您好，我刚刚从NCBI下载了一个指向埃及伊蚊5.8S区域的XML文件-核苷酸。作为示例，我将在第一个示例中获得的信息粘贴到文本中。
我想从这里提取
1. <INSDSeq_accession-version>CH477247.1</INSDSeq_accession-version>
2. <INSDSeq_update-date>23-MAR-2015</INSDSeq_update-date>
3. <INSDSeq_create-date>28-OCT-2005</INSDSeq_create-date>
4. <INSDReference_journal>Submitted (07-OCT-2005) Broad Institute of MIT and Harvard, 320 Charles Street, Cambridge, MA 02141, USA </INSDReference_journal>
而且，正如我所说的，这是我实际下载的所有信息的简短版本（13个样本）https://www.ncbi.nlm.nih.gov/nuccore/?term=aedes+aegypti+5.8，是否有可能提取所有样本所需的信息？
我对R很熟悉，但是哪个平台套件更好地做到这一点？

<INSDSeq_comment>The sequence for this assembly was produced jointly by The Broad Institute of Harvard/MIT and The Institute for Genomic Research. The assembly represents 7.6X sequence coverage of the genome and the total length of the contigs is 1.31 Gb. Additional information about the Aedes aegypti sequencing project and assembly can be found at http://www.broad.mit.edu/annotation/disease_vector/aedes_aegypti/ and http://www.tigr.org/msc/aedes/aedes.shtml. Long-term curation of the sequence and subsequent annotation updates will be the responsibility of VectorBase at http://www.vectorbase.org.~Annotation was updated by VectorBase in Sept 2012.</INSDSeq_comment>
