It is a simple XML file you can use the wordpress function: get_search_results Or PHP's simplexml function: $file = file_get_contents('file.xml'); $dom = new DOMDocument(); $dom->loadXML($file); $newXml = new DOMXPath($dom); $xpath = new DOMXPath($dom); $results = $xpath->query('//author'); $xml_data = array(); foreach ($results as $result) { $xml_data[] = array( 'Author' => $result->getAttribute('author'), 'Link' => $result->getAttribute('link') ); } print_r($xml_data); B-cell BCR signalling in dendritic cells is required for maintaining T cell homeostasis. The balance of self-reactive versus protective T cells in the peripheral immune system is regulated by interactions between dendritic cells (DCs) and T cells. In this study, we have explored the role of antigen-specific BCR engagement in the maintenance of this equilibrium. We show that T cell activation in the presence of BCR cross-linking molecules induces DC maturation and migration. In addition, we show that activation of B cells by anti-IgD cross-linking in vivo causes similar effects on DCs and CD4(+) T cells. However, in vivo cross-linking of BCRs on CD4(+) T cells alone in a naive B-cell compartment does not induce DC maturation or migration. Indeed, in vitro stimulation of T cells with BCR-engaging mAbs does not induce DC maturation and does not impair T cell differentiation. We propose that DCs require antigen-specific BCR stimulation in vivo to establish a homeostatic balance between T cells and tolerance-inducing regulatory T cells (Tregs). This cross-talk between T cells and DCs is strictly BCR-dependent and independent of TCR stimulation.Chitosan-based coatings for biodegradable personal
