Is there any way to inject meta nodes dynamically in to the runtime pages?

Hi Everyone,

I am trying to inject meta data node in to the generated html page.
i.e In the generated html I want the following meta nodes fields.
[PHP]
<meta name="product1" content="test1" />
<meta name="product2" content="test2" />
….
<meta name="productN" content="testN" />
[/PHP]
I know, we can add the meta node using following java code
[PHP]
Map pageData = context.getPageScopeData();
pageData.put(“test1”, “test1”);
[/PHP]
the issue is , we will have to add corresponding entry into the page configuration xml file. As per follow
[PHP]
ls:begin[meta-PageType]

product1
$PAGE_SCOPE[test1]

ls:end[meta-PageType]
[/PHP]

But, in my case I want to add multiple product types (it might be 0 to 100) and I don’t want to add static mapping for all 100 products.

Please let me know if there is any other way to pull the data in to the page configuration xml file to generate meta fields.

[PHP]
StringBuffer head = new StringBuffer();
head.append("<meta name="\"product1\"" content="\"test1\"" />");
head.append("<meta name="\"product2\"" content="\"test2\"" />");
head.append("<meta name="\"productN\"" content="\"testN\"" />");
String existingHead = (String) context.getPageScopeData().get(RuntimePage.PAGESCOPE_HEAD_INJECTION);
if (existingHead != null) {
/* Existing content takes precendence over this */
head.insert(0, existingHead);
}
context.getPageScopeData().put(RuntimePage.PAGESCOPE_HEAD_INJECTION, head.toString());
[/PHP]

And if, like me, the thought of manually building HTML as strings makes you itch, build it as a Dom4j Element and convert to String at the very end using [PHP]
List elements = headElement.elements();
for (Element el : elements) {
buf.append(el.asXML()).append("\n");
}
[/PHP]
