Merge two xml files in one xml files with php

Question

I have two XML files whose structure is the same but the content is different.

I tried to use many approaches but I could not find the right answer.

XML 1:

<Products>
<Product>
<Prdocut_Code>12345</Prdocut_Code>
<Prdocut_Desc>Product desc</Prdocut_Desc>
</Product>
</Products>

XML 2:

<Products>
<Product>
<Prdocut_Code>12345</Prdocut_Code>
<Prdocut_Price>12.5</Prdocut_Price>
</Product>
</Products>

How can I show the product code, description and price in the same file according to the product codes in a different single XML file, considering the multiple products in the XML files in this structure?

Answer 1

You need to parse both XML files, find common nodes, and then merge their leaves. At last, you build and write the new XML to a file.

You need to utilize an XML parser. PHP itself provides you with one . You can also utilize the DOMDocument class or even XPath . Or if you want a cleaner API, there is the Orchestral's XML Parser .

And good news for you; there's a 5 years old PHP XML merge script out there, if you don't want to write the solution yourself.
