title: Magento Sitemap and / or Sitemap index issues? - XML, PHP?
body: <p>Can any help recommend the best strategy for our Magento Sitemap?</p>
  
  <p>We have a large Magento store with nearly 500,000 products. </p>
  
  <p>Obviously we therefore have a need to split our sitemap into 50,000 chunks and have a sitemap index file. The issue is creating these sitemaps regularly and splitting them down.</p>
  
  <p>When we create a sitemap using the feature on the Magento admin panel, it times out and goes to a white screen. We have tried an extension from Mageworx to split them down - but they couldn't get it working.</p>
  
  <p>What is the best way of having an automatically generating XML sitemap index, point to 10 or so sitemaps down from that?</p>
  
  <p>We are on Magento community, 1.5.1.0.</p>
