修改此正则表达式以仅选择紧邻的特定标签而不是同级标签

Question

我正在使用 Visual Studio Code 对充满 XML 文件的文件夹运行查找/替换。

我需要删除具有特定字符串“S00BBABHK”的所有 LineItem 节点。

注意：此代码的格式是为了清晰起见，我正在使用的文件中的实际 XML 是一行，并且没有以任何方式格式化。

            <LineItem sequence="0">
                ...
                    <Item id="GOOD_1" />
                ...
            </LineItem>     
            <LineItem sequence="0">
                ...
                    <Item id="GOOD_2" />
                ...
            </LineItem>
            <LineItem sequence="0">
                ...
                    <Item id="S00BBABHK" />
                ...
            </LineItem>
            <LineItem sequence="0">
                ...
                    <Item id="Good3" />
                ...
            </LineItem>     

这是示例文件的内容。 注意：这些文件仅包含一行，并且未以任何方式格式化。

我正在使用以下正则表达式：

`<LineItem.*?sequence="[^>]*>.*(?=S00BBABHK).*<\/LineItem>`

如果在任何节点中找到查询字符串，则选择给定文件中的所有 LineItem 节点。

我不知道如何修改它以仅选择包含查询字符串的 LineItem 节点。

这不是脚本的一部分。我在 VS Code 中使用正则表达式作为搜索/替换查询。 （Mac、OS 12.7.4、Visual Studio Code 1.86.2）我每天都会修改一批这些内容（直到上游源解决问题）。

提前感谢您的指导和耐心。

使用使用 Xml Linq 的 Powershell 脚本

using assembly System.Xml.Linq
$input_filename = 'c:\temp\test.xml'
$output_filename = 'c:\temp\test1.xml'

$doc = [System.Xml.Linq.XDocument]::Load($input_filename)
$items = $doc.Descendants('LineItem').Foreach( [System.Xml.Linq.XElement])
$length = $items.Count - 1
for($i = $length; $i -ge 0; $i--)
{
   $item = $items[$i]
   $id = $item.Element('Item').Attribute('id').Value
   if($id -eq 'S00BBABHK') { $item.Remove() }
}
$doc.Save($output_filename)
