如何用DXL从Module2提取缺失编号补全Module1的[编号]内容？

Absolutely, this is totally achievable with IBM Rational DOORS DXL! Let's walk through how to build a script that handles this task smoothly.

Quick Assumptions to Start #

First, I need to clarify what "corresponding position" means for your modules—for this example, I’ll go with two common scenarios you might be working with:

• Either both modules share an identical hierarchical structure (so the nth object in Module1 maps directly to the nth object in Module2)
• Or objects in both modules have a unique identifier (like a custom "ID" attribute) that lets us match them up precisely

I’ll also assume:

• Module2’s valid numbers are wrapped in square brackets (e.g., [123])
• Module1’s missing entries are exactly the string [no number]

Practical DXL Script Example #

Here’s a working script that implements this logic—you can tweak it to fit your exact module setup:

// Open your target modules (replace the paths with your actual module locations)
Module mod1 = edit("C:/DOORS/Modules/Module1", false)
Module mod2 = read("C:/DOORS/Modules/Module2", false)

// Check if modules opened successfully
if (null mod1 || null mod2) {
    print "Error: Failed to open one or both modules. Double-check the paths!\n"
    exit
}

// Loop through every object in Module1
Object obj1
for obj1 in mod1 do {
    string objText = obj1."Object Text"
    // Look for objects with the missing number placeholder
    if (objText contains "[no number]") {
        // --- Choose your matching method below ---
        // Option 1: Match by object position (same index in both modules)
        Object obj2 = object(mod2, number(obj1))
        
        // Option 2: Match by a unique attribute (uncomment and adjust if needed)
        // string uniqueID = obj1."Unique ID"
        // Object obj2 = find(mod2, "Unique ID", uniqueID)
        
        // Skip if no matching object exists in Module2
        if (null obj2) {
            print "Warning: No match found for object " fullName(obj1) "\n"
            continue
        }
        
        // Extract the number from Module2's object text
        string obj2Text = obj2."Object Text"
        regexp numberPattern = /\[(\d+)\]/  // Regex to capture digits inside []
        if (match(numberPattern, obj2Text)) {
            string newNumber = "[" matchText(numberPattern, 1) "]"
            // Replace the placeholder with the valid number
            obj1."Object Text" = replace(objText, "[no number]", newNumber)
            print "Updated: " fullName(obj1) " → " newNumber "\n"
        } else {
            print "Warning: No valid [number] found in matching object " fullName(obj2) "\n"
        }
    }
}

// Save changes and clean up
save(mod1)
close(mod1)
close(mod2)
print "All updates completed!\n"

Key Tips for Customization #

• Matching Logic: Pick Option 1 or 2 based on how your modules are organized. If your modules don’t align by position, the attribute-based match (Option 2) is more reliable.
• Regex Tweaks: If your numbers include letters or special characters, adjust the regex pattern. For example, use \[([A-Za-z0-9-]+)\] to capture alphanumeric numbers with hyphens.
• Test First: Always run this script on a copy of your modules before using it on production data—better safe than sorry!
• Permissions: Make sure you have edit access to Module1 and read access to Module2, otherwise the script will fail.
