Integration

My requirement is to enable XML on OAS 10.1.3.5.
I am not sure how to configure it, so I stated using separate PHP5.2 to configure with XML enable on the server. After installation, when I am starting the opmn services I am getting below error. I think the error with platform. Which means current OS version is 64bit and php5.2 stage is 32bit version I guess.

OAS_HOME=/u20/app/MSRV1P/apmsrv1p/oracle/product/OAS
URL : http://nacisdell277.us.oracle.com:10330/phpinfo.php
I used below command to configure :
./configure prefix=$ORACLE_HOME/php with-config-file-path=$ORACLE_HOME/Apache/Apache/conf --with-apxs=$ORACLE_HOME/Apache/Apache/bin/apxs
with-oci8=instantclient,/u20/app/MSRV1P/apmsrv1p/oracle/product/instantclient_10_2 with-config-file-path=/u20/app/MSRV1P/apmsrv1p/oracle/product/OAS/Apache/Apache/php5--enable-sigchild enable-xml enable-simplexml enable-libxml enable-dom enable-simplexml enable-xml enable-xmlreader enable-xmlwriter enable-simplexml –with-xsl -with-zlib with-xml --with-libxml-dir

Error :
/u20/app/MSRV1P/apmsrv1p/oracle/product/OAS/Apache/Apache/bin/apachectl startssl: execing httpd
Syntax error on line 247 of /u20/app/MSRV1P/apmsrv1p/oracle/product/OAS/Apache/Apache/conf/httpd.conf:

I checked in the Metalink for “configuring php5 with enable XML on OAS 10.1.3.x” but I couldn’t find anything.
Please advise me on this.

Thanks
