如何使用Javascript查找内部文本 <g:id> 文本 </g:id> 并先粘贴 <g:mpn> 多布卢 </g:mpn> 标签

Question

How can I use Javascript to find text inside <g:id>Text</g:id> and paste on first <g:mpn>DOLBLUU</g:mpn> tag

Example: I want to loop through the XML document and find the <g:id> and get text and paste on the first <g:mpn> tag that it finds.

<item><g:id>DOLBLUU</g:id><g:mpn>DOLBLUU</g:mpn>

Does anyone know how to accomplish this?

If you are proposing to grab XML from a text area and parse it, then you should take a look at these Javascript XML-related libs. In particular, you might want to check out XPATH, which allows you to reference any part of an XML document, according to a nutty-but-powerful query syntax. If I understand what you're asking for, XPATH is probably it, but you'll see a few related items under "XML Technology" on the XML Parser Javascript docs page .

If I'm off the mark, perhaps you can provide samples of input and expected output with a little more explanation.
