @rootxmlns

但得到错误;

XML解析错误0xc00ce553发生在第0行，靠近XML文本“”。消息6602，级别16，状态2，过程sp_xml_preparedocument，第1行[批次启动第33行] 错误描述是'以下标记未关闭：LaneHistory。'。

任何人都可以指出我正确的方向。

在我看来，你的命名空间很糟糕：

set @rootxmlns = '<LaneHistory xmlns="omlNamespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="omlNamespace C:\Program%20Files\Moba\Omnia%20MMI\MMI\bin\..\Application%20Data\XML\Schema\OML-LaneHistory.xsd">/'

你有＆＃34; /＆＃34;和＆＃34;＆gt;＆＃34;最后是错误的顺序。我想你只需要这个：

set @rootxmlns = '<LaneHistory xmlns="omlNamespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="omlNamespace C:\Program%20Files\Moba\Omnia%20MMI\MMI\bin\..\Application%20Data\XML\Schema\OML-LaneHistory.xsd"/>'

MSDN有一个示例XML命名空间：

'<ROOT xmlns:xyz="urn:MyNamespace"/>'

......供参考。

第2部分 - 所以你的查询什么都不返回，我想这是因为当你使用OPENXML查询你的XML时，你设置了以属性为中心的选项（1）。如果将其更改为以元素为中心的选项（2），那么它应该有效吗？我使用您的部分XML进行了一些测试，可以通过将选项从1更改为2来弹出机器编号。

从基本的角度来说，这是以属性为中心的XML：

<LaneHistory><FileProperties MachineNumber="33309"/></LaneHistory>

...这是以元素为中心的XML;

<LaneHistory><FileProperties><MachineNumber>33309</MachineNumber></FileProperties></LaneHistory>

因此，要清楚，您的OPENXML语句需要第三个参数，该参数应为2。

我终于修复了我必须将代码更改为以下内容的问题;

fabric.Image.prototype._render = function(ctx, noTransform) {
    /* This is the default behavior. I haven't modified anything in this part. */
    let x, y, imageMargins = this._findMargins(), elementToDraw;

    x = (noTransform ? this.left : -this.width / 2);
    y = (noTransform ? this.top : -this.height / 2);

    if (this.meetOrSlice === 'slice') {
        ctx.beginPath();
        ctx.rect(x, y, this.width, this.height);
        ctx.clip();
    }

    if (this.isMoving === false && this.resizeFilters.length && this._needsResize()) {
        this._lastScaleX = this.scaleX;
        this._lastScaleY = this.scaleY;
        elementToDraw = this.applyFilters(null, this.resizeFilters, this._filteredEl
            || this._originalElement, true);
    }
    else {
        elementToDraw = this._element;
    }

    /* My changes begin here. */
    if (elementToDraw && elementToDraw.naturalHeight > 0) {
        if (this.sizeMode === BadgingImageSizeMode.CenterImage) {
            drawCenterImage.apply(this, [ctx, elementToDraw, imageMargins, x, y]);
        } else {
            // Default _render behavior
            ctx.drawImage(elementToDraw,
                x + imageMargins.marginX,
                y + imageMargins.marginY,
                imageMargins.width,
                imageMargins.height);
        }
    }

    /* And they finish here. */
    this._stroke(ctx);
    this._renderStroke(ctx);
};

OpenXML无法使命名空间工作，可能是原始XML文件问题？
