Installing updates for glibc and libxml2

[pm]

Hi all,

I am using RHEL 3.0 on i386. I want to install the
latest version of libxml2 (2.6.23). So I downloaded
the rpm and when I run "rpm -ivh --force
libxml2-2.6.23-1.2.i386.rpm" to install it, I get the
following.

warning: libxml2-2.6.23-1.2.i386.rpm: V3 DSA
signature: NOKEY, key ID 4f2a6fd2
error: Failed dependencies:
        libc.so.6(GLIBC_2.3.4) is needed by
libxml2-2.6.23-1.2
        libc.so.6(GLIBC_2.4) is needed by
libxml2-2.6.23-1.2

I saw (by rpm -q glibc) that the version of glibc I
have is glibc-2.3.2-95.30. Where can I get the the
latest version of glibc and how should I install the
update (I mean, what command line to enter)? I
downloaded the compressed archive from gnu website,
but it seems to have only the sources. Can I get the
rpm from somewhere?

Also I saw that there is already libxml2 installed.
How can I install the latest version on top of the
existing one?

Thanks for any help.
