Hi,
My question is more towards XSLT and XPATH; specifically v1.0
Can we have relative XPATH variable in XSLT just like we do have reference variable in ESQL, so that we do not need to mention/parse from the root of a XML tree?
Thanks in advance. |

XPath is a published W3C standard. Use Google.

Thanks Kimbert. Definitely my query should have been more to the point.
So far I have seen relative paths to be used in case of loops in XPATH. So I was not sure about the usage of relative XPATHs in all cases and any performance benefit out of it. I'll try to learn more through google. |

For any tree based structure, I would expect that relative paths would limit the amount of node traversal required.
That is, if you are at A/B/C/D/E, and you want to iterate over the children of D... using a relative path from C will be shorter than having to navigate to every element starting at A. |
